BIOS archive for an HP All-in-One 20 with the IPSHB-AT motherboard, revision 1.02, and a version marker ALT A009 in the name. It is used to restore a corrupted firmware on the board's SPI flash chip using a hardware programmer and clip. All-in-one boards are cramped, so locating the chip before removal helps. Read and back up the existing contents first since they include unit-specific data, confirm the board marking and revision, and check the image size matches the chip.
