Original keyboard controller firmware dump for Quanta board DAR62CMB6A0, revision A, intended for the separate KBC or EC flash chip rather than the main BIOS. The 1 MB file fits an 8 Mbit chip. Faulty EC firmware can cause no-power, charging or fan problems, so technicians rewrite this chip with a programmer. Make sure you are programming the EC flash and not the main BIOS chip, match the board revision, and keep a backup of the existing data.

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