BIOS dump read from a Macronix MX25L640 flash chip for a board labelled DV15 MLK MB, an 8.00 MB image matching that 64 Mbit part. The name does not give the laptop brand or a board revision, so the DV15 MLK code must be checked against the PCB. Such a full-chip read typically includes the descriptor, ME and BIOS regions on Intel platforms. Program it with a CH341A or similar tool after saving the original chip, and verify the write before reconnecting power to the 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 @bios_laptop. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
