BIOS for the Compal CSL50/CSL52 platform, board LA-E791P at revision 2.0, with a date of 18 July 2017, packed in a 5.48 MB rar. LA-prefixed numbers follow Compal numbering and appear on the PCB silkscreen. The dump restores a corrupted SPI flash with an external programmer when the board shows no display or fails to boot. Read and save the original chip first, confirm the image size equals the chip capacity, and check the board reads LA-E791P rev 2.0.
