BIOS dump for the HP ProBook 440 G1 (the name misspells it as Proook), board 48.4YW04.011, which corresponds to the Wistron 12241-1 design; RAR archive of 3.78 MB. Numbers in the 48.4xxxx.0xx form are Wistron PCB part numbers, with the last digits indicating the revision. The file is used to reflash the SPI chip with a programmer when the notebook is bricked. Confirm that the PCB carries the same number, back up the original chip, and make sure the image size matches the flash capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
