The x68k-specific portion of the NetBSD 1.2 release is found in the "x68k" subdirectory of the distribution. That subdirectory is laid out as follows: .../NetBSD-1.2/x68k/ binary/ x68k binary distribution sets; see below. floppies/ x68k boot and installation floppies; see below. utils/ installation utilities which runs on Human68k. There are three floppy images in the "x68k/floppies" subdirectory of the NetBSD 1.2 distribution. One is bootable kernel-copy floppy, one is "inst12.fs", which is used to install NetBSD/x68k for the first time, and one is "upgr12.fs", which is used in upgrading the system from the previous version of NetBSD/x68k. Bootable Kernel-copy floppy: These disks contain file systems, are bootable, and have enough utilities on board to copy a new kernel to your hard disk once you have it partitioned for NetBSD. They make upgrading to a new kernel easy, because all you have to do is get a new kernel-copy floppy with a new kernel, boot from it, and confirm that you want to have the kernel copied to your disk. Installation floppy: This disk contains the software necessary to prepare your hard drive for NetBSD and install the NetBSD distribution. It is not bootable, and must be used in conjunction with one of the kernel-copy floppies. This floppy is named "inst12.fs". Upgrade floppy: This disk contains the software to be used in upgrading the system from a previous version of NetBSD. It is not bootable, and must be used in conjunction with one of the kernel-copy floppies. This floppy is named "upgr12.fs". The NetBSD/x68k binary distribution sets contain the binaries which comprise the NetBSD 1.2 release for the x68k. There are seven binary distribution sets. The binary distribution sets can be found in subdirectories of the "x68k/binary" subdirectory of the NetBSD 1.2 distribution tree, and are as follows: base12 The NetBSD/x68k 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, 22.8M uncompressed ] comp12 The NetBSD/x68k 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. [ 5.3M gzipped, 17.5M 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.) [ 68K gzipped, 358K uncompressed ] games12 This set includes the games and their manual pages. [ 2.8M gzipped, 7.0M 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. [ 0.9M gzipped, 3.5M 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 ] For other platform, there is a security distribution named "secr12" is provided. It contains the files which cannot be exported outside the United States and Canada. Since all the developers of the NetBSD/x68k live in Japan, the x68k security distribution is not provided in the binary form. The x68k 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 x68k 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 xvfp" 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.
