information.
Hyper-threading
Enable this field for Windows XP and Linux which are optimized for Hyper-Threading
technology. Select disabled for other OSes not optimized for Hyper-Threading technol-
ogy. When disabled, only one thread per enabled core is enabled.
Execute Disable Bit
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
for other OS (OS not
optimized for
Hyper-Threading
