Firmware image for the ASUS X53U laptop built on Compal board PBL60 LA-7322P, revision 1A, delivered in a 1.42 MB RAR archive. Compal LA-series boards often share one platform across several brands, so match both the board number and the revision silkscreened on the PCB before use. A technician would extract the binary and program it into the SPI BIOS chip with an external programmer when the original firmware is damaged. Always read the existing chip twice and compare the reads, then keep a backup before erasing and writing the new image.
