BIOS image for the Acer Aspire E5-473 on the Compal A4WAB board LA-C341P, revision 1.0. Compal is the ODM, as the LA-xxxxP numbering shows, and A4WAB is its project code. Technicians use these dumps to rewrite the SPI chip with a hardware programmer after BIOS corruption or for a no-power, no-display fault. Extract the RAR and check that the board label matches LA-C341P rev 1.0. Back up the original chip before writing, and confirm the file size suits the installed flash.
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.
