Second copy of an HP 820 G3 BIOS image with the same unexplained 301 tag, stored as a 16 MB raw binary. The model points to the EliteBook 820 G3 business ultrabook. Nothing indicates ME cleaning or tested status, so treat it as a plain chip read. Write it to the 128 Mbit SPI flash only after saving the original contents and confirming the board matches. Comparing it with the first copy in a hex editor helps reveal whether the two reads are identical or come from different units.
