system move

[Martin Vana]

Hi,
I've bought a new disk and tried to move my FreeBSD 5.1 release on it. Even I'm a real newbie I've followed all the steps from faq/disks 9.2 carrefuly /*eg.  dump 0af - / | restore xf -*/ and finally set bootable in sysinstall. All the data are there when I tried to mount it but it is still bugging me with 'invalid partition' message during boot.
Here are some data that might help you to help me:
ad1s1 and ad1s3 are just data.
/,/var,/tmp,/swp are all on ad1s2
