It's not actually a boot disk I use, but a PXE Boot image (created with 3com Boot Services that comes with Ghost 7.5) - although I could cobble one together.
There's a couple of other things that might be causing the problem, though. How much memory have you got? Because I have been told there may be some memory issues if you have >2gb. If so, try taking out some memory so that it's 2gb or less. Also, are you using the latest BIOS updates (I know that there is also a BIOS problem when using 4gb RAM). My setup is with identical X330's, 2GB RAM all with latest BIOS updates. I am also using Ghost 7.5.
