Firmware archive for an HP Pavilion 20 All-in-One built on the IPISB-AB motherboard, with revision 1.02 given in the name. The 3.17 MB RAR should hold a BIOS image for the system flash chip. It is used to restore a unit that powers on without image or loops at boot because of damaged firmware, by writing the SPI chip with a hardware programmer. Confirm the IPISB-AB marking and revision on the board, save a copy of the existing chip contents and match image size to the installed chip.
