10 | * Although this looks similar to an romvec for a OpenProm machine, it is | |
11 | * actually closer to what was used in the Sun2 and Sun3. | |
12 | * | |
13 | * V2 entries exist only in version 2 PROMs and later, V3 in version 3 and later. | |
14 | * | |
15 | * Many of the function prototypes are guesses. Some are certainly wrong. | |
16 | * Use with care. | |
