BIOS archive for the X453MA laptop board at revision 2.0, a 3.15 MB RAR file. The model code matches the ASUS X453MA, though the name gives no BIOS version or tested status. Before use, confirm the revision printed near the board number on the PCB reads 2.0, since images for other revisions may not suit it. The extracted binary is meant for writing to the SPI flash with a programmer such as a CH341A. Check that the dump size matches the chip capacity, and back up the original first to keep serial and MAC data.

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 →
