* COMMENT: MVMEPPC machines |
| 31 |
* |
| 32 |
* This is for experiments with NetBSD/mvmeppc or RTEMS. |
| 33 |
* (ftp://ftp.netbsd.org/pub/NetBSD/arch/mvmeppc/snapshot/20020302/README) |
| 34 |
* |
| 35 |
* Note: MVME machines that really adhere to the PReP standard should be |
| 36 |
* in machine_prep.c instead. |
| 37 |
* |
| 38 |
* |
| 39 |
* TODO: This is mostly bogus. |
