Slackware on a dell latitude XPI CD
I have one of these beasties, and unfortunately the dma chip in this machine is very buggy. You can get linux working on it:- I've had Redhat 6.2, 7.3, Dragonlinux (old) and Slackware 10.2 running on it. Redhat 6.2 worked flawlessly, but 7.3 and slackware 10.2 need the additional kernel parameter "ide=nodma". This turns off all dma (direct memory access) for the hard disk and CD - what you were seeing was most likely dma timeouts. That's what I had, everything ran so slowly.
It does mean that the system won't run as fast as a similar one with dma that works, but it is useable. I started with zipslack 10.2, got that working using the "ide=nodma" fix, then added X and KDE packages. Change the /etc/X11/xorg.conf file to make the default colour depth 16 bit instead of 24. Its a nice little system, and slackware seems to work well on it.
