ThinkPad P1 BIOS dump for types 20MD and 20ME, marked for type 20ME, with version n2euj22w, as a 16 MB .bin file. No board number appears in the name. Flash it with an external SPI programmer to repair a board that will not post or has corrupted firmware. A 16 MB image fits only a 128 Mbit chip, so check the flash part before writing; dumps of a different size belong to another chip. Back up the original, which holds machine-specific serial data.
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 @vinafix_bios. Enginerys does not host this file.
How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
