I may be completely off here=2C but isn't this the NX bit problem? You
need to have the NX bit set in BIOS for the cpu_family flag to be set
correctly. =20

Mike=2C
I see NX in the cpuFlags list: ...syscall=2Cnx=2Clm=2C... is that you are r=
effering to?
Though I think it boils down to the fact that what I'm running it on is a P=
entium D=2C which is the NetBurst architecture. NetBurst is below Conroe=2C=
so it would fail to meet the cluster compatibility level of Conroe.
