Regarding the i815(e) chipset. I believe I read somewhere that the 1/2 AGP divider (and 1/4 PCI divider) only takes effect at 133Mhz FSB (unlike the Via Apollo Pro 133a, which has the 1/2 AGP divider take effect at 124Mhz FSB). So in this case, the BIOS reporting 41 MHz PCI at 124 MHz FSB would be correct. If someone can link to an article that confirms this info, please post it.
