I got a Voodoo 5500 PCI problem. Less graphically intense games like Half-Life, Anchronox, and the Windows D3D cube demo work fine, but new stuff like Serious Sam, Quake III, and Empire Earth lock up as soon as they start rendering a scene. This happens on a 810 based Celeron 700 and a KT266 based Athlon system but the card works fine on a LX based Celeron 366. The IRQ is 11 shared by ACPI Holder for PCI IRQ Steering, and I can't modify the settings. Help! Thanks.
