BIOS and EC firmware set for the HP EliteDesk 800 G2 Tower desktop, listed as working, in an 11.0 MB RAR archive. Including the embedded controller firmware matters because a corrupted EC can prevent power-on even when the main BIOS is intact. Both images are typically written with an external programmer to their respective flash chips. Read and preserve the original contents beforehand, as they hold the serial number and system identity, and ensure each image matches the size of the chip it goes to.
