The mac68k-specific portion of the OpenBSD 2.1 release is found in the "mac68k" subdirectory of the distribution. That subdirectory is laid out as follows: .../2.1/mac68k/ INSTALL.mac68k This file utils/ The mac68k installation utilities for MacOS. The OpenBSD/mac68k binary distribution sets contain all the binaries which are need to run the OpenBSD 2.1 release for the mac68k. There are eight binary distribution sets. The binary distribution sets can be found in the "mac68k/" of the OpenBSD 2.1 distribution tree, and are as follows: bsd21 The OpenBSD/mac68k 2.1 kernel binary. You MUST install this file. It is the kernel that you need to boot the system. [ 1.2MB uncompressed ] bsd21-genericsbc The OpenBSD/mac68k kernel binary. This is identical in every way to bsd21.tar.gz accept that it enables a different SCSI driver which may allow some otherwise incompatible SCSI disks to function with OpenBSD/mac68k. You must install either this or bsd21.tar.gz. [ 1.2MB uncompressed ] base21.tar.gz The OpenBSD/mac68k 2.1 base binary distribution. You MUST install this distribution set. It contains the base OpenBSD utilities that are necessary for the system to run and be minimally functional. It includes shared library support, and excludes everything described below. [ 11.6MB gzipped, 35.8MB uncompressed ] comp21.tar.gz The OpenBSD/mac68k Compiler tools. All of the tools relating to C, C++, and FORTRAN (yes, there are two!). This set includes the system header 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. It is very almost a must to install this set if one wants an even minimally functional system. [ 7.4MB gzipped, 23.8MB uncompressed ] etc21.tar.gz 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.) [ 90K gzipped, 450K uncompressed ] game21.tar.gz This set includes the BSD games and their manual pages. It's installation is optional. [ 2.8MB gzipped, 6.9MB uncompressed ] man21.tar.gz 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. Installation of this set is completely optional but is highly recommended. [ 2.4MB gzipped, 9.3MB uncompressed ] misc21.tar.gz 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 as well as many other sundry system files and programs. This set is not necessarry but will improve the functionallity of many system programs. [ 1.7MB gzipped, 6.1MB uncompressed ] text21.tar.gz This set includes OpenBSD's text processing tools, including groff, all related programs, and their manual pages. This set is highly recommended as these programs are depended upon for such basic system functions as reading manual pages. [ 0.9MB gzipped, 3.6MB uncompressed ] The directory '../2.1/mac68k/utils' contains a number of utilities for the MacOS to aid the installation and configuration of OpenBSD. The files in this directory are as follows: booter.sea.hqx This MacOS program is used to load the OpenBSD kernel and start the operating system. In all cases, you will need to download this file. installer.hqx This is the MacOS program used to install downloaded sets (such as those from the bins directory) onto a BSD partition. It is necessarry in either the case of a fresh install or an upgrade. mkfs.hqx A MacOS program to build BSD filesystems on various partitions you have created (see below). You will need this if you are performing a new installation.
