BIOS dump for the ASUS GA503R laptop on board DANJPMB2AA0, revision A, sized for a 32MB flash chip and stored in a 6.37 MB RAR. DAxxxxMBxxx codes follow Quanta's motherboard numbering, so the board was produced by Quanta for ASUS. Write the image to the SPI chip with a programmer to fix corrupted firmware or a no-post condition. Make a full backup of the original chip first, check that the image matches the 32MB chip capacity, and confirm the board number on the PCB.
