Enables or disables the onboard PS/2-compatible mouse controller.
This setting specifies which video controller is primary when two video
controllers are present on the computer.
This setting allows you to change the front-panel back lighting to the
following colors: off, ruby, emerald, amber, sapphire, amethyst, topaz, and
diamond.
If your computer's processor supports Hyper-Threading, this option appears
in the Options List.
• 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
its 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.
This option provides restricted access to the computer's system setup
program in the same way that access to the system can be restricted with the
System Password option.
Displays the current status of the system's password security feature and
allows a new system password to be assigned and verified.
This option locks the system password field with the setup password. When
the field is locked, you can no longer disable password security by pressing
<Ctrl><Enter> when the computer starts.
