Working BIOS for the ASUS E406MA laptop, mainboard revision 2.0, fitted with an Intel N4100 processor and Intel HD integrated graphics. Stored as a 5.83 MB RAR file, it is intended for restoring a corrupted or blank SPI flash. Program it with an external programmer such as a CH341A or RT809 after reading and saving the original chip contents. Compare the image size with the flash capacity, and confirm that the board revision and CPU variant match, because a mismatched dump may fail to boot or may lose the serial data.
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.
