Removing a patch

[Omega16377]

I have been trying to patch an image as a master disk so I can run it on a debug machine.

Everytime I try to patch it, I get the message 'Error finding exe in system.cnf'

I believe that the image was already patched and I think that this is the cause, though I am not to sure...

Is there anyway I can remove this patch so that the image is clean? Or can I still patch this image and if so, how?

Thanks,

K.
