BIOS image for the HP TouchSmart 300-1115uk all-in-one desktop, noted as tested OK, with App78-cf also in the name, possibly a board or version reference. Delivered as a 1.43 MB RAR, it is meant for reprogramming the motherboard flash when the PC stays dark or fails POST after a bad update. Use an SPI programmer for writing. Read the original chip first, compare the board markings, and verify that the dump size equals the chip capacity.
