Hi,
I just patched a bios for the FS51 V1 board using the excellent how-to from this site.
I flashed it and it works a treat. 1440X900 no problem.
It's not at all obvious which version the one already listed is for. There's nothing the the board revision column.
Anyway the bios I've patched is the 038 version 10/01/2002 (latest bios) for the Shuttle SS51G with FS51 rev.1 motherboard.
Here it is:
fs51smod.bin
I flashed this with Winflash from XP SP3.
Hope it helps someone, this site saved my ass!
Steve
