BIOS firmware for the HP Envy 23 TouchSmart all-in-one, based on the IPISB-NK mainboard revision 1.05, stored in a RAR archive of about 3.01 MB. IPISB-NK is a Pegatron board designation, Pegatron being the ODM for this HP AIO. The image is meant for recovering a dead or bricked board by writing the SPI flash with an external programmer. Before writing, read and archive the original chip, confirm the dump size equals the chip capacity, and check the board revision on the PCB.
