BIOS image for the ASUS K52JR laptop, version 2.3A according to the name, with the Management Engine region cleared. Supplied as a raw 4.00 MB BIN, sized for a 4 MB SPI flash chip, so it writes directly with a CH341A or similar programmer. Read and keep the original chip content first to preserve serial and other board data. Verify the chip capacity matches the image and check the board revision printed on the PCB before flashing.
