Execute Disable Bit
This field is used to enable or disable execute disable bit. When this field is
set to Disabled, it will force the XD feature flag to always return to 0. XD can
prevent certain classes of malicious buffer overflow attacks when combined
with a supporting OS (Windows Server 2003 SP1, Windows XP SP2, SuSE
Linux 9.2, RedHat Enterprise 3 Update 3).

Limit CPUID Maximum
The CPUID instruction of some newer CPUs will return a value greater
than 3. The default is Disabled because this problem does not exist in the
Windows series operating systems. If you are using an operating system
other than Windows, this problem may occur. To avoid this problem, enable
this field to limit the return value to 3 or lesser than 3.
Enabled for Windows XP and
Linux (OS optimized for Hyper-
Threading Technology) and
Disabled for other OS (OS not
optimized for Hyper-Threading
Technology).
