MINIX 1.5 FEATURES
Apple Macintosh Plus, SE, SE/30, II, IIcx, or IIx with at least 1M of RAM. An additional 1M of RAM and a hard disk is strongly recommended. MINIX has been tested primarily with version 6.0 and latter of the Apple system software. Problems may conceivably arise with earlier versions. Any hard disk or display that is supported by the normal Macintosh OS is also supported by MINIX.

I dont know how to use, not a Unix guru, but its complete etc...and the idea of a real multitasking thing with system 6.....;-) This morning I got a mail, explaing some of the mac specific commands. The Prentice-Hall book isnt on the net, but here is a snippet, maybe somebody is interested: << eject -- eject a diskette from a drive hdclose -- close hard disk partition hdopen -- set correspondence of a HD partition to a MacIntosh file maccreate -- create an empty MacIntosh file macfile -- list, read, and write MacIntosh volumes macread -- read a MacIntosh file macwrite -- write a MacIntosh file rmaker -- a simple resource compiler settype -- set type and/or creator of a Mac file >> Dont ask me for the details, ask around at comp.os.minix, thats where Linux started......... The URL for minix is ftp.cs.vu.nl/pub/minix etc...look for Macintosh. There are some manuals at, see the other snippet: << I should have mentioned in an earlier message that the entire Minix 1.5 reference manual is available at minix1.hampshire.edu in the /pub/refman.1.5 directory. Also a set of man pages for Minix 1.5 is available in /pub/minix.1.5/man. >> MacMinix Web Site Its not macspecific, but....... The hqx files from Amsterdam is around 5 MB, took me one hour with a 14400 GV, around the same time for decoding, so if you can sacrify two hours.. And then, I had to log in. Password ??? Voila: << the login name is root and the password is Geheim (it's case sensitive) hope that's what you need also, the extra users on there are: ast , Wachtwoold bin deamon you can edit the passwrods for all of them while logged on as root or as the user >> MacMinix is just a programm, there is MacBoot, you doubleclick on it etcpp. No difficult HD manipulations needed. Read the files in etc to get some kind of a clue, whats going on. First thing I did was to write a .kermcr file for ast, set line /dev/tty3 etc., next thing will be some other file in /etc that I can log into the SE from the outside. Heiko
MacMinix 040 Cache Fix
Thanks to Chris Hanson for this fix!
Here is what Chris posted to the comp.os.minix newsgroup:
Quite a while ago, I worked out how and when to flush caches so I could leave my Centris' 040 running at full blast. This is the result of those efforts.
It adds an optional "flush040()" at two places, one in mm/exec.c and one in mm/forkexit.c, and adds an assembly file to implement that routine to the memory manager. On my Centris 610 I was getting 2000 dhrystones/sec with caches off on a stock 18.104.22.168 kernel; with caches enabled and my new (not even optimized!) kernel, I get around 7000. Happy, eh?
Share & enjoy,
PS - I'm guessing that this will work for 040 accelerators, and other M68000 machines using 040s. If anyone tries it, let me know, okay? :-)
The file should end in .uue - it should be called something like 040sup.uue. Notice under the "table" lines there's a line that says "begin XXX 040sup.tar.Z" - this is the name of the output file to create once it's uudecoded; the uuencoded file name should be 040sup.uue then.
macread "Disk:Path:patchfile.uue" | uud - > patchfile.tar.Z
zcat patchfile.tar | tar xvf -
Apply patches to files indicated in README, move files indicated in README to appropriate spots.
And HERE is the fix.
