I upgraded a S3000AH motherboard from BIOS v46 to latest v54. The update appeared to be successful and prompted me to power cycle to complete. I did, but now the board won't boot. No video activity and diagnostic LEDs cycle as (minus a few that cycle too fast for me to read):
A A A A (initialize?)
R R R - (Started dispatching an PEIM)
R R R G (Completed dispatching an PEIM)
- - - A (Reading configuration data from memory (SPD on DIMM))
- G R G (Configuring memory parameters in the memory controller)
R A R - (Entered EFI driver execution phase (DXE))
A A A A (initialize?)
(repeats ad nauseam)
I cleared CMOS. Same thing. I tried BIOS recovery mode using both a bootable CD and a USB (since the BIOS files are too big to fit on a DOS floppy). My boot CD didn't work and did same LED cycling. The USB made it farther--LEDs cycle differently (don't have the codes), turns on a blank video screen, but then hangs on:
A - - R (Resetting the mouse)
I have repeated several times and even left it on overnight just to ensure I was giving it long enough to flash. Alas, in the morning, still hung on A - - R. Seeing as how it allegedly hangs on the mouse, I have tried with no mouse, with a PS/2 mouse, with a USB mouse, and with both PS/2 and USB mice. Still hangs. Same with PS/2 and USB keyboards.
Any clue how to get the board bootable again?
