BIOS file for an ASUS K50AF using the K40AB motherboard, revision 2.3, compressed into a 767 KB RAR. The name shows that this K50 model shares the K40AB board, a common arrangement in that ASUS family. A dump like this is written to the flash chip with a programmer to fix a notebook that stays dark at power-on. Confirm that the PCB revision reads 2.3, save the existing contents before erasing, and check that the image size equals the chip capacity.
