Use any other partition. Yes, I know ccd tells you to do it, but that's almost as brain-damaged as wanting to have a partition type 4.2BSD. Partition c should always be "unused". > ccdconfig ccd0 32 0 /dev/sd0c /dev/sd1c /dev/sd2c > > newfs /dev/rccd0c > > My problem is (I assume) when I try to use disklabel -e. > > I edit the type, and change it from SCSI to 4.2BSD, and it doesn't take. > What I mean by that is, if I diskabel -e it again, the type is back to > SCSI. You can't change it from SCSI to 4.2BSD. I suspect you're changing the wrong field. The one you need is at the bottom of the disklabel output: 8 partitions: # size offset fstype [fsize bsize bps/cpg] b: 819200 0 swap # (Cyl. 0 - 50*) c: 8388608 0 unused 0 0 # (Cyl. 0 - 522*) Change this to: 8 partitions: # size offset fstype [fsize bsize bps/cpg] b: 819200 0 swap # (Cyl. 0 - 50*) c: 8388608 0 unused 0 0 # (Cyl. 0 - 522*) e: 8388608 0 4.2BSD 0 0 # (Cyl. 0 - 522*) You'll notice I've used partition e here. Change your ccdconfig line accordingly: ccdconfig ccd0 32 0 /dev/sd0e /dev/sd1e /dev/sd2e Greg -- See complete headers for address, home page and phone numbers finger grog@lemis.com for PGP public key To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
