BIOS archive with a main image from a 32 MB top chip, with the Management Engine region cleaned. No brand, model or board number appears in the name. A cleaned ME region means the dump has been reset so it can boot on another board without carrying over ME state. Confirm the target board matches the source, check the chip capacity is 32 MB, and back up the original contents with a programmer before writing. Machines with two flash chips need the other image as well.
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 @Satale_bios_esquemas_Laptop. 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 →
