BIOS .bin 8.00 MB Shared

Firmware dump for the ASUS X401A notebook, supplied as a plain 8.00 MB binary. Nothing in the name indicates the board revision, BIOS version or whether the Management Engine region has been cleaned. The size corresponds to a 64 Mbit SPI flash, and the file is meant to be written directly to that chip with a hardware programmer when the laptop shows no POST or a corrupted BIOS. Save a copy of the original chip before flashing and verify the write afterward, as a mismatched image can 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.
