Firmware dump for the HP EliteBook 820 G4 Notebook, packed into a 7.75 MB RAR; the name gives no ME, version or tested status information. It can be used to recover a 820 G4 board whose BIOS is corrupt or missing, programming the image into the SPI chip with a clip and a CH341A-type tool. Make a backup read of the chip first, check that the file length matches the flash capacity, and restore the unit's serial and DMI data afterwards where required.
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 @biosfilebins. Enginerys does not host this file.
