Unlocked variant of the original BIOS bin for the HP EliteBook 840 G3, archived as RAR at 7.39 MB. The name marks it as unlock, which on business HP machines typically means a dump altered to remove a BIOS password or lock; the exact change is not documented. Flash it to the SPI chip with an external programmer. Always read and keep the existing chip contents first so serial and configuration data can be restored, and verify the write after programming.

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 →
