Happy to report the box is now up and running with 2 CPUs. There was
indeed a BIOS setting along the lines of APIC 'Full Table' which was
not the default. HTT was disabled which is why there are 2 not 4 CPUs
Unfortunately the ISP's engineer also flashed the BIOS to the latest
release at the same time so that may also have had an effect.
Thanks for the help.
