I have a Shuttle An35Ultra and the 11.5, 12, and 12.5 multipliers dont show up in the bios. It jumps all the way from 11 to 13. I have a Barton 2500 o/c'd to 2203 mhz right now (11x200). I think a BIOS flash would give me the multipliers, but I dont know how to go about doing it. I downloaded the an35s00g.exe file from Shuttle's website but when I open it I get something that says "Error open0". I have Windows XP Professional on a NTFS partition. What would be the easiest way to flash the bios? thanks
