I have been trying to fix up a 7200/90 I got at a yard sale with various extras I picked up cheap. I just installed OS8 then I installed a sonnet g3/400 pci upgrade card.....worked no problem.....the tried to install an ATI rage card and the computer would not boot properly. The rage card works without the sonnet card, just can't seem to make them work together.

The mac has 90 mb ram, 2x 500mb hard drives and has the vram slots filled.

Hoping someone can help.
