BIOS dump for a Dell Precision 3520 workstation laptop built on the CDP81 platform with board number LA-E153P, taken from a unit fitted with an Intel Core i7-7700HQ Kaby Lake processor. The LA-xxxxP numbering is used by Compal, the ODM that manufactured this board for Dell. The 24.5 MB RAR may hold more than one image or region, so inspect the contents before programming. Back up the original SPI chip first, match each file to the correct chip by size, and confirm the PCB number on your board.
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.
