Working BIOS image for the MS-AAA11 board in its version 1.0 revision, compressed as a RAR archive of about 3.1 MB. It differs from the version 1.1 dumps of the same board, so revision matters. Expect a raw SPI dump meant for an external programmer rather than a vendor update utility, although the name does not confirm the format inside. Read the revision on the PCB before use, store the original chip contents as a fallback, and confirm that the dump size equals the flash capacity, otherwise it will not fit.

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 →
