I picked up a Performa 640CD with the infamous DOS Compatible card inside. I have verified it's there and everything looks good.
When I first booted up the machine, the OS would freeze. I decided to boot off an external disk, and copy the contents over and reformat.
Doing so, resulted in lots of lag on some files. Seems there are some corrupt files on the boot disk. No problem.
I formatted it while booted in Mac OS 7.6.1 and installed a fresh copy of Mac OS 7.5.5. Upon reboot, when it gets to PC Setup control panel, a system bomb appears with BUS Error as the message.
What would cause this, and how can I go about verifying the DOS card?
