PS/1 2133/2168 Patched ROM

Leave a reply

Dumped from a PS/1 2133-540, 486SX-25, VLB CL-GD5424
IBM P/N 65G9498, dated 21/11/93

Compatible with PS/1 2168 models with the same system board, like the 2168-552.

Modified by Major Tom (https://www.ardent-tool.com) to fix and enable the internal and external system caches when a 486 DX4ODP75 or DX4ODP100 CPU is installed on the CPU upgrade socket.

IBM PS1 2133-540 – ROM (65G9498) TOM 1.0.zip

Thanks Roman (Epictronics) for the dump.
Watch his video on YT about the restoration and upgrade of an IBM PS/1 2168 for more information.

EDIT: I’ve tested this ROM on my spring ’93 PS/1 2133-451 (mainboard P/N 52G2968) which has a VLB Cirrus Logic GD5426 graphics adapter and it seems to work correctly with a DX4ODP75.
