Firmware archive for a laptop board numbered LA-9752P, revision 1.0, with ZIWFS given as the board code name, in a 6.06 MB RAR file. The LA- prefix follows the Compal numbering pattern, so Compal is the board maker even though the laptop carries another brand name, which the file name does not state. Such dumps are used to reprogram a corrupted SPI BIOS chip with an external programmer. Always back up the original chip, check that image size matches the flash capacity and verify the PCB number first.
