BIOS firmware for the HP Pavilion 23-b102er all-in-one, which uses the IPISB-AB mainboard, a Pegatron board code. The 3.88 MB ZIP should contain an SPI flash image for restoring a desktop that has no POST or a corrupted BIOS, written with a programmer such as a CH341A. Before you program anything, compare the board label against IPISB-AB and read the original chip into a backup file. Also check that the image size matches the flash chip capacity, or the write will fail or brick the board.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
