BIOS dump for a Compal-designed laptop motherboard LA-J191P, revision 0.2, with FDC55 being the Compal project code noted in the name. The 7z archive is about 9 MB and is meant for writing to the board SPI flash with an external programmer such as a CH341A or RT809H. Compal numbers its boards in the LA-xxxxP format and supplies many brands, so check the code and revision printed on the PCB, read and keep the original chip contents, and make sure the image size matches the flash capacity before programming.
