Firmware archive for the ASUS G531GT laptop, board revision 1.5, as an 8.29 MB RAR. The name gives no mainboard part number, so identify the board by the model and the revision printed on the PCB. The image is meant for reprogramming the SPI BIOS chip with an external programmer when the machine is dead or stuck on boot. Always read and keep a backup of the existing chip, since it may contain unique data, and make sure the file size matches 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 @sm_bios. Enginerys does not host this file.
