I wanted to get this out there in case anyone else with this board has this issue. I was given this board a few months ago and it had some obvious failing capacitors, but it still booted into Windows when I replaced the blown power supply. So I recently got around to replacing the bad caps, and installed Windows XP on a 240 gig SSD connected to the SATA 0 port by using the CDROM on the SATA 1 port and everything went fine. It was on BIOS FC from 11/18/2003 and I decided to update it to FG dated 9/9/2004. When I rebooted after the update, it wouldn't load Windows and the message was "Error loading operating system." I tried many different things, but had no luck. I then stepped it back by flashed it to FF which was dated 8/11/2004, but I still had the same error!

I went into Standard CMOS Features and changed IDE Channel 0 Master's Access Mode from Auto to Large and then it loaded Windows with no issue.
