Working BIOS image for the CTL51 and CTL53 platform, built on the Compal LA-E841P motherboard at revision 2.0 dated 2017-07-18. The name marks it as fully working, and it ships as a 4.17 MB RAR archive. Compal uses the LA-xxxxP pattern for laptop boards it builds for several brands. Extract the image and write it to the SPI flash with a hardware programmer such as a CH341A. First check that the board number and revision silkscreened on the PCB match, and back up the existing chip contents.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
