33 * Nubus cards in Macintoshes are identified by 4 16-bit numbers:
34 * Category: What is the main purpose of this card?
35 * Type: Within this overall category, what kind of card?
36 * DrSW: What software interface does it use?
37 * DrHW: What specific hardware is it?
38 *
39 * For example, the "Toby Frame Buffer" display card is
40 * Category 3 (display)
41 * Type 1 (video)
42 * DrSW 1 (Apple)
43 * and DrHW 1 (TFB).
