Hello,
Perhaps mine is a different issue but I ran into this today.
I loaded FreeBSD 7.1-RELEASE from a DVD onto an Apple Mac Pro after
partitioning a drive with bootcamp. The install went quite well and the
machine came up with no issues. I configured networking, X, and got gnome
working. I setup cvsup and loaded the STABLE sources, ran make buildworld,
make kernel, etc...
I attempted to boot into single user to run mergemaster, installworld, etc..
But the machine will not boot, I now get the following errror and prompt:
Trying to mount root from ufs:/dev/ad9s1a
Manual root filesystem specification:
<fstype>:<device> Mount <device> using filesystem <fstype>
e.g. ufs:da0s1a
? List valid disk boot devices
<empty line> Abort manual input
I input ufs:/dev/ad9s1a to no avail and ? Does not list any other devices.
I've booted from the DVD and gone into Fixit mode and can mount /dev/ad9s1a
just fine. I thought that I'd try putting back loader.old on the off chance
that might solve the problem but, I do not see a loader.old, just loader.
The kernel.old directory is there.
Any ideas on what the issue might be and how to fix?
Appreciate the help as I'd like to get 7.1-STABLE running on this machine.
Regards
John
