BIOS dump for the CSL50/CSL52 platform on Compal board LA-E801P revision 1.0, marked as tested and working, in a 10.7 MB RAR. The LA-xxxxP numbering belongs to Compal, an ODM supplying several laptop brands. Use it to rewrite the SPI flash with a programmer when the board shows no display after a corrupted update. Confirm the board number and revision on the PCB, save the original contents before erasing, and make sure the extracted image matches the capacity of the installed chip.
