K50AF laptop BIOS packed as a 769 KB zip, with AS213 most likely denoting firmware version 213. The name gives no board revision. It can be used through the vendor recovery tool or written directly to the flash chip with an external programmer when the board shows no display. Before programming, dump and keep the current chip contents, verify the model sticker reads K50AF, and make sure the extracted image matches the chip capacity.
