Set to On (default) so that USB devices will be detected and supported in
the operating system. The No Boot option enables a USB controller, but it
does not recognize a USB storage device.
This setting specifies which video controller is primary when two video
controllers are present on the computer.
Use this option to select 8 MB (default) or 1 MB of system memory for an
integrated video controller.
If your computer's processor supports Hyper-Threading, this option appears
in the Options List.
This field specifies whether Enhanced Intel SpeedStep
enabled for any supported processor in the computer.
• Bypass — Your computer does not test or change the current acoustics
mode setting.
• Quiet (default) — The hard drive operates at its most quiet setting.
• Suggested — The hard drive operates at the level suggested by the drive
manufacturer.
• Performance — The hard drive operates at its maximum speed.
NOTE:
Switching to performance mode may cause the drive to be noisier, but
the drive's performance is not affected.
NOTE:
Changing the acoustics setting does not alter your hard drive image.
This section displays available system security options.
• Opt-In (default) — DEP is enabled by default on computers with
NX-capable processors. Only Windows system binaries are covered by DEP
with this option. Applications may enable DEP protection through creating
an application compatibility shim and installing that shim with the
application.
• Opt-Out — DEP is enabled for all processes. Users can manually create
exceptions for specific applications in System Properties, or IT Pros and
ISVs can use the Application Compatibility Toolkit to opt-out.
• Always On — Full DEP coverage with no exceptions.
• Always Off — No user-mode DEP coverage. Drivers and the Widows core
kernel binaries are covered by DEP, but no other binaries are included in the
set of covered applications.
Use this option with Admin Password to unlock setup options.
NOTE:
This option appears only when the Admin Password option is enabled.
