Morning all - new member, and semi-new to bios programming (have done some stuff with ESP's, but that's about it).

Currently researching for exactly this process - reverting a previously used HP mainboard to a state suitable for putting into a spares pool and then re-dmi when installed into a machine.
Primarily EB840 G7+G8, some 850's of the same, and potentially moving into the G9+G10 models. Business, not consumer models.

This is probably the most relevant thread to ask the question in (and thanks to any that answer)
For the purposes of refurbishing boards...
