BIOS image for the HP 15 r216tx with the Compal motherboard LA-B972P, packed as a 4.35 MB rar archive. Compal LA- numbering identifies the board design, and HP 15 models were produced on several different boards, so the code matters more than the model name. The firmware is flashed with an SPI programmer to fix corrupted BIOS, boot loops or no-display faults. Open the rar with a standard archiver, confirm the LA number on the PCB, save the original chip content and verify the image size matches the chip.
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 @bios_laptop. Enginerys does not host this file.
