      Using DOS Debug commands, I have extracted three IBM PC 5150 BIOS
      versions. Come and get 'em:
      http://www.vintagecomputer.net/ibm/5150/BIOS_dumps/

      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). U33 is the BIOS, U29-32 is BASIC. For
      comparison purposes I have included a newer IBM PC.
