HP laptop firmware for the Wistron board 18744-1, with the name listing 085E2F10 and 086ADF10 identifiers, a 16 MB BIOS image and EC firmware. The RAR archive is 13.9 MB. Wistron boards use this five-digit-dash numbering. Program the 16 MB image to the SPI flash with a hardware programmer, and the EC file if the embedded controller needs it. Back up the original chip before writing and confirm the chip capacity matches so the image fits.
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.
