Working BIOS for the Dell Inspiron 5480 laptop (Dell 5480 in the name), platform CDM70, on Compal board LA-E081P at revision 2.0 (A01), dated 2017-08-08. Compal's LA-xxxxP numbering appears on the PCB silkscreen, which should be checked before writing. The 8.52 MB RAR archive is intended for flashing the SPI BIOS chip with a programmer to recover a dead or locked board. Always dump and store the original chip first, since it carries the service tag, 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.
