Yep. Like I said, "many (most?) 32-bit Pentium IV processors do not [support
the NX bit]".
I did not say "NO 32 bit Pentium IV processors" ... that would be incorrect!
:-)
As Synapse kindly pointed out, the NX bit (or technically, on Intel the XD
bit, NX is an AMD term) was introduced in the Prescott series, approx middle
of 2004. Williamette, Northwood, Gallatin, and Mobile Pentium 4s do not have
a XD/NX bit. Collectively, these pre-Prescott chips constititue the
numerical bulk of the running 32-bit Pentium IV population.
