  1. Backup the BIOS before replacement. Use an SPI programmer to read the original BIOS ROM. Inside that ROM is the DMI region. Simply copying that region to the new board is faster than manually typing serials.
  2. Keep a Master USB. Create one flash drive with the HP Doctor DMI Tool All In One along with HP BIOS Update utilities. Label it clearly.
  3. Document Feature Bytes. Maintain a local text file of common Feature Bytes for EliteBook 840 G-series and ProBook 450 G-series to save time.
