Firmware archive for the Compal LA-6221P motherboard, about 790 KB in RAR form, with no brand, model or version in the name. Because Compal supplies boards to several laptop makers under its LA-xxxxP numbering, the board number on the PCB is the key reference here. The contents are normally a BIOS image to be written into the SPI flash with a programmer to recover a board that is dead or stuck on a blank screen. Back up the original chip before flashing, and verify that the image size matches the chip.
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.
