Raw 8 MB BIOS dump marked as tested and working, for the CSL50-52 board with Compal number LA-E791P, revision 2.0. The laptop brand is not given in the name, but the LA-xxxxP code identifies Compal as the board maker. The .bin image is meant to be written straight to the SPI flash with a programmer such as a CH341A. Back up the existing chip before erasing it, and confirm that the chip is 8 MB and that the PCB revision reads 2.0.
