ZIP archive of about 3.58 MB containing BIOS firmware for the ASUS X453MA laptop, a Bay Trail-era model in the X453 line. The name gives no version, board revision or ME status, so open it to see whether it is a raw SPI dump or a vendor update file. Raw images are programmed onto the flash chip with a CH341A or similar programmer when the board is unresponsive. Read and keep the original chip contents, compare the board revision on the PCB, and confirm the image size equals the chip capacity.
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.
