Are you configuring the system for AGP 2.0 or 3.0, ie are you configuring dev 0.0 or 1.0? The way I had it set up, I thought, was 32MB for video, 32MB for agp, and the rest for the system, using AGP 3.0. I could very well have messed something up somewhere, though. -Corey -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
