BIOS and EC firmware for the Pegatron BK5EA motherboard, revision 2.2, supplied as a 4.3 MB ZIP archive. Including both images allows recovery of the main SPI BIOS as well as the embedded controller that handles power-on, charging, battery and keyboard functions. Technicians flash these with a hardware programmer when a board shows no power or no display after a corrupted update. The revision on the PCB should match 2.2, and the original chip must be backed up before writing, since its size and region data need to match.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
