'support' for faster chips will be provided by bios updates. you could always do it manually, but some people prefer presets. like strafe said, it depends on the multiplier. if p3s had a multiplier of 20 (20*100MHz or 20*133MHz) it would work. the agp, pci and everything else would be withing spec up to 133MHz fsb. unfortunately, the cpu cannot go that high.
