BIOS package for the Dell Precision 7520 and 7720 mobile workstations, on the CAP10 motherboard LA-E321P, revision 1.0 (A00). LA-E prefixed numbers belong to Compal, which builds these boards for Dell. The 8.63 MB RAR holds the firmware used to rewrite a corrupted SPI flash chip with a programmer. Confirm that the LA number and revision printed on the PCB match before use. Back up the original chip, since it carries the machine's service tag and system data, and make sure the image size fits 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.
