Remember the system when cold/off, does post and run up
until the point where it locks up. This means it does read
and run the bios from the EPROM, but is then instable.

Unplugging the EPROM would make this much impossible, so
based upon what the system could do, but then where it
stopped, we have eliminated some things.
