10 | * Standalone definitions peculiar to vaxen: |
11 | * | |
12 | * The mba devices in the standalone system are addressed as | |
13 | * type(mba, 0, drive, partition) (disks) | |
14 | * type(mba, formatter, transport, file) (tapes) | |
15 | * | |
7eae043e | 16 | * The mbadrv macro gives the address of the device registers |
588445ee KB |
17 | * for the specified unit. |
18 | * | |
19 | * The uba devices in the standalone system are addressed as | |
20 | * type(uba, ctlr, drive, partition) (disks) | |
21 | * type(uba, formatter, transport, file) (tapes) | |
7eae043e | 22 | * |

23 | * The ubamem macro converts a specified unibus address (ala pdp-11) |
24 | * into a unibus memory address space address. | |
