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
