technology. Select disabled for other OSes not optimized for Hyper-Threading technol-

ogy. When disabled, only one thread per enabled core is enabled.

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 CUPID 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 operat-

ing 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 less

than 3

.

Enabled for Windows XP
and Linux (OS optimized
for Hyper-Threading
Technology) and Disabled
