This is a standard practice used in today's BIOS and it definately has merit.
The big BIOS vendors such as AMI and Phoenix generally sell a standard BIOS to
MB manufacturers.  However, this BIOS generally needs to be customized by the
motherboard manufacturer to run with a particular motherboard.

Is the objective of OpenBIOS to provide source code to motherboard
manufacturers that they can modify and customize for their boards or is it to
provide a BIOS that will run on an individuals PC?
