is this a QDI board?
if you are unsure do not flash the bios untill you correctly identify the update needed for your model.
aida32 personal etd will identify the board click here
install it and click computer/summary
look at "motherboard name" "motherboard chipset" and "bios name"for info.
hovering your mouse over the bios info should give you a link to a update download for your board.
