Firmware package for the HP 20-2312 all-in-one, tied to the IPPBT-PT motherboard at revision 1.02A, stored as a 3.33 MB rar archive. The board code and revision in the name help confirm you have the right image for the system board inside the unit. A dump like this is usually programmed onto the SPI BIOS chip with an external programmer to recover a board that stays on a black screen. Back up the existing chip contents first and compare the label on the PCB with IPPBT-PT 1.02A before flashing anything.
