I had a similar situation only a few days ago. I don't know if this is correct, or should even work, but it did for me. Just change the label from "e" to "a" using `disklabel -e ad?` (it will put you into an editor, see `man disklabel` for more details). For example, say this is your current layout (use `disklabel ad?` to get this output): [begin output] <bunch of other stuff> 8 partitions: # size offset fstype [fsize bsize bps/cpg] b: 196608 65536 swap # (Cyl. 4*- 16*) c: 8421840 0 unused 0 0 # (Cyl. 0 - 524*) e: 65536 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 4*) f: 1048576 262144 4.2BSD 1024 8192 16 # (Cyl. 16*- 81*) g: 65536 1310720 4.2BSD 1024 8192 16 # (Cyl. 81*- 85*) h: 7045584 1376256 4.2BSD 1024 8192 16 # (Cyl. 85*- 524*) [end output] Change the line which starts with "e" to "a" using `disklabel -e ad?`, so it'll look like: [begin output] 8 partitions: # size offset fstype [fsize bsize bps/cpg] b: 196608 65536 swap # (Cyl. 4*- 16*) c: 8421840 0 unused 0 0 # (Cyl. 0 - 524*) a: 65536 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 4*) f: 1048576 262144 4.2BSD 1024 8192 16 # (Cyl. 16*- 81*) g: 65536 1310720 4.2BSD 1024 8192 16 # (Cyl. 81*- 85*) h: 7045584 1376256 4.2BSD 1024 8192 16 # (Cyl. 85*- 524*) [end output] After this you're going to need to make the device entry for your new label (`cd /dev;sh MAKEDEV ad?s1a`) and you should be all set. Although I used the IDE driver for all my examples, this should also work for SCSI disks. Also, while this shouldn't touch the actual data on your disk, I strongly recommend you have a backup; just in case.
