BIOS and EC firmware for an HP notebook, with ET866 and 94-0 in the name and two images for chip positions U9 and U21. Supplied as a 1.97 MB RAR archive. The model is not named directly, so verify the board markings before use. The EC image matters for power, charging and keyboard faults, while the BIOS restores a corrupted system flash. Write each file to its matching chip with a programmer, and read out the original contents of both chips first to keep a safe copy.
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 @biosarchive. 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 →
