Tested BIOS dump for a laptop mainboard numbered LA-G902P, revision 1.0, for an 8 MB flash chip, in a 5.64 MB RAR. LA-xxxxP is Compal's numbering, so the laptop brand is not stated and must be identified separately. The image is written to the SPI chip with an external programmer to repair corrupted firmware or no-POST conditions. Since it targets an 8 MB chip, confirm the chip capacity, match the PCB revision and back up the original contents before erasing.
