When trying to play "Eggs Playing Chicken" in Mame, the screen switches over to a PC emulator showing a BIOS startup screen. After a few seconds I get the message "CMOS Checksum Error - Defaults Loaded". But I can't skip with F1 or go into the BIOS setup even when pressing those keys on the keyboard. Anyone know how to bypass this? I'm figuring I'll come across this for other games I just haven't tried yet.
