Ok a followup. Linux PPC 2000 CD has a 1.3 mb PDF USER Guide that is nicely written and even has a chapter on how to use open firmware on the different machines. It even lists the Umax S900 and J700 machines and most others. From a quick read it does look like the Twin Turbo Video card is needed as that is what they list as working.i was using the twin turbo card at the time I did the install so no wonder it worked. Just dumb luck ;-) Also software called "Boot Variables" is used or "Multibooter" (available from Apple it says) to get into Open Firmware. I can send a copy of the PDF file and "Boot Variables' if you want. Let me know and give me an email address. Will S -- SuperMacs is sponsored by <http://lowendmac.com/> and...
