Compressed BIOS package whose name points to a 5420 model with an 11th generation Intel processor; no brand or board number is given, so the exact laptop must be confirmed independently, likely by comparing with the label and PCB. The archive is 9.55 MB and presumably holds a flash image for SPI programming. Before relying on it, match the board number printed on the motherboard, check that the image size equals the flash chip capacity, and keep a full backup of the original contents in case the dump does not suit.
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 @jdbios_world. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
