BIOS image for board BM5124 version 1.3, marked in the name as tested and working, in a RAR archive. The name does not say which device it is for. Board BM5124 is linked to Xiaomi RedmiBook laptops built by BitLand, but confirm that on the PCB rather than trusting the filename. The dump is written to the SPI flash with an external programmer to revive a board with corrupt firmware. Back up the existing chip first and check that the image size matches the chip capacity.
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 @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
