Hello,

I'm pretty stuck with the death of my bsd machine after attempt on upgrade
from 6.2 to 6.3. Some time ago, I successfully upgraded from 6.1 to
6.2following the steps in the manual

1) cvsup source to specific release
2) buildworld
3) buildkernel
4) installkernel
5) boot
6) mergemaster -p
7) installworld
8) mergemaster
9) boot

Now, after completing steps 1 to 5 the system won't boot and stucks at the
following prompt

bsd: Trying to mount root from ufs:/dev/ad1s1a
bsd: mountroot>

the prompt has "?" command which shows available boot devices. The only
device present there is my floppy (fd0)

I can choose to boot to loader prompt but have no idea how to recorver, and
more interesting, to figure out why that failure occurred?

Any help is appreciated.

In some 6.x versions the upgrade can go south. I had this happen on one server, and this is how I fixed it:

I downloaded and burned the release iso. I booted the system from CD, then in sysinstall, I used the emergency shell. In the emergency shell I mounted my drives and had a peek. In my case I saw there was no kernel. So I copied the kernel from the cd to my root / drive. After that I could reboot from the hard drive, and finished my upgrade.

Hope this helps.

        -Derek
