BIOS archive for the HP ProBook 455 G1, 2.55 MB RAR, whose name mentions DMI data and Wistron board 12240. HP commissioned Wistron to build this ProBook generation, and the 12240 code is a Wistron board reference. The DMI tag suggests the dump carries system identification such as serial and model data, which may need editing to match the unit being repaired. Save the original chip contents before writing, and confirm the image size equals the flash chip capacity.
