I have a compaq evo D510 SFF (searched for it, not same specs)
*2GB DDR Ram
*40gb HDD (IDE)
*Intel 82845G/GL/GE/PE/GV Graphics controller (32mb)
The processor (I'm pretty sure) Is SSE2
I tried Kalyway a while ago and couldn't even get it to boot.
Then, I tried iPC, and it installed with the Voodoo and SpeedStep Kernels, but it gives me a circle with a line through it (\) on the apple logo on bootup with any boot flag.
