BIOS archive for the HP laptop with regulatory model TPN-C117, project AS056, on Compal board LA-B972P revision 1.0, 4.35 MB in RAR form. Boards numbered with LA- and a trailing P come from Compal, the ODM building this platform for HP. Use the dump to reprogram the SPI flash with a hardware programmer when the system shows no post or a corrupted BIOS. Before writing, read and keep the original chip contents, confirm the PCB says LA-B972P rev 1.0, and check that the file size matches the chip.
