Thanks jmattson,
The original value was
cpuidMask.val.1.ecx = 0x0298e23f = 0000 0010 1001 1000 1110 0010 0011 1111
and I changed to
0x0298e233 = 0000 0010 1001 1000 1110 0010 0011 0011
Is that what you were intending?
This should take hold without a reboot right? I found when I rebooted the value was reset.
