Firmware package for the ASUS X555UJ laptop mainboard, revision 2.0, in the variant fitted with an Nvidia GeForce 940MX discrete graphics chip. The RAR archive is about 3.6 MB and presumably holds a BIOS image intended for the onboard SPI flash. It is useful when a unit fails to post or loops after a bad update and the chip must be reprogrammed externally. Match the board revision and the GPU variant before writing, and dump the existing chip as a backup so the original serial and settings are not lost.
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 →
