Hi, I have just updated the BIOS on this board to the latest version of the Abit BIOS. The flash was successful and everything, but when I try to boot to Windows XP Professional, I get the blue screen. First time it gives me an error relating to the ACPI.sys file. I tried reinstalling and that keeps locking up. Any ideas? I was thinking about going back to the BIOS that I had before that was working. Does anyone have any tips to help me without doing this? Thanks in advance.
