Well, my mobo "supports" AGP 8X as well as the card does, it's a Gainward Gf-4 MX440 128Mb DDR 8X AGP,
256 DDR PC3200 (but running at 266Mhz)
AGP 8X enabled
apmd disabled at boot time
I will try setting the AGP at 2X (yuck!)
but first I'll try with Spark solution and a fresh instalation of RH9, because I had release 8 and upgraded to 9.............I'm so paranoid now that I'm starting to think that the actual position of stars and planets have a negative influence in nVidia and RedHat linux.
