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. http://www.vintagecomput...et/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). 0192562.BIN S/N 0192562 (16/64K "A" Model) U28 EMPTY U29 5700019 / IBM 1981 / XE / 8220E NM U30 5700027 / IBM 1981 / XE 8223B NM U31 MK36905N-4 / 5700035 / 2A / IBM 1981 / D MALAYSIA / 8225 U32 5700043 / IBM 1981 / XE 8220E NM U33 5700671 / IBM 1981 / XE8223B N M 0239462.BIN S/N 0239462 (16/64K "A" Model) U28 EMPTY U29 5700019 / IBM 1981 / XE / 8231B NM U30 5700027 / IBM 1981 / XE 8231A NM U31 MK36905N-4 / 5700035 / IBM 1981 / MALAYSIA / 8231 U32 MK367284-4 / 5700043/ IBM 1981 / MALAYSIA / 8230 U33 AMI 8609 MAH / S68B364 / 1501476 / IBM CORP / 1981, 1983 / PHILIPPINES 1004872.BIN S/N 10048725150 (64/256K "B" Model) U28 EMPTY U29 5000019 / AM92640PC / 34148 8347ZAP U30 AM9264DPC34149 / 5000021 / 8413FPM / IBM 1981, 1983 U31 AM9264DPL34150 / 5000022 / 8411DPM / IBM 1981, 1983 U32 AM9264DPC34180 / 5000023 / 8406YPM / IBM 1981, 1982 U33 1501476 / AM9264DPC / 34146 8340ZPP Reply
