Pair of BIOS dumps for the HP ProBook 450 G6, one locked and one unlocked, bundled in a 7.21 MB rar archive. Having both versions lets a technician compare the original locked image against the modified one used to clear a BIOS password or security lock. Flashing is done directly on the SPI chip with a programmer such as CH341A. The name gives no board number, so verify the motherboard code first, and back up the chip contents before writing either image to preserve unit-specific data.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
