  BIOS Dumps from IBM 5150 by Bill Degnan - 06/14/2008 15:50
Using Debug commands, I have extracted three IBM PC 5150 BIOS versions.

The numbers associated with these files correspond to their IBM 5150 serial numbers. The silkscreen markings on the ROM chips are listed below (slashes separate each line).
