That looks correct to me, though I wonder why you made a d: partition out of order in there. In FreeBSD 4.xx disklabel, you can just put a '*' in for the size and it will make a partition of all remaining unpartitioned space. I don't have a 5.xx bsdlabel handy, but would be surprised if it didn't offer that feature. You will need to be booted in such a way as nothing on that slice is mounted to be able to write the new label, I believe. ////jerry > > Regards, > -- > dave [ please don't CC me ]
