BIOS dump for the ASUS X553MA laptop, with the brand misspelled in the name, packed as a 3.17 MB RAR archive. The name notes a Winbond W25Q64F flash chip, which is a 64 Mbit or 8 MB SPI part. Use the file to reprogram that chip with a programmer such as a CH341A when the notebook does not boot, loops or has corrupted firmware. Before writing, confirm the chip marking on the board matches, save a read of the original contents, and check that the extracted image is exactly 8 MB to fit the flash.
