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 tech-
nology. When disabled, only one thread per enabled core is enabled.
Executive 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 Lunix 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
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 less than 3
.
