Description
Select whether to enable the Intel Execute Disable Bit Technology.
XD Bit is a hardware-based security feature that can reduce
exposure to viruses and malicious-code attacks and prevent
harmful software from executing and propagating on the computer
or network.
ASF is short for Alert Standard Format. When enabled, the ASF
controller will be activated and allowed to communicate with a
remote management server.
When enabled, some or all of the memory between the 2 GB and
4 GB limits to addresses above 4 GB. This is a workaround for the
PCI hole or PCI memory hole which is a limitation of 32-bit hardware
and 32-bit operating systems that causes a computer to appear to
have less memory available than is physically installed.
Note: This feature is useful for systems running on 64-bit OS and
those 32-bit systems that support the Physical Address Extension
method.
