I did have a problem with the USB keyboard not responding to typing (num
lock
seemed to cause the light to toggle on/off) I'll have a try with your
suggestion
about clobbering the raid autoconfig. I will want to reconfigure the
raid on the
 system at some point anyway as I seem to have performance problems so
if I have
to start again its no real problem...

Cheers,
Dave
