* Although this looks similar to an romvec for a OpenProm machine, it is
* actually closer to what was used in the Sun2 and Sun3.
*
* V2 entries exist only in version 2 PROMs and later, V3 in version 3 and later.
*
* Many of the function prototypes are guesses. Some are certainly wrong.
* Use with care.
