Flashed bios and got "Error Loading Operating System." Okay when reflashed back to previous level. I post I saw (another group?) suggested that XP should be set (before the flash) to generic ide drivers. Does that make any sense? How?
Open up "IDE ATA/ATPI controllers" in Device Manager. Check if you're using an Intel or Microsoft driver. Based on the suggestion you read, if it's using an Intel driver you can roll back to the Microsoft driver.
