Tested BIOS for the CSL50-CSL52 platform on Compal board LA-E791P, revision 2.0, with a date of 2017-04-20 in the name. The RAR archive is 11.1 MB, so it may contain more than one file; review the contents before programming. LA- numbers follow Compal's scheme, and Compal builds boards for several laptop brands. Use it to reprogram the SPI flash with an external programmer, but first read and keep a copy of the original chip and make sure the image size matches the flash capacity.
