I can't find a bios update at Asus for the K8V-MX/S board. If you try flash with the 0201 bios fir the MX (no S) it refuses. My bios version is 1007.001, the reason I need it is I have a Sempron64 in it and while everything works, I get a unknown BIOS error at boot and the CPU isn't properly identified by bios or in Windows. All helpfull suggestions are appreciated.
