BIOS dump for the Lenovo ThinkCentre M72z all-in-one, tied to the PIH61F board with the Topeka code name and the 10124-3 board number in Wistron style. The raw 4.00 MB .bin image is sized for a 32 Mbit SPI flash chip, so check the chip on the board matches before writing it with a programmer. The name does not say whether the Management Engine region is cleaned or the dump is tested. Read and store the original contents first, because serial and system data in the old image may need to be carried over.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bioshub. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
