in the Options List.
HDD Acoustic Mode • 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.
Security This section displays available system security options.
DEP (Execute
Disable)
• 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.
Admin Password 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.
System Password Displays the current status of the system's password security feature and
allows a new system password to be assigned and verified.
Password Changes 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.
