INSTALL(8) NetBSD System Manager's Manual INSTALL(8) NAME INSTALL - Installation procedure for NetBSD/pmax DESCRIPTION About this Document This document describes the installation procedure for NetBSD 1.4.3 on the pmax platform. It is available in four different formats titled INSTALL.ext, where ext is one of .ps, .html, .more, or .txt. .ps PostScript. .html Standard internet HTML. .more The enhanced text format used on Unix-like systems by the more(1) and less(1) pager utility programs. This is the format in which the on-line man pages are generally pre- sented. .txt Plain old ASCII. You are reading the ASCII version. What is NetBSD? The NetBSD Operating System is a fully functional Open Source UN*X-like operating system derived from the Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2 sources. NetBSD runs on twenty different system architectures featuring eight distinct families of CPUs, and is being ported to more. The NetBSD 1.4.3 release contains complete binary releases for fifteen different machine types. (The remaining ones are not fully supported at this time and are thus not part of the binary distri- bution. For information on them, please see the NetBSD web site at http://www.netbsd.org/) NetBSD is a completely integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, The X Window System, and nu- merous other tools, all accompanied by full source code. NetBSD is a creation of the members of the Internet community. Without the unique cooperation and coordination the net makes possible, it's likely that NetBSD wouldn't exist. Upgrade path to NetBSD 1.4.3 If you are not installing your system ``from scratch'' but instead are going to upgrade an existing system already running NetBSD you need to know which versions you can upgrade with NetBSD 1.4.3. NetBSD 1.4.3 is an upgrade of NetBSD 1.4.2, 1.4.1, NetBSD 1.4 and earlier major and patch releases of NetBSD such as versions 1.3.3, 1.2 etc. The intermediate development versions of code available on the main trunk in our CVS repository (also known as ``NetBSD-current'') from after the point where the release cycle for 1.4 was started are designated by ver- sion identifiers such as 1.4A, 1.4B, 1.4P etc. These identifiers do not designate releases, but indicate major changes in internal kernel APIs. Note that the kernel from NetBSD 1.4.3 can not be used to upgrade a sys- tem running one of those intermediate development versions. Trying to use the NetBSD 1.4.3 kernel on such a system will in all probability re- sult in problems. Please also note that it is not possible to do a direct ``version'' com- parison between any of the intermediate development versions mentioned above and 1.4.3 to determine if a given feature is present or absent in 1.4.3. The development of 1.4 and the subsequent patch or ``point'' re- leases is done on a separate branch in the CVS repository which was cre- ated when the release cylcle for 1.4 was started, and during the release cycle of 1.4 and its patch releases, selective fixes have been imported from the main development trunk (the intent is to only import fixes with no or minor impact on the stability of the release branch). So, there are features in 1.4.3 which were not in e.g. 1.4H, but the reverse is al- so true. Major Changes Between 1.4.2 and 1.4.3 The complete list of changes between NetBSD 1.4.2 and 1.4.3 can be found in the file CHANGES-1.4.3 in the top directory of the source tree. The following are the highlights only. o A driver for the Lucent Wavelan (Orinoco) 802.11B wireless Ethernet PCMCIA card has been added, see wi(4). o The PCI Cyclom-4Y and -8Y multiport serial cards are now supported. o The Macintosh LC Ethernet Adapter is now supported. o The on-board video on Macintosh Quadra 605 is now supported. o Bugfixes to the Alteon Gigabit Ethernet driver, ti(4). o Support for several new PCI IDE controllers have been added, see pciide(4.) o The i386 port may now be installed on wd2 or wd3. o A possible CPU hog problem related to large I/Os has been fixed. Fixes SA#2000-005. o A denial-of-service problem related to handling of IP options has been fixed. Fixes SA#2000-002. o A problem with /etc/ftpchroot has been fixed. Fixes SA#2000-006. o A minor problem related to locking of semaphore resources has been fixed. Fixes SA#2000-004. o The DHCP software has been updated to ISC 2.0pl3. This also fixes SA#2000-008 -- a security problem in the dhcp client code. o A problem with use of user-supplied data as a format string in ftpd has been fixed. Fixes SA#2000-009. o The sparc c++rt0.o code is now compiled with -fPIC. This means that libraries with global constructors (which must link in c++rt0.o on sparc/a.out) must also be compiled -fPIC. o Most countries can now import the full release without restriction, including the previously restricted domestic portion. The only ``problem spots'' are US-embargoed countries. See http://www.NetBSD.ORG/Misc/crypto-export.html for the full details. o An extensive audit of the code (and corresponding fixes) has been done to eliminate possible buffer overruns caused by possible user- specified format strings. In addition, many bugs have been fixed -- more than 40 problems reported through our problem tracking system have been fixed, and some other non- reported problems have also been found and fixed. See the CHANGES-1.4.3 file for the complete list. Known caveats with 1.4.3 The following are the major known issues with NetBSD 1.4.3. o Some of the fixes in NetBSD 1.4.3 required the introduction of a new system call, issetugid(2). This means that you will have to upgrade the kernel before installing the new user-land code. o The more strict format checking required a minor fix to the C compil- er to allow NULL format strings. Thus, you will need to update your compiler before doing a ``make build'' during a source-based upgrade. o PCMCIA support may require manual adjustment to function properly. See Possible PCMCIA issues under Installing the NetBSD System for more details. o No major changes have been made to LFS in 1.4.3, so it is still of ``beta test'' quality. o The version of the IPF packet filtering software in NetBSD 1.4.3 must be enabled with ``ipf -E'' before filtering rules can be set. Fail- ure to do so may result in a panic. (Enabling NAT will however auto- enable IPF.) Major Changes Between 1.4.1 and 1.4.2 The complete list of changes between NetBSD 1.4.1 and 1.4.2 can be found in the file CHANGES-1.4.2 in the top directory of the source tree. The following are the highlights only. o A driver for the Alteon Gigabit Ethernet cards has been added, see ti(4). o A driver for the Realtek 8129/8239 Fast Ethernet PCI cards have been added, see rl(4). o A driver for the DPT SmartCache and SmartRAID III or IV SCSI adapters has been added, see dpt(4). o A driver for the BOCA IOAT66 6-port ISA serial adapter has been added, see ioat(4). o Support for the X-surf Amiga board has been added. o Support has been added for ext2fs revision 1, with read-only support for the ``sparse super'' and the ``filetype'' options. o BIND has been upgraded to version 8.2.2-P5. o The IPF packet filtering software has been updated to version 3.3.6. o Tcpdump now does hex/ascii dumps of packet contents if asked to do so. o An implementation of the System V user management utilities has been added. o The name ``errno'' is now always a macro which expands to a function call. This is done to ease the integration of thread libraries with the code in both system and third-party libraries. Please include to access the correct definition of ``errno''. o A utility for making temporary files for shell scripts has been added, see mktemp(1). o The automounter utility amd(8) has been updated to fix a security problem. o A security problem in procfs has been fixed. Procfs is not used by default in NetBSD. o The floating point emulation on the ports using the m68k CPU has been reverted to the version in NetBSD 1.4 (the version in 1.4.1 had prob- lems). o Several subsystems have received substantial work, such as RAIDframe, LFS, and the package tools. In addition, many, many bugs have been fixed -- more than 100 problems reported through our problem tracking system have been fixed, and many other non-reported problems have also been found and fixed. See the CHANGES-1.4.2 file for the complete list. Known caveats with 1.4.2 The following are the major known issues with NetBSD 1.4.2. o The upgrade of ipf(8) caused a change of the kernel API. Thus, if you are using ipf(8) you need to upgrade both the kernel and the us- er-land utilities to control that feature in order for it to work. o As part of fixing a kernel bug, ``struct vfsnode'' needed to change size. This will unfortunately, and contrary to tradition for patch releases, cause incompatibilities for users of file system LKMs com- piled for 1.4 and 1.4.1. o Although LFS has been improved between 1.4.1 and 1.4.2, it can proba- bly still be characterized as being of ``beta test'' quality, e.g. filling the file system still gives ``interesting'' effects. It should probably not be used to store critical data quite yet. o The version of the IPF packet filtering software in NetBSD 1.4.2 must be enabled with ``ipf -E'' before filtering or NAT rules can be set. Failure to do so may result in a panic. Major Changes Between 1.4 and 1.4.1 The complete list of changes between NetBSD 1.4 and 1.4.1 can be found in the file CHANGES-1.4.1 in the top directory of the source tree. o The NetBSD/alpha port's compatibility for Digital UNIX executables has been greatly improved. o Many bug fixes and improvements of the installation tools and utili- ties. o Support for more PCI serial/parallel cards has been added. o It is now possible to boot NetBSD/i386 on systems with 1GB of RAM. o The floating point emulation on the ports using the m68k CPU has been upgraded. o A fatal problem with /dev/random has been found and fixed. o Support for Alpha 21264 ev6 based systems has been added to NetB- SD/alpha. Major Changes Between 1.3 and 1.4 The NetBSD 1.4 release is a substantial improvement over its predeces- sors. We have provided numerous significant functional enhancements, in- cluding support for many new devices, integration of hundreds of bug fix- es, new and updated kernel subsystems, and many userland enhancements. The results of these improvements is a stable operating system fit for production use that rivals most commercially available systems. It is impossible to completely summarize the nearly two years of develop- ment that went into the NetBSD 1.4 release. Some highlights include: o Substantial improvements in the TCP/IP implementation, including nu- merous performance enhancements and bug fixes by Jason Thorpe and others. o A new, high efficiency kernel memory pool allocator by Paul Kranen- burg. This has been integrated into most kernel subsystems. o A new, totally rewritten virtual memory subsystem, UVM, created by Chuck Cranor, which is substantially cleaner and better performing than the old Mach derived VM subsystem. o Improved POSIX and XPG standards compliance. o Completion of the integration of all remaining 4.4BSD Lite-2 kernel improvements and bug fixes that had not been previously integrated. (Integration of all userland components was completed before NetBSD 1.3) o Several new ports, including macppc, bebox, sparc64, next68k, and others, have been integrated into the source tree. o The system compilers have been upgraded to egcs 1.1.1, and the system compiler toolchain now (mostly) uses the latest versions of GNU binu- tils instead of the obsolete versions left over from 4.4BSD Lite. o Everyone's favorite ftp(1) client has been improved even further. See the man page for details. o A new architecture independent console driver, wscons(4), has been integrated into many ports. o Numerous improvements have been made to the audio subsystem support, including support for MIDI device drivers. o Linux compatibility support has been improved. o A number of scheduler enhancements have yielded dramatic improvements in interactive performance and better control of background tasks. o Several network tunneling protocols, including GRE and IP in IP, have been implemented. o Kernel support for the CODA distributed file system has been added. o Manuel Bouyer completed major changes to the IDE support. It is now architecture independent. Major changes have been made to the IDE code for better error handling, improved ATAPI support, 32 bit data I/O support and bus-master DMA support on PCI IDE controllers. o Lennart Augustsson has added full USB support, permitting the use of a wide variety of Universal Serial Bus peripherals. The drivers should easily port to any future platforms that support the PCI bus. See usb(4) for an overview. o RAIDframe, version 1.1, from the Parallel Data Laboratory at Carnegie Mellon University, has been integrated. Supports RAID levels 0, 1, 4, 5, and more. o Luke Mewburn added nsswitch.conf(5) functionality to the system to specify the search order for system databases. o syslogd(8) now supports listening on multiple sockets, to make the chrooting of servers easier. o Most third party packages have been updated to the latest stable re- lease. As has been noted, there have also been innumerable bug fixes. Kernel interfaces have continued to be refined, and more subsystems and device drivers are shared among the different ports. You can look for this trend to continue. This is the fourth public major release of NetBSD for the DECstation and DECsystem family of computers. Significantly, this is the first release for the pmax that builds completely from in-tree source code. Some other pmax-specific changes from the 1.3 release include: o A much easier-to-use ramdisk-based install procedure. o New two-stage disk bootblocks that can load a.out, ECOFF and ELF ker- nels. o a.out kernels are no longer built. ELF is the preferred format for kernels loaded off disk, and ECOFF kernels are still required for netbooting. a.out kernels will still boot. o Better support for SFB graphics cards running at different resolu- tions. o NetBSD/pmax now uses the X11R6 Xserver. o Mouse problems in X on 5000/xx machines have been significantly re- duced. o Some improvements in the SCSI driver for the 5000/200 (although some problems are still thought to exist). o scc serial driver will work up to 115.2k bps on some systems. o Reworked model-dependent code, including support for 5100 (but not recently tested on this machine). o Crash dumps now work. o Switched to in-tree ld.elf_so. o Breakpoints in gdb work more reliably for R3000 systems (although there still may be some problems with R4X00 systems). The Future of NetBSD The NetBSD Foundation has been incorporated as a non-profit organization. Its purpose is to encourage, foster and promote the free exchange of com- puter software, namely the NetBSD Operating System. The foundation will allow for many things to be handled more smoothly than could be done with our previous informal organization. In particular, it provides the framework to deal with other parties that wish to become involved in the NetBSD Project. The NetBSD Foundation will help improve the quality of NetBSD by: o providing better organization to keep track of development efforts, including co-ordination with groups working in related fields. o providing a framework to receive donations of goods and services and to own the resources necessary to run the NetBSD Project. o providing a better position from which to undertake promotional ac- tivities. o periodically organizing workshops for developers and other interested people to discuss ongoing work. We intend to begin narrowing the time delay between releases. Our ambi- tion is to provide a full release every six to eight months. We hope to support even more hardware in the future, and we have a rather large number of other ideas about what can be done to improve NetBSD. We intend to continue our current practice of making the NetBSD-current development source available on a daily basis. In addition, Anonymous CVS access to the NetBSD source tree has been added since NetBSD 1.4.1; see http://www.netbsd.org/Changes/#anoncvs-available We have also added a browsable CVS repository on the web at http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/ We intend to integrate free, positive changes from whatever sources sub- mit them, providing that they are well thought-out and increase the us- ability of the system. Above all, we hope to create a stable and accessible system, and to be responsive to the needs and desires of NetBSD users, because it is for and because of them that NetBSD exists.

NetBSD 1.4.3 Release Contents The root directory of the NetBSD 1.4.3 release is organized as follows: .../NetBSD-1.4.3/ BUGS Known bugs list (somewhat incomplete and out of date). CHANGES Changes since earlier NetBSD releases. LAST_MINUTE Last minute changes. MIRRORS A list of sites that mirror the NetBSD 1.4.3 distribution. README.files README describing the distribution's contents. TODO NetBSD's todo list (also somewhat incomplete and out of date). patches/ Post-release source code patches. source/ Source distribution sets; see below. In addition to the files and directories listed above, there is one di- rectory per architecture, for each of the architectures for which NetBSD 1.4.3 has a binary distribution. There are also 'README.export- control' files sprinkled liberally throughout the distribution tree, which spell out the current restrictions related to export of this code from the United States of America. Note that these regulations were re- cently changed so that most countries can import the entire release with- out significant restrictions. See http://www.NetBSD.ORG/Misc/crypto-export.html which contains up-to-date information on this issue. The source distribution sets can be found in subdirectories of the "source" subdirectory of the distribution tree. They contain the complete sources to the system. The source distribution sets are as follows: secrsrc.tgz: This set contains the "domestic" sources. These sources may be subject to United States export regulations. 423K gzipped, 2M uncompressed gnusrc.tgz: This set contains the "gnu" sources, including the source for the compiler, assembler, groff, and the other GNU utilities in the binary distribution sets. 19M gzipped, 84.3M uncompressed syssrc.tgz: This set contains the sources to the NetBSD 1.4.3 ker- nel, config(8), and dbsym(8). 13.9M gzipped, 68.8M uncompressed sharesrc.tgz: This set contains the "share" sources, which include the sources for the man pages not associated with any par- ticular program, the sources for the typesettable docu- ment set, the dictionaries, and more. 3.1M gzipped, 11.8M uncompressed src.tgz: This set contains all of the NetBSD 1.4.3 sources which are not mentioned above. 14.5M gzipped, 67.5M uncompressed Most of the above source sets are located in the source/sets subdirectory of the distribution tree. The secrsrc.tgz set is contained in the source/security subdirectory. This set contains the sources normally found in /usr/src/domestic - primarily Kerberos (version 4) and other cryptographic security related software. This code can now be exported from the US to most countries. The document on http://www.NetBSD.ORG/Misc/crypto-export.html spells out the current (rather lenient) restrictions applicable for the export of this code. The source sets are distributed as compressed tar files. They may be un- packed into /usr/src with the command: cat set_name.tgz | gunzip | (cd /; tar xpf - ) The sets/Split/ and security/Split/ subdirectories contain split versions of the source sets for those users who need to load the source sets from floppy or otherwise need a split distribution. The split sets are are named "set_name.xx" where "set_name" is the distribution set name, and "xx" is the sequence number of the file, starting with "aa" for the first file in the distribution set, then "ab" for the next, and so on. All of these files except the last one of each set should be exactly 240,640 bytes long. (The last file is just long enough to contain the remainder of the data for that distribution set.) The split distributions may be reassembled and extracted with cat as follows: cat set_name.?? | gunzip | (cd /; tar xpf - ) In each of the source distribution set directories, there is a file named CKSUMS which contains the checksums of the files in that directory, as generated by the cksum(1) utility. You can use cksum to check the in- tegrity of the archives, if you suspect that one of the files is corrupt and have access to a cksum binary. Checksums based on other algorithms may also be present - see the release(7) man page for details. NetBSD/pmax Subdirectory Structure The pmax-specific portion of the NetBSD 1.4.3 release is found in the pmax subdirectory of the distribution: .../NetBSD-1.4.3/pmax/ INSTALL.html INSTALL.ps INSTALL.txt INSTALL.more Installation notes; this file. The .more file contains underlined text using the more(1) conventions for indicat- ing italic and bold display. binary/ sets/ pmax binary distribution sets; see below. kernel/ pmax installation kernels. security/ pmax security distribution; see below. installation/ diskimage/ pmax miniroot file system image; see below. misc/ New bootblocks necessary for booting non a.out kernels. netboot/ Server tar file for diskless machines. Binary Distribution Sets The NetBSD pmax binary distribution sets contain the binaries which com- prise the NetBSD 1.4.3 release for the pmax. There are eight binary dis- tribution sets and the security distribution set. The binary distribu- tion sets can be found in the pmax/binary/sets subdirectory of the NetBSD 1.4.3 distribution tree, and are as follows: base The NetBSD 1.4.3 pmax base binary distribution. You must in- stall this distribution set. It contains the base NetBSD utilities that are necessary for the system to run and be minimally functional. It includes shared library support, and excludes everything described below. 13.2M gzipped, 41.8M uncompressed comp Things needed for compiling programs. This set includes the system include files (/usr/include) and the various system libraries (except the shared libraries, which are included as part of the base set). This set also includes the manual pages for all of the utilities it contains, as well as the system call and library manual pages. 11.6M gzipped, 49.4M uncompressed etc This distribution set contains the system configuration files that reside in /etc and in several other places. This set must be installed if you are installing the system from scratch, but should not be used if you are upgrading. (If you are upgrading, it's recommended that you get a copy of this set and carefully upgrade your configuration files by hand.) 59K gzipped, 380K uncompressed games This set includes the games and their manual pages. 2.9M gzipped, 7.7M uncompressed kern This set contains a NetBSD/pmax 1.4.3 GENERIC kernel, named /netbsd. You must install this distribution set. 817k gzipped, 2.1M uncompressed man This set includes all of the manual pages for the binaries and other software contained in the base set. Note that it does not include any of the manual pages that are included in the other sets. 4.1M gzipped, 16.4M uncompressed misc This set includes the (rather large) system dictionaries, the typesettable document set, and other files from /usr/share. 2.2M gzipped, 8.5M uncompressed text This set includes NetBSD's text processing tools, including groff(1), all related programs, and their manual pages. 1.3M gzipped, 5.1M uncompressed The pmax security distribution set is named secr and can be found in the pmax/binary/security subdirectory of the NetBSD 1.4.3 distribution tree. It contains security- related binaries which depend on cryptographic source code. You do not need this distribution set to use encrypted passwords in your password file; the base distribution includes a crypt library which can perform only the one-way encryption function. The security distribution includes a version of the Kerberos IV network security system, and a Kerberized version of telnet(1) program. The secr distribution set can be found only on those sites which carry the complete NetBSD distribution and which can legally obtain it. Because of United States law, it may not be legal to distribute this set to locations outside of the United States and Canada. See http://www.NetBSD.ORG/Misc/crypto-export.html for updated information on this issue. 1M gzipped, 4.2M uncompressed NetBSD maintains its own set of sources for the X Window System in order to assure tight integration and compatibility. These sources are based on XFree86, and tightly track XFree86 releases. They are currently equivalent to XFree86 3.3.6. Binary sets for the X Window system are distributed with NetBSD. The sets are: xbase The basic files needed for a complete X client environment. This does not include the X servers. 3.1M gzipped, 11M uncompressed xcomp The extra libraries and include files needed to compile X source code. 2.1M gzipped, 9.8M uncompressed xcontrib Programs that were contributed to X. 207k gzipped, 770k uncompressed xfont Fonts needed by X. 5.5M gzipped, 6.7M uncompressed xserver The Xpmax server with man page. 1.8M gzipped, 5.6M uncompressed The pmax binary distribution sets are distributed as gzipped tar files named with the extension .tgz, e.g. base.tgz. The instructions given for extracting the source sets work equally well for the binary sets, but it is worth noting that if you use that method, the files are /-relative and therefore are extracted below the current directory. That is, if you want to extract the binaries into your system, i.e. replace the system binaries with them, you have to run the tar xfp command from /. Note Each directory in the pmax binary distribution also has its own checksum files, just as the source distribution does: All BSDSUM files are historic BSD checksums for the various files in that directory, in the format produced by the command: cksum -o 1 file All CKSUM files are POSIX checksums for the various files in that directory, in the format produced by the command: cksum file. All MD5 files are MD5 digests for the various files in that direc- tory, in the format produced by the command: cksum -m file. All SYSVSUM files are historic AT&T System V UNIX checksums for the various files in that directory, in the format produced by the command: cksum -o -2 file. The MD5 digest is the safest checksum, followed by the POSIX checksum. The other two checksums are provided only to ensure that the widest possible range of system can check the integrity of the release files. NetBSD/pmax System Requirements and Supported Devices NetBSD/pmax 1.4.3 runs on the following classes of machines: o DECstation 2100 and 3100, also known as pmin and pmax o Personal DECstations (5000/20, /25 and /33) also known as MAXINE o DECstation 5000/120, /125, and /133, also known as 3MIN o DECstation 5000/200, also known as 3MAX o DECstation 5000/240 and DECsystem 5900, also known as 3MAXPLUS o DECstation 5000/50, 5000/150, 5000/260 (and DECsystem 5900-260) - R4000 and R4400 variants of the the MAXINE, 3MIN and 3MAXPLUS NetBSD/pmax 1.4.3 does not (yet) run on these machines: o DECsystem 5100 (an r3000-based cousin of the DECstation 3100) o DECsystem 5400 and 5500 (Qbus-based systems, similar to the Vax Mayfair or Mayfair II, but with an r2000a or r3000 cpu instead of a CVAX cpu.) o DECsystem 5800 (xbi-based multiprocessor, a Vax 6200 with Vax CPU boards replaced with Mips cpu boards) The minimal configuration requires 8M of RAM and ~60M of disk space. To install the entire system requires much more disk space, and to run X or compile the system, more RAM is recommended. (NetBSD with 8M of RAM feels like Ultrix with 8M of RAM.) Note that until you have around 16M of RAM, getting more RAM is more important than getting a faster CPU. Supported devices include: o DECstation 2100 and 3100 baseboard video - one-bit mono or 8-bit pseudocolour frame buffers. o DECstation 5000 series TurboChannel video - PMAG-DV Personal DECstation baseboard 1024x768 frame buffer - PMAG-BA 1024x768 8-bit colour frame buffer - PMAGB-BA 1024x768 8-bit colour frame buffer - PMAG-AA 1280x1024 four-bit greyscale frame buffer Note All supported DECstation video produces sync-on-green. Be sure to use either a DEC-compatible fixed-sync monitor or a multisync monitor that supports sync-on-green. o serial ports: - ttya and ttyb (can be used as console if needed) o ethernet: - on-board AMD Lance ethernet ((le0)), - TURBOchannel AMD Lance ethernet cards (the PMAD) o SCSI: - on-board DEC sii SCSI controller (2100 and 3100) - on-board asc SCSI controller (5000 series machines) - TurboChannel asc SCSI controller (the PMAZ) o DEC (LK-201 or compatible) keyboard o DEC hockey puck or compatible mouse Hardware the we do not currently support, but get questions about from time to time: o Q-bus DECsystem machines o DECsystem 5100 machines o PrestoServe NVRAM on DECsystem 5100 and 5000/2xx machines o audio drivers for Personal DECstation machines o floppy driver for Personal DECstation machines o TurboChannel audio hardware (LoFi) o PMAG-C 2-D (PX) and other accelerated framebuffers (PXG, PXG+ and PXG+ Turbo) with onboard i860 processors Note the primary obstacle to support of all but the very last item is non-availability of sample hardware for development. The primary obstacle for the i860-based framebuffers is that there is no documentation on the accelerator board. There is support for the PX and PXG framebuffers in NetBSD-current after NetBSD 1.4. Getting the NetBSD System on to Useful Media First-time installation on a bare machine is not supported, because most DECstations do not have any suitable load device. Some versions of DEC- station PROM s are buggy and will not boot via TFTP and bootp; still oth- er versions are buggy and do not boot via MOP. The only DECstation with a floppy-disk drive is the Personal DECstation, and that device is not supported as a boot device. The recommended installation procedure is to boot an install kernel via TFTP, or to use a ``helper'' system to write a miniroot diskimage onto a disk, move that disk to the target installation system, and then boot the miniroot. Installation is supported from several media types, including: o NFS partitions o FTP o Tape o CD-ROM The steps necessary to prepare the distribution sets for installation de- pend on which installation medium you choose. The steps for the various media are outlined below. NFS Installation Place the NetBSD distribution sets you wish to install into a directory on an NFS server, and make that direc- tory mountable by the machine on which you are in- stalling or upgrading NetBSD. This will probably re- quire modifying the /etc/exports file on of the NFS server and resetting its mount daemon (mountd). Both of these actions will probably require superuser privi- leges on the server. You will need to know the IP address of your nameserver or of your NFS server, and, if the server is not on a network directly connected to the machine on which you're installing or upgrading NetBSD, you need to know the IP address of the closest router . Finally, you need to know the IP address of the NetBSD machine it- self. The install program will ask you to provide this information to be able to access the sets via NFS. If you are using a diskless setup to install NetBSD on your machine, you can take advantage of the fact that the above has already been done on your machine's serv- er. So, you can conveniently put the NetBSD file sets in your machine's root filesystem on the server where the install program can find them. Once the NFS server is set up properly and you have the information mentioned above, you can start the actual installation process. FTP Installation Determine an FTP site from which you can retrieve the NetBSD distribution when you're about to install. You will need to know the IP address of your nameserver or of your ftp site, and, if it's not on a network direct- ly connected to the machine on which you're installing or upgrading NetBSD, you need to know the IP address of the closest router. Finally, you need to know the IP address of the NetBSD machine itself. The install pro- gram will ask you to provide this information to be able to access the sets via ftp. Once you have this information, you can proceed to the actual installation. Tape Installation To install NetBSD from a tape, you need to somehow get the NetBSD filesets you wish to install on your system on to the appropriate kind of tape, in tar format. Note the tape devices with which NetBSD/pmax is be- lieved to work is the DEC TK-50. This is a very slow device. Installation via disk or network is recommended if at all possible. If you're making the tape on a UN*X system, the easiest way to do so is: tar cvf tape_device files where tape_device is the name of the tape device that describes the tape drive you're using (possibly some- thing like /dev/nrst0, but we make no guarantees 8-). Under SunOS 5.x, this would be something like /dev/rmt/0mbn. Again, your mileage may vary. If you can't figure it out, ask your system administrator. files are the names of the set_name.nnn files which you want to be placed on the tape. Once you have done this, you can proceed to the next step in the installation process, preparing your system for NetBSD installation. CD-ROM Installation If you are installing from a CD-ROM, the distribution sets are already in the proper format and no special handling is required. Preparing your System for NetBSD Installation First and foremost, before beginning the installation process, make sure you have a reliable backup of any data on your hard disk that you wish to keep. Mistakes in partitioning your hard disk may lead to data loss. Installing the NetBSD System Note There may be updates to this procedure available from the NetB- SD/pmax web page, at http://www.netbsd.org/Ports/pmax. To install or upgrade NetBSD, you need to first boot an installation pro- gram and then interact with the screen-menu program sysinst. The instal- lation program actually consists of the NetBSD kernel plus an in-memory file system of utility programs. From most convenient to least convenient, the installation methods are: 1. Installation from an existing NetBSD or Ultrix system by booting the install kernel from an existing root filesystem. See the Installing from an existing system section later in these INSTALL notes. 2. Copying a bootable diskimage onto the beginning of a disk and in- stalling onto that disk. See the Install via diskimage section lat- er in these INSTALL notes. 3. Booting the install kernel over the network and installing onto a local disk. See the Install via netboot install kernel section lat- er in these INSTALL notes. 4. Using a helper machine with a SCSI controller to copy the bootable diskimage onto the beginning of a disk, and moving the disk to the target machine. See the Install via diskimage section later in these INSTALL notes. 5. For machines with some PROMs that cannot netboot standard kernels, you will need to set up an NFS server with a diskless root filesys- tem for trimmed-down network install kernel and run the installation system from the NFS root filesystem. See the Install via diskless boot section later in these INSTALL notes. You should familiarize yourself with the console PROM environment and the hardware configuration. The PROMs on the older DECstation 2100 and 3100 use one syntax. The PROMs on the TurboChannel machines use a completely different syntax. Be sure you know how to print the configuration of your machine, and how to boot from disk or network, as appropriate. On the 2100/3100, that's boot -f rz(0,N,0)netbsd (boot from rzN) boot -f tftp() (boot diskless via TFTP) boot -f mop() (boot via MOP from an Ultrix server) On the 5000/200, the equivalent is boot 5/rzN/netbsd boot 6/tftp boot 6/mop And on other 5000 series machines, boot 3/rzN/netbsd boot 3/tftp boot 3/mop You will also need to know the total size (in sectors) and the approxi- mate geometry of the disks you are installing onto, so that you can label your disks for the BSD fast filesystem (FFS). For most SCSI drives (in- cluding all SCSI-2 drives), the kernel will correctly detect the disk ge- ometry. The sysinst tool will suggest these as the default. If you're installing NetBSD/pmax for the first time it's a very good idea to pre-plan partition sizes for the disks on which you're installing NetBSD. Changing the size of partitions after you've installed is diffi- cult. If you do not have a spare bootable disk, it may be simpler to re- install NetBSD again from scratch. Assuming a classic partition scheme with separate root (`/') and /usr filesystems, a comfortable size for the NetBSD root filesystem partition is about 32M. A good initial size for the swap partition is twice the amount of physical memory in your machine (though, unlike Ultrix, there are no restrictions on the size of the swap partition that would render part of your memory unusable). The default swap size is 64Mbytes, which is adequate for doing a full system build. A full binary installation, with X11R6.3, takes about 150MB in `/usr' - a 200MB `/usr' should be am- ple. Install via a NetBSD CDROM You can obtain the disk image or diskless boot tar file from the NetBSD 1.4.3 CDROM. To mount the CDROM from a NetBSD/pmax host, type mount -r -t cd9660 /dev/rzXc /mnt and from an Ultrix host mount -r -t cdfs -o nodefperm,noversion /dev/rzXc /mnt where X is the SCSI id of the CDROM. Note Ultrix does not have Rock Ridge extensions so leave out everything between the first and last period (.) in the paths on the CD. For example, the path NetBSD-1.3.2 would show up as NetBSD-1.2. The diskimage file can be found on the CDROM at the following location (relative to the mount point of the CD) pmax/installation/diskimage/diskimage.gz and the diskless boot tar file can be found at pmax/installation/netboot/diskimage.tgz Once you have located these files, continue on to either Install via netboot install kernel, Install via diskless boot, Install via diskimage or Installing from an existing system section later in the INSTALL notes. Installing from an existing system Note If you are installing NetBSD using an existing NetBSD system that is older than NetBSD-1.4, you will need to install new bootblocks before installing NetBSD-1.4.3. New bootblocks are in the tar file: pmax/installation/misc/bootblocks.tgz in the NetBSD-1.4.3 distribution. To install the new bootblocks, use the following commands: # cd / # tar xvpfz .../pmax/installation/misc/bootblocks.tgz # disklabel -B rzX where X is your boot disk SCSI ID. With new NetBSD bootblocks or using the Ultrix bootloader, you can boot the kernel located in: pmax/binary/kernel/install.gz On Ultrix systems you will need to gunzip this kernel before booting it. A copy of the gunzip binary for Ultrix systems is located in: pmax/installation/misc/gunzip.ultrix Then boot using: >> boot -f rz(0,X,0)install >> boot 5/rzX/install or >> boot 3/rzX/install where X is your boot disk SCSI ID, and continue to the Once you've booted the diskimage section Install via diskimage The diskimage file is in pmax/installation/diskimage/diskimage.gz. It is shipped compressed and is around 1150 kbytes, uncompressing to ex- actly 2 Mbytes. To install the diskimage onto disk rzX on a NetBSD/pmax system, do: disklabel -W /dev/rrzXc gunzip -c diskimage.gz | dd of=/dev/rrzXc bs=10240 When installing on a disk with no NetBSD or Ultrix label, you may get a message like: rzX: WARNING: trying Ultrix label, no disk label or when installing on an old Ultrix disk, you may get a message like: rzX: WARNING: using ULTRIX partition information when issuing the "disklabel -W /dev/rrzXc" command. This can safely be ignored. Most other NetBSD ports are similar, but use rsdXc instead of rrzXc. On NetBSD/i386, the `raw disk partition' is the 'd' parttion, so do: disklabel -W /dev/rsdXd gunzip -c diskimage.gz | dd of=/dev/rsdXd bs=10240 On NetBSD, be sure to use disklabel -W to enable writing to the label area of the disk. If you forget this and/or use the `block' device, the dd command may silently fail. On Ultrix systems, do: gunzip -c diskimage.gz | dd of=/dev/rrzXc bs=10240 A copy of the gunzip program is located in pmax/installation/misc/gunzip.ultrix if you do not already have it. On MS-DOS, use an unzip utlility, then use rawrite. Then boot using: >> boot -f rz(0,X,0)netbsd >> boot 5/rzX/netbsd or >> boot 3/rzX/netbsd where X is your boot disk SCSI ID, and continue to the Once you've booted the diskimage section. Install via netboot install kernel Booting NetBSD/pmax 1.4.3 install kernel over a network requires a BOOTP or DHCP server and a TFTP server. (These are usually all run on the same machine.) There are two basic stages to the boot: o The pmax PROM software sends a BOOTP request to get its own address, the address of the TFTP server and the file to download. o It downloads the file name obtained from BOOTP, which is the install kernel, via TFTP and then executes it. You will need to set up servers for BOOTP and TFTP. For the BOOTP server you need to specify the: o hardware type (Ethernet) o hardware address (Ethernet MAC address) o IP address of the client o subnet mask of the client o address of the TFTP server o name of the kernel loaded via TFTP Here's an example for a Unix system running bootpd: myhost.mydom.com:\ :ht=ethernet:ha=08002b123456:\ :ip=192.168.1.2:sm=255.255.255.0:\ :sa=192.168.1.1:bf=install:\ :rp=/usr/export/pmax: And here's an example for a Unix system running the ISC dhcpd: host pmax { hardware ethernet 08:0:2b:12:34:56; fixed-address 192.168.1.2; option host-name "myhost.mydom.com"; filename "install"; option domain-name-servers 192.168.1.1; option broadcast-address 255.255.255.0; option domain-name "my.domain"; option root-path "/usr/export/pmax"; } For the TFTP server, You will need to copy the install.ecoff kernel to the directory used by the TFTP server. This file must be gunziped. Then boot using: >> boot -f tftp() >> boot 6/tftp or >> boot 3/tftp and continue to the Once you've booted the diskimage section. Install via diskless boot The file pmax/installation/netboot/diskimage.tar.gz contains a suitable set of files for installing on an NFS server to set up a diskless root filesytem. (It is a tar copy of the contents of an installation ramdisk filesystem contained in the install kernel.) You will need to find an NFS server, unpack the tarfile, and setup BOOTP/dhcp service for your pmax. Instructions for setting up an NFS server and diskless booting are on the NetBSD/pmax netboot webpage at http://www.netbsd.org/Ports/pmax/netboot.html Since the system install utility, sysinst, requires a read/write root, installing via diskless boot is only feasible if your NFS server exports the diskless root read-write. If this is not possible, you should in- stall via other of the other installation procedures. Once you have booted the kernel, continue to the Once you've booted the diskimage section. Once you've booted the diskimage Once you'e booted the installation kernel you will need to select your terminal type. Use pmax for a framebuffer console, vt100 for a serial console with a vt100-compatible terminal, or xterm or xterms for a tip(1) or cu(1) connection running in an xterm(1). The system will then start the sysinst program. Running the Sysinst Installation Program 1. Introduction Using sysinst, installing NetBSD is a relatively easy process. You still should read this document and have it in hand when doing the installation process. This document tries to be a good guideline for the installation and as such covers many details to be completed. Do not let this discourage you, the install program is not hard to use. 2. General The following is a walk-through of the steps you will take while getting NetBSD installed on your hard disk. sysinst is a menu driv- en installation system that allows for some freedom in doing the in- stallation. Sometimes, questions will be asked and in many cases the default answer will be displayed in brackets (``[ ]'') after the question. If you wish to stop the installation, you may hit Control- C at any time, but if you do, you'll have to begin the installation process again from scratch. 3. Quick install First, let's describe a quick install. The other sections of this document go into the installation procedure in more detail, but you may find that you do not need this. If you want detailed instruc- tions, skip to section 3. This section describes a basic installa- tion, using a CD-ROM install as an example. o What you need. - The distribution sets (in this example, they are on CD). - A CD-ROM drive (SCSI or ATAPI), a harddisk and a minimum of 8Mb of memory installed. - The harddisk should have at least 200 + n megabytes of space free, where n is the number of megabytes of main memory in your system. If you wish to install the X window system as well, you will need at least 60Mb more. o The Quick Installation - Boot the system as desribed in the previous section. You should be at the sysinst main menu. - If you wish, you can configure some network settings immedi- ately by choosing the utilities menu and then configure network. It isn't actually required at this point, but it may be more convenient. Go back to the main menu. - Choose install - You will be guided through some steps regarding the setup of your disk, and the selection of distributed components to install. When in doubt, refer to the rest of this document for details. - After your disk has been prepared, choose CD-ROM as the medium. The default values for the path and device should be ok. - After all the files have been unpacked, go back to the main menu and select reboot, after you have removed the bootflop- py from the drive. - NetBSD will now boot. You should log in as root, and set a password for that account. You are also advised to edit the file /etc/rc.conf to match your system needs. - Your installation is now complete. - For configuring the X window system, if installed, see the files in /usr/X11R6/lib/X11/doc. Further information can be found on http://www.xfree86.org/ 4. Booting NetBSD Boot the system as desribed in the previous section. Once NetBSD has booted and printed all the boot messages, you will be presented with a welcome message and a main menu. It will also include instructions for using the menus. 5. Network configuration If you will not use network operation during the installation, but you do want your machine to be configured for networking once it is installed, you should first go to the utilities menu, and select Configure network option. If you only want to temporarily use net- working during the installation, you can specify these parameters later. If you are not using Domain Name Service (DNS), you can give an empty response in reply to answers relating to this. 6. Installation drive selection and parameters To start the installation, select the menu option to install NetBSD from the main menu. The first thing is to identify the disk on which you want to install NetBSD. sysinst will report a list of disks it finds and ask you for your selection. Depending on how many disks are found, you may get a different message. You should see disk names like rz0 or rz1 7. Partitioning the disk. o Which portion of the disk to use. You will be asked if you want to use the entire disk or only part of the disk. If you decide to use the entire disk for NetBSD, it will be checked if there are already other systems present on the disk, and you will be asked to confirm whether you want to overwrite these. If you want to use the entire disk for NetBSD, you can skip the following section and go to Editing the NetBSD disklabel. o Editing the NetBSD disklabel. The partition table of the NetBSD part of a disk is called a disklabel. There are 3 layouts for the NetBSD part of the disk that you can pick from: Standard, Standard with X and Custom. The first two use a set of default values (that you can change) suitable for a normal installation, possibly including X. The last option lets you specify everything yourself. You will be presented with the current layout of the NetBSD disklabel, and given a chance to change it. For each partition, you can set the type, offset and size, block and fragment size, and the mount point. The type that NetBSD uses for normal file storage is called 4.2BSD. A swap partition has a special type called swap. Some partitions in the disklabel have a fixed purpose. Partition a is always the root partition, b is the swap partition, and c is the whole disk. Partitions e-h are available for other use. Traditionally, d is the partition mounted on the /usr directory, but this is historical practice, not a fixed value. You will then be asked to name your disk's disklabel. The de- fault response is mydisk. For most purposes this will be OK. If you choose to name it something different, make sure the name is a single word and contains no special characters. You don't need to remember this name. 8. Preparing your hard disk You are now at the point of no return. Nothing has been written to your disk yet, but if you confirm that you want to install NetBSD, your hard drive will be modified. If you are sure you want to pro- ceed, enter yes at the prompt. The install program will now label your disk and make the file sys- tems you specified. The filesystems will be initialized to contain NetBSD bootstrapping binaries and configuration files. You will see messages on your screen from the various NetBSD disk preparation tools that are running. There should be no errors in this section of the installation. If there are, restart from the beginning of the installation process. Otherwise, you can continue the installation program after pressing the return key. 9. Getting the distribution sets. The NetBSD distribution consists of a number of sets, that come in the form of gzipped tarfiles. A few sets must be installed for a working system, others are optional. At this point of the installa- tion, you will be presented with a menu which enables you to choose from one of the following methods of installing the sets. Some of these methods will first load the sets on your hard disk, others will extract the sets directly. For all these methods, the first step is making the sets available for extraction, and then do the actual installation. The sets can be made available in a few different ways. The following sections describe each of those methods. After reading the one about the method you will be using, you can continue to section 9 10. Installation using ftp To be able to install using ftp, you first need to configure your network setup, if you haven't already at the start of the install procedure. sysinst will do this for you, asking you to provide some data, like IP number, hostname, etc. If you do not have name service set up for the machine that you are installing on, you can just press return in answer to these questions, and DNS will not be used. You will also be asked to specify the host that you want to transfer the sets from, the directory on that host, and the account name and password used to log into that host using ftp. If you did not set up DNS when answering the questions to configure networking, you will need to specify an IP number instead of a hostname for the ftp serv- er. sysinst will proceed to transfer all the default set files from the remote site to your hard disk. 11. Installation using NFS To be able to install using NFS, you first need to configure your network setup, if you haven't already at the start of the install procedure. sysinst will do this for you, asking you to provide some data, like IP number, hostname, etc. If you do not have name service set up for the machine that you are installing on, you can just press return in answer to these questions, and DNS will not be used. You will also be asked to specify the host that you want to transfer the sets from, and the directory on that host that the files are in. This directory should be mountable by the machine you are installing on, i.e. correctly exported to your machine. If you did not set up DNS when answering the questions to configure networking, you will need to specify an IP number instead of a host- name for the NFS server. 12. Installation from CD-ROM When installing from a CD-ROM, you will be asked to specify the de- vice name for your CD-ROM player (usually cd0), and the directory name on the CD-ROM where the distribution files are. sysinst will then check if the files are indeed available in the specified location, and proceed to the actual extraction of the sets. 13. Installation from an unmounted filesystem In order to install from a local filesystem, you will need to speci- fy the device that the filesystem resides on (for example rz1e) the type of the filesystem, and the directory on the specified filesys- tem where the sets are located. sysinst will then check if it can indeed access the sets at that location. 14. Installation from a local directory This option assumes that you have already done some preparation yourself. The sets should be located in a directory on a filesystem that is already accessible. sysinst will ask you for the name of this directory. 15. Extracting the distribution sets After the install sets containing the NetBSD distribution have been made available, you can either extract all the sets (a full instal- lation), or only extract sets that you have selected. In the latter case you will be shown the currently selected sets, and given the opportunity to select the sets you want. Some sets always need to be installed (kern, base and etc) they will not be shown in this selec- tion menu. Before extraction begins, you can elect to watch the files being ex- tracted; the name of each file that is extracted will be shown. This can slow down the installation process considerably, especially on machines with slow graphics consoles or serial consoles. After all the files have been extracted, all the necessary device node files will be created. If you have already configured network- ing, you will be asked if you want to use this configuration for normal operation. If so, these values will be installed in the net- work configuration files. 16. Finalizing your installation. Congratulations, you have successfully installed NetBSD 1.4.3. You can now reboot the machine, and boot from harddisk. Post installation steps Once you've got the operating system running, there are a few things you need to do in order to bring the system into a propperly configured state, with the most important ones described below. 1. Configuring /etc/rc.conf If you haven't done any configuration of /etc/rc.conf, the system will drop you into single user mode on first reboot with the message /etc/rc.conf is not configured. Multiuser boot aborted. and with the root filesystem mounted read-write. When the system asks you to choose a shell, simply hit return to get to a prompt. If you are asked for a terminal type, respond with the correct terminal type as discussed in the Once you've booted the diskimage section. and hit return. At this point, you need to configure at least one file in the /etc directory. Change to the /etc directory and take a look at the /etc/rc.conf file. Modify it to your tastes, making sure that you set rc_configured=YES so that your changes will be enabled and a multi-user boot can proceed. If your /usr directory is on a separate partition and you do not know how to use 'ed' or 'ex', you will have to mount your /usr partition to gain access to 'vi'. Do the following: mount /usr export TERM=termtype If you have /var on a seperate partition, you need to repeat that step for it. After that, you can edit /etc/rc.conf with vi(1). When you have finished, type exit at the prompt to leave the single-user shell and continue with the multi-user boot. Other values that need to be set in /etc/rc.conf for a networked en- vironment are hostname and possibly defaultroute, furthermore add an ifconfig_int for your interface , along the lines of ifconfig_le0="inet 123.45.67.89 netmask 255.255.255.0" or, if you have myname.my.dom in /etc/hosts: ifconfig_le0="inet myname.my.dom netmask 255.255.255.0" To enable proper hostname resolution, you will also want to add an /etc/resolv.conf file or (if you are feeling a little more adventur- ous) run named(8). See resolv.conf(5) or named(8) for more informa- tion. Other files in /etc that are new to NetBSD 1.4 and may require modi- fication or setting up include /etc/mailer.conf, /etc/nsswitch.conf and /etc/wscons.conf. 2. Logging in After reboot, you can log in as root at the login prompt. There is no initial password, but if you're using the machine in a networked environment, you should create an account for yourself (see below) and protect it and the "root" account with good passwords. 3. Adding accounts Use the vipw(8) command to add accounts to your system, do not edit /etc/passwd directly. See adduser(8) for more information on the process of how to add a new user to the system. 4. The X Window System If you have installed the X window system, look at the files in /usr/X11R6/lib/X11/doc for information. Don't forget to add /usr/X11R6/bin to your path in your shell's dot file so that you have access to the X binaries. 5. Installing 3rd party packages There is a lot of software freely available for Unix-based systems, almost all of which can run on NetBSD. Modifications are usually needed to when transferring programs between different Unix-like systems, so the NetBSD packages collection incorporates any such changes necessary to make that software run on NetBSD, and makes the installation (and deinstallation) of the software packages easy. There's also the option of building a package from source, in case there's no precompiled binary available. Precompiled binaries can be found at ftp://ftp.netbsd.org/pub/NetBSD/packages/ Package sources for compiling packages can be obtained by retrieving the file ftp://ftp.netbsd.org/pub/NetBSD/NetBSD- current/tar_files/pkgsrc.tar.gz They are typically extracted into /usr/pkgsrc (though other loca- tions work fine), as with the command: cat pkgsrc.tar.gz | gunzip | (mkdir /usr/pkgsrc; cd /usr/pkgsrc; tar xpf - ) After extracting, then see the README file in the extraction direc- tory (e.g. /usr/pkgsrc/README) for more information. 6. Misc o To adjust the system to your local timezone, point the /etc/localtime symlink to the appropriate file under /usr/share/zoneinfo. o Edit /etc/aliases to forward root mail to the right place (run newaliases(1) afterwards.) o The /etc/sendmail.cf file will almost definitely need to be ad- justed; files aiding in this can be found in /usr/share/sendmail. See the README file there for more infor- mation. o Edit /etc/rc.local to run any local daemons you use. o Many of the /etc files are documented in section 5 of the manu- al; so just invoking man filename is likely to give you more information on these files. Upgrading a previously-installed NetBSD System The upgrade to NetBSD 1.4.3 is a binary upgrade; it can be quite diffi- cult to advance to a later version by recompiling from source due primar- ily to interdependencies in the various components. To do the upgrade, you must install new bootblocks and boot off the install kernel as described in the Installing from an existing system section. You must also have at least the base and kern binary distribu- tion sets available, so that you can upgrade with them, using one of the upgrade methods described above. Finally, you must have sufficient disk space available to install the new binaries. Since the old binaries are being overwritten in place, you only need space for the new binaries, which weren't previously on the system. If you have a few megabytes free on each of your root and /usr partitions, you should have enough space. Since upgrading involves replacing the boot blocks on your NetBSD parti- tion, the kernel, and most of the system binaries, it has the potential to cause data loss. You are strongly advised to back up any important data on your disk, whether on the NetBSD partition or on another operat- ing system's partition, before beginning the upgrade process. The upgrade procedure using the sysinst tool is similar to an installa- tion, but without the hard disk partitioning. Another difference is that existing configuration files in /etc are backed up and merged with the new files. Getting the binary sets is done in the same manner as the in- stallation procedure; refer to the installation part of the document for how to do this. Also, some sanity checks are done, i.e. filesystems are checked before unpacking the sets. After a new kernel has been copied to your hard disk, your machine is a complete NetBSD 1.4.3 system. However, that doesn't mean that you're fin- ished with the upgrade process. You will probably want to update the set of device nodes you have in /dev. If you've changed the contents of /dev by hand, you will need to be careful about this, but if not, you can just cd into /dev , and run the command sh MAKEDEV all You must also deal with certain changes in the formats of some of the configuration files. The most notable change is that the options given to many of the file systems in /etc/fstab have changed, and some of the file systems have changed names. To find out what the new options are, it's suggested that you read the manual page for the file systems' mount com- mands, for example mount_nfs(8) for NFS. Finally, you will want to delete old binaries that were part of the ver- sion of NetBSD that you upgraded from and have since been removed from the NetBSD distribution. Compatibility Issues With Previous NetBSD Releases Users upgrading from previous versions of NetBSD may wish to bear the following problems and compatibility issues in mind when upgrading to NetBSD 1.4.3 Note Only issues effecting an upgrade from NetBSD 1.3 or NetBSD 1.3.x are decribed here. o "machine" directory/link in "/usr/include" Description Some architecture may fail to install the comp set because the /usr/include/machine directory changed to a symbolic link in NetBSD 1.4. Fix If this happens, you can use the command # rm -r /usr/include/machine to remove the old directory and it contents and reinstall the comp set. Using online NetBSD documentation Documentation is available if you first install the manual distribution set. Traditionally, the ``man pages'' (documentation) are denoted by ``name(section)''. Some examples of this are o intro(1), o man(1), o apropros(1), o passwd(1), and o passwd(5). The section numbers group the topics into several categories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administrative information is in section 8. The man command is used to view the documentation on a topic, and is started by entering man [section] topic. The brackets [] around the sec- tion should not be entered, but rather indicate that the section is op- tional. If you don't ask for a particular section, the topic with the lowest numbered section name will be displayed. For instance, after log- ging in, enter man passwd to read the documentation for passwd(1). To view the documentation for passwd(5)m enter man 5 passwd instead. If you are unsure of what man page you are looking for, enter apropos subject-word where subject-word is your topic of interest; a list of possibly related man pages will be displayed. Administrivia If you've got something to say, do so! We'd like your input. There are various mailing lists available via the mailing list server at majordomo@NetBSD.ORG. To get help on using the mailing list server, send mail to that address with an empty body, and it will reply with instruc- tions. There are various mailing lists set up to deal with comments and ques- tions about this release. Please send comments to: netbsd- comments@NetBSD.ORG. To report bugs, use the send-pr(1) command shipped with NetBSD, and fill in as much information about the problem as you can. Good bug reports in- clude lots of details. Additionally, bug reports can be sent by mail to: netbsd-bugs@NetBSD.ORG. Use of send-pr(1) is encouraged, however, because bugs reported with it are entered into the NetBSD bugs database, and thus can't slip through the cracks. There are also port-specific mailing lists, to discuss aspects of each port of NetBSD. Use majordomo to find their addresses. If you're inter- ested in doing a serious amount of work on a specific port, you probably should contact the "owner" of that port (listed below). If you'd like to help with this effort, and have an idea as to how you could be useful, send us mail or subscribe to: netbsd-help@NetBSD.ORG. As a favor, please avoid mailing huge documents or files to these mailing lists. Instead, put the material you would have sent up for FTP some- where, then mail the appropriate list about it, or, if you'd rather not do that, mail the list saying you'll send the data to those who want it. Thanks go to o The former members of UCB's Computer Systems Research Group, includ- ing (but not limited to): Keith Bostic Ralph Campbell Mike Karels Marshall Kirk McKusick for their ongoing work on BSD systems, support, and encouragement. o Also, our thanks go to: Mike Hibler Rick Macklem Jan-Simon Pendry Chris Torek for answering lots of questions, fixing bugs, and doing the various work they've done. o UC Berkeley's Experimental Computing Facility provided a home for sun-lamp in the past, people to look after it, and a sense of humor. Rob Robertson, too, has added his unique sense of humor to things, and for a long time provided the primary FTP site for NetBSD. o Vixie Enterprises for hosting the NetBSD FTP, WWW and SUP server. o Redback Networks, Inc. for hosting the NetBSD Mail server. o Without CVS, this project would be impossible to manage, so our hats go off to Brian Berliner, Jeff Polk, and the various other people who've had a hand in making CVS a useful tool. o Dave Burgess burgess@cynjut.infonet.net has been maintaining the 386BSD/NetBSD/FreeBSD FAQ for quite some time, and deserves to be recognized for it. o The following individuals and organiztions (each in alphabetical or- der) have made donations or loans of hardware and/or money, to sup- port NetBSD development, and deserve credit for it: Steve Allen Jason Birnschein Mason Loring Bliss Jason Brazile Mark Brinicombe David Brownlee Simon Burge Dave Burgess Ralph Campbell Brian Carlstrom James Chacon Bill Coldwell Charles Conn Tom Coulter Charles D.

(Obviously, there are a lot more people who deserve thanks here. If you're one of them, and would like to mentioned, tell us!) We are...
