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 a 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
