BIOS image for the MSI MS-AC751 board, version 2.1, sized for an 8 MB flash chip and packed in a 4.19 MB RAR archive. MS- numbers are MSI's own board designations. The extracted file should be exactly 8 MB; a different size suggests an incomplete or mismatched dump. Use an SPI programmer to write it after reading and saving the original chip, and confirm the PCB is marked as revision 2.1, since MSI changes firmware between board versions and a mismatched image may leave the board dead.
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 →
