RAR archive of 1.43 MB containing BIOS firmware for the ASUS A42F, marked ok to indicate a working dump. No board revision or version number appears in the name, so inspect the extracted image size before deciding which flash chip it suits. Typical use is recovering a board with corrupted firmware by writing the SPI chip with a hardware programmer. Save a full read of the current chip first, especially to preserve the unique data, and verify the mainboard number against the A42F.
