I got Debian (Sarge, not Etch) running on my Model 80 (even with just
the 12mb of RAM). None of their boot floppies supports MCA so I ended
up doing the install on another machine (cheating, I suppose) and
compiling a custom 2.4 kernel that supports MCA, compiled specifically
for i386 (with 486 emulation). The 486 emulation proved necessary
because a lot of the base utilities aren't compiled for 386 anymore so
they would die with an illegal instruction fault :). (Guess the optimal
distro would be Gentoo so I can make sure everything's compiled for a
bare 386, but I can't imagine how long that would take.) Oh, and I had
to fix the ibmmca SCSI driver so it wouldn't kernel panic on boot.
Whew. This took a long time to get running.
(I tried the latest Slackware first, but they don't even support booting
from floppy anymore :(. I considered digging out my Slack 3.0 floppy
set but decided to try for something a little more modern.)
I have this running on a 4gb scsi drive (updated the bios on my
controller to get past the 1gb limit -- it's really hard to get a modern
linux distro, compilers, and kernel source on a 1gb disk and still have
room to compile it.). The result is a working Linux, but it's quite
slow. (That's an understatement - it takes 25% of the CPU just to run
'top'.) I'm in the middle of installing gnome on it just to see how long
it takes to start up on a 20Mhz 386 with 12mb of ram. Yes, there's
something horribly, horribly wrong with me. And if you want to torture
it: http://yahozna.dyndns.org:8080/ !
I'd rather run NetBSD on a machine like this, but they don't support the
IBM SCSI controllers at all.
