The i386-specific portion of the NetBSD 1.2 release is found in the "i386" subdirectory of the distribution. That subdirectory is laid out as follows: .../NetBSD-1.2/i386/ INSTALL Installation notes; this file. binary/ i386 binary distribution sets; see below. floppies/ i386 boot and installation floppies; see below. security/ i386 security distribution; see below; utils/ Miscellaneous i386 installation utilities; see installation section, below. There are four i386 floppy images to be found in the "i386/floppy" subdirectory of the NetBSD 1.2 distribution. All are bootable. Two of them are installation floppies, two are upgrade floppies. They are all described in more detail below. There are gzipped versions of each available, for easier downloading. (The gzipped versions have the ".gz" extension added to their names.) Bootable installation floppies: These disks are bootable, and contain the software necessary to prepare your hard drive for NetBSD and install the NetBSD distribution. Unlike previous NetBSD releases, there is no seperate "kernel copy" floppy. Instead, the install floppy contains only a special compressed kernel with a built in ramdisk image of the installation file system. Because the kernel on the installation disks is not suitable for use beyond initial installation and configuration, a "generic" kernel has been placed in a distribution set named "kern12D". This kernel is intended to run your system while you build a custom kernel. It is strongly encouraged that you build a custom kernel for your installation rather than use the prebuilt generic kernel on a long term basis. Please note that because of space considerations the kernels booted from the installation floppies do not contain drivers that are not needed during installation -- in particular, no drivers needed to run the X Window System are available in these kernels. The "inst12D.fs" floppy is the installation floppy that should be used by most users. The "insts12D.fs" "small install" floppy contains a "small" installation kernel lacking some space intensive and lesser used drivers, especially the driver for the Western Digital WD7000 SCSI controller. The "small install" floppies are suitable for use on machines with four megabytes of memory, which will not boot the "inst12D.fs" floppy. If you have more than four megabytes of memory, you will probably be better off with the "inst12D.fs" floppy. Bootable upgrade floppies: These disks contains the software to be used in upgrading the system from a previous version of NetBSD. They are bootable, and are otherwise nearly identical in description to the installation floppies described above. The NetBSD/i386 binary distribution sets contain the binaries which comprise the NetBSD 1.2 release for the i386. There are eight binary distribution sets and the "security" distribution set. The binary distribution sets can be found in subdirectories of the "i386/binary" subdirectory of the NetBSD 1.2 distribution tree, and are as follows: base12 The NetBSD/i386 1.2 base binary distribution. You MUST install 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. [ 7.5M gzipped, 19.5M uncompressed ] comp12 The NetBSD/i386 Compiler tools. All of the tools relating to C, C++, and FORTRAN (yes, there are two!). This set includes the system include files (/usr/include), the linker, the compiler tool chain, 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. [ 4.9M gzipped, 15.0M uncompressed ] etc12 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.) [ 63K gzipped, 338K uncompressed ] games12 This set includes the games and their manual pages. [ 2.8M gzipped, 6.9M uncompressed ] kern12D This set contains a NetBSD/i386 1.2D GENERIC kernel, named "/netbsd". You MUST install this distribution set. [ .8M gzipped, 1.7M uncompressed ] man12 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. [ 0.8M gzipped, 3.4M uncompressed ] misc12 This set includes the system dictionaries (which are rather large), the typesettable document set, and man pages for other architectures which happen to be installed from the source tree by default. [ 1.9M gzipped, 6.6M uncompressed ] text12 This set includes NetBSD's text processing tools, including groff, all related programs, and their manual pages. [ 0.8M gzipped, 2.9M uncompressed ] IMPORTANT: In previous versions of NetBSD, the kernel from the install floppy was copied onto the hard drive in a special step. In the new install system, the kernel on the floppy is unsuited to being copied onto the hard drive. Instead, a new set, "kern", has been added which contains a generic kernel to be unloaded onto the drive. It must be extracted in order to have a minimally functioning system. The i386 security distribution set is named "secr12" and can be found in the "i386/security" subdirectory of the NetBSD 1.2 distribution tree. It contains crypt.c (the source file for the DES encryption algorithm) and the binaries which depend on it, as well as the "bdes" DES encryption program. You do not need this distribution set to use encrypted passwords in your password file; the "base12" distribution includes a crypt library which can perform only the decryption function. The security distribution also includes a version of the Kerberos IV network security system, and a Kerberized version of the "telnet" program. The "secr12" distribution set can be found only on those sites which carry the complete NetBSD distribution and which can legally obtain it. (Remember, because of United States law, this distribution set may not be exported to locations outside of the United States and Canada.) [ 154K gzipped, 358K uncompressed ] The i386 binary distribution sets are distributed in the same form as the source distribution sets; catted together, the members of a set form a gzipped tar file. Each i386 binary distribution set also has its own "CKSUMS" file, just as the source distribution sets do. 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 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" from /. Also note that if you upgrade or install this way, those programs that you are using at the time will NOT be replaced. If you follow the normal installation or upgrade procedures, this will be taken care of for you.
