I am attempting to install Netware 6.5sp7 fresh on a new Intel DG31PR

About 30 seconds into the Netware Install start -

the MediaManager assigns itself to Interrupt 6
then immediately Netware abends
with the error NB-3.01.11
goes a bit further, then freezes

I have tried changing all sorts of BIOS settings with no results.

Any ideas would be greatly appreciated. Thank you. Jim
