- I'm afraid the answer seems to be nope. Sorry. I tried to boot Linux 0.98
- on my IBM PS/2 mod 80-A21 (MCA bus with (unsupported) SCSI interface), and
- it behaved quite differently than another small clone I tried it on. It
- seems to behave correctly until it's decided the display modes, then strange
- things start hapening. Firstly, the screen blanks out after a couple of
- seconds unless you press any key, and secondly, it refuses to do anything
- else, unless you start hitting the keys on the keyboard... Lastly, the
- UNIX OS aparently gets interrupts from the Diskette driver, when it
- shouldn't.
-
- My (uneducated) guess would be that the PS/2 isn't I/O compatible with the
- average ISA/EISA architecture. Given time, I'll try to dig deeper into
- things, but since I can't really run Linux as it's supposed to be run, it's
- hard to poke about things.
