Hi Jeremy, Thanks for the clarification...at the moment I am trying to set a boot manager on my disk but am unsure which slice to set as the default boot selection when using the boot0cfg command. boot0cfg -Bv -s? ad2 disklabel -r ad0 (on a different bsd system) gives: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 204800 0 4.2BSD 0 0 0 # (Cyl. 0 - 12*) b: 2104640 204800 swap # (Cyl. 12*- 143*) c: 117258372 0 unused 0 0 # (Cyl. 0 - 7298*) e: 40960 2309440 4.2BSD 0 0 0 # (Cyl. 143*- 146*) f: 114907972 2350400 4.2BSD 0 0 0 # (Cyl. 146*- 7298*) Am I correct in assuming that a: is slice 1, b: is slice 2, etc? If so then the slice to make bootable would be slice 3 in the following setup (which is my disk): 8 partitions: # size offset fstype [fsize bsize bps/cpg] b: 2048642 310528000 swap # (Cyl. 19329*- 19456*) c: 312576642 0 unused 0 0 # (Cyl. 0 - 19456*) e: 310528000 0 4.2BSD 0 0 0 # (Cyl. 0 - 19329*) Kind Regards Khaled > -----Original Message----- > From: owner-freebsd-hackers@freebsd.org > [mailto:owner-freebsd-hackers@freebsd.org]On Behalf Of Peter Jeremy > Sent: 04 April 2006 11:41 > To: Khaled Hussain > Cc: FreeBSD Hackers > Subject: Re: cloning a FreeBSD HDD > > > On Tue, 2006-Apr-04 11:12:03 +0100, Khaled Hussain wrote: > >Why does everyone talk about dump+restore as a pair?
