I haven't had to think about this in a long time, but I would expect
that telling the loader(8) where to find the root (root_disk_unit or
rootdev) should let it progress further.  You'll still need to fix
/etc/fstab, I suspect.

 I've searched the archives  found a similar problem in which the
 solution was to use dump to create a backup  do a fresh install of
 FreeBSD on the new system before restoring the backup.  If I have to
 take this route I might as well upgrade to 5.3, but I understand this
 uses a different filesystem to 4.11, so would this give problems with
 a restore from a 4.11 dump?

No.  The UFS2 restore(8) understands UFS1 dump files.

Change to different SCSI interface causes boot failure

Hi all,

I'm trying to replace the motherboard in my FreeBSD 4.11-RELEASE
server for a different one.  The old board has on-board Adaptec
AIC-7896N SCSI, the new one has on-board Symbios Ultra3 SCSI, on
bootup I get the following error -

Mounting root from ufs:/dev/da0s0a
setrootbyname failed
ffs_mountroot: can't find rootvp
Rootmount failed:6

Is there any way I can boot the drive on this new interface?

Thanks for all replies
