A BIOS dump for the Dell Latitude E7270 and E7470, both built on mainboard LA-C451P, with AAZ50 shown as the board's codename prefix. LA- numbers follow the Compal pattern, so Compal is the ODM behind this board. 4MATIC is the uploader's own tag. The 16 MB image suits a 128 Mbit SPI flash and is used to recover boards with corrupted firmware by writing the chip with a programmer. Check that the LA number printed on the PCB matches, and save the existing chip contents first.
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 @biosfilebins. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
