[ILUG] FC1 disc clone from IDE to SATA causes kernel panic at boot

[Michael Jonker]

Any help please!!

The situation is this: A PC controlling an industrial laser cutter has 
died. It has specialised proprietary drivers and software (from a 
company which is no more) compiled in - so rebuilding from fresh install 
is not an option. It was running on FC1 'Yarrow' and the IDE HDD is good 
(it was tested on an identical machine)

The approach I have taken has worked for other machines in the workshop 
previously - Clone the drive using Clonezilla and deliver a new PC box 
for the machine.

Here is the problem:

The new SATA drive clone (and the original IDE via usb) boots into grub, 
but then dies with the following error:

VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00

I am fairly sure the problem is that FC1 is looking for 'hda' and not 
'sda'. This seems to be confirmed by a few threads that I have already 
found on the internet.

Here is what I have already tried:
-I have tried modifying the root boot option (root=/dev/sda1)
-I have modified fstab and mtab in FC1 to reflect sda instead of hda
-Updated grub.conf (Anaconda) to reflect sda
-run grep for 'hda' and modified any relevant system files

Still no joy

Has anybody had a similar problem (and hopefully solution?)

Thanks in advance,
