edit : sorry HMJ.. I guess I didn't really read your post very well..
you want to learn more about modifying/programming them..
I would recommend you go find a few of the forums that a guy named honeyx
posts at and ask him.. he makes some awesome bios mods for ECS mobos.

look here in google for the forums he posts at.. he might be nice enough to give you some pointers.
good luck..
