It appears to do something 'cleverer', i.e. it checks the *actual*
processor speed that it sees.  The Intel Core2 Solo is adequate to run
DNP, the requirement is a 1Ghz processor and 1Gb of memory, the Dell has
2Gb of memory and a 1.4Ghz processor.

I first tried to lock the processor speed at 1.4Ghz, still didn't work.
However I have now got it to install, I needed to tell the guest machine
that it had one rather than two processors.
