Comments
Some computer viruses
and worms cause memory
buffers to overflow by
running code where only
data is allowed. If the
Data Execution Prevention
feature can be used with
your operating system, then
by selecting "Enabled" you
can protect your computer
against attacks by such
viruses and worms. If after
choosing "Enabled" you
find that an application
program does not run
correctly, select "Disabled"
and reset the setting.
If you select "Enabled,"
a VMM (Virtual Machine
Monitor) can utilize the
additional hardware
capabilities provided by
Virtualization Technology.
Intel VT-d is Intel
Virtualization Technology
for Directed I/O. When
enabled, a VMM can utilize
the platform infrastructure
for I/O virtualization.
