Software archive of about 30.1 MB titled MPM HP Tools. The name suggests utilities for HP machines relating to manufacturing programming mode, a state that HP service software uses for writing system data such as serial and product information, though the exact contents are not listed. Extract the package and review the included programs and instructions before use. Run such tools only on the intended HP models, and back up the BIOS and system data first, as incorrect writes may leave a machine with invalid identification.
