Working BIOS for a board with project code CAZ00 and Compal number LA-D841P, revision 3.0 (A02), dated 2016-12-07 in the name. LA-prefixed numbers follow Compal's numbering, and the ODM builds boards for several laptop brands. The image is meant to be written to the SPI flash with a programmer when firmware corruption causes no POST, no display or a boot loop. Match the LA number and revision on the PCB, keep a backup of the original chip, and confirm the file size fits the flash device.
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.
