Hi again. First, I'd like to thank everyone who helped me get my minix system up and running on an AT, and I'm now going to join the ranks of minix hacks. I haven't seen any talk recently about minix being ported to PS/2's -- has anyone completed this task? Could someone send me source code or diffs to get something bootable on a PS/2? People here in our CS dept. have apparently gotten more serious about wanting to finish this port, because now I've got a desk with an AT and a PS/2 model 80 -- both completely at my disposal until this is done. So right now, the AT is running minix, the PS/2 boots DOS 4.00 off the hard disk, and all attempts to bring minix over via floppy have failed. So far, all I've *really* done is set up the AT, apply a few patches that to allow it to access a 1.44 meg floppy, and *attempt* to make a boot diskette for the PS/2. Although it did boot and I was able to check, list, and make file systems, '=' caused an immediate hang. But you all probably know that. In looking at the archives on bugs.nosc.mil, I saw a few patches to bios_wini.c and floppy.c for the PS/2, but nothing in kernel/main.c, i8259.c, or anything that appeared like it would solve the interrupt problem at all, at least enough to get a floppy-only minix running on a PS/2. I'm in the unique situation of having next to no documentation on the PS/2, but the perfect environment to do this port. Any help would be muchly appreciated.
