Firmware archive for the HP Pavilion 23 all-in-one PC with board IPISB-AB revision 1.02, a board code used by Pegatron. The ZIP is 2.85 MB and is aimed at recovering the system BIOS by writing the SPI flash chip directly with a hardware programmer. Make sure the silkscreened revision on the motherboard agrees with 1.02 before relying on the file. Save a full read of the original chip first, since it holds board-specific data such as serial numbers and MAC addresses.
