Bizarre. I know someone with this board, that I was just advising last night to upgrade their BIOS, since they haven't since they bought it. They're not overclocking, but if the async PCI/AGP freq is "busted" in the latest BIOS version, I'm going to tell them to hold off. Thanks for the heads-up.
(Wouldn't be the first MSI BIOS upgrade that broke something, my MSI KT400 board is suffering from MSI's buggy BIOS tweaks as well. 🙁 )
