Raw BIOS image named for the ASUS X407MA, version 310, as an 8.00 MB BIN file. The size matches an 8MB (64Mbit) SPI flash chip, so it can be written directly with a programmer such as CH341A or RT809. It may be a stock firmware file rather than a dump from a specific board, so check whether it contains a complete descriptor and ME region. Always save the original chip contents before writing, and confirm your board model matches X407MA.
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 →
