BIOS firmware collection for the HP ProBook 440, 450 and 470 G1, from the Wistron-built version of these notebooks; the name gives no board number or revision. The 3.76 MB RAR is meant for SPI flash recovery when the laptop will not POST or the firmware is damaged. HP sourced these models from more than one ODM, so first confirm that your board really is the Wistron design. Note the Wistron board number printed on the PCB, save a full read of the original chip, and make sure the image size matches the flash device before 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 →
