C1E Function
Also called “Enhanced Halt State” function. It is
improved function for Intel (R) Pentium 4
processor C1 Halt state. The operating system
will send out HLT command to the processor
while the system loading is not high. This allows
the processor to enter power-saving C1 halt
state and to reduce the loading for the
processor. Basically, C1E function is very
similar to C1 Halt State. The difference is C1E
function can lower down the processor’s
voltage and clock rate. C1E function together
with EIST can provide a better energy-saving
environment for the processor.

Execute Disable Bit
This BIOS feature is actually a toggle for the
processor's Execute Disable Bit feature. In fact,
the acronym XD is short for Execute Disable
and is specific to Intel's implementation. AMD's
implementation is called NX, short for No
Execute.
When enabled, the processor prevents the
execution of code in data-only memory pages.
This provides some protection against buffer
overflow attacks.
When disabled, the processor will not restrict
code execution in any memory area. This
makes the processor more vulnerable to buffer
overflow attacks.
It is highly recommended that you enable this
BIOS feature for increased protection against
buffer overflow attacks.
