"this bios has a date newer than the other one. Area 51 is completely different hardware (68020 or R3000 CPU with Atari Jaguar graphics chips) and couldnt possibly run that bios. Area 51 doesn't have a bios."
Ahh, My mistake! Not sure why I thought Area 51 had a BIOS.
Still would like to know if anyone looked at the CHD I provided with the newer date.
