BIOS image for the HP ProBook 640 on the Inventec board 6050A2566302, revision MB-A02, with a 16MB size, packed in a ZIP archive. Inventec, a major HP contract maker, numbers boards in the 6050A pattern followed by an MB revision. Technicians write this dump to the SPI flash with a programmer when a unit is bricked or stuck after a bad update. Check the revision against the board, and save the original chip content so serial and system IDs can be restored.
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.
How to open a .zip file
