I have an older machine which has a Sparkle FX5600 (SP8831DV/256MB DDR), the screen display recently became corrupted, even in the BIOS pages.
It is dead, or might it be worth flashing the BIOS? It seems to work well enough to allow it into Windows so it hasn't failed totally.
I haven't managed to find a BIOS image for the FX5600 as it seems to have been removed as too old from most of the repositories.
Thanks,
TH.
