This disk has both DOS and BSD magic. |

Give the 'b' command to go to BSD mode. |

The same trick works for /dev/rd/disc0/disc, for the DAC960. I don't know |
35 |
how far this can be pushed, but I suspect that it will work as long as |
36 |
partitions can be defined in the DOS table with the same dimensions as the |
37 |
partitions in the BSD disklabel. I don't think they have to be in the same |
38 |
order,, and I think that partitions in an extended DOS partition can be defined |
39 |
to match partitions in the BSD disklabel. I haven't played with any of this, |
40 |
however. It's only necessary until the system is installed far enough to be |
41 |
booted off of the target disk. I suspect, but haven't verified, that writing |
42 |
aboot to the drive will overlay the DOS partition table, and so the system |
43 |
cannot be rebooted from the LiveCD and used to work with the target disk |
44 |
once that has been done without redefining a DOS partition table (and, thus, |
45 |
clobbering aboot). |
