Problems booting after new motherboard - label /1 not found

[Ben Suffolk]

Hello All,

I have been using FC4 as a MythTV box for 18 months or so now and all  
has been well. I'm not really all that upto speed with the Linux way  
of doing things, so am a little stumped with this problem.

I went on Holiday and when I came back the power supply had blown in  
the unit, and after replacing the power supply it looked like it had  
taken the mother board out with it (or maybe the motherboard took the  
power supply out, who knows). Anyway I had to put a different  
motherboard in as I could not get the same one as I had before. I now  
have an MSI K8MM3 board in, before I had a NFORCE3-A.

When I try to boot I get the following :

Booting 'Fedora Core (2.6.11-1.1369_FC4)'
kernel direct mapping tables upto ffff810100000000 @ 8000-c00

Booting the kernel.
Rd Had nash version 4.2.15 starting
mkrootdev: label /1 not found

switchroot: mount failed: 22
Kernel panic - not syncing: Attempted to kill init!

And there it hangs. I am guessing its something to do with the new MB  
having different disk controllers in it.

I have tried booting with the FC4 recover cd, and it boots. I notice  
it says, "Loading SATA_VIA driver", so I wonder if I need to get that  
driver onto my existing system? or would that already be there?

It says the following files systems were not unmounted cleanly /dev/ 
sda1 I continue anyway, it then says an error occurred trying to  
mount some of my filesystems.

It has mounted /dev/sda1 on /mnt/sysimage/boot as RW (ext2) and that  
seems to be fine and intact, its also mounted /dev/sda2 on /mnt/ 
sysimage/ as RW (this on is ext3). Again it all seems to be intact.

The other volume I have is the data volume and is JFS on LVM, this I  
guess is where the error occurred during mount so is probably not  
really an issue at the moment, as the boot and root partitions are fine.

How should I proceed so that I can get the machine to boot again? I  
hope I have given enough detailed information in this request to be  
useful.

Regards

Ben
