To reset the Detected setting, enter the System Setup program during the system’s power-on self-test
(POST). Highlight the Chassis Intrusion option and press the left- or right-arrow key to choose Enabled,
Enabled-Silent, or Disabled.
NOTE: When the setup password is enabled, you must enter the setup password before you can
reset the Chassis Intrusion option.
DAC Snoop
DAC Snoop lets you correct video problems that may occur when certain video add-in cards are used. The
default is Off. If you are using a video add-in card and problems such as incorrect colors or blank windows
occur, set DAC Snoop to On.
ACPI
This option controls the operation of the system’s Advanced Configuration and Power Interface (ACPI)
feature.
When ACPI is set to On, momentarily pressing the power button places the system in a power-saving mode.
To turn the system off completely, press the power button for more than 4 seconds. When ACPI is set to On,
interrupt request (IRQ) line 9 is not available for use by an expansion card.
When ACPI is set to Off, momentarily pressing the power button turns off the system completely. With this
setting, IRQ9 is available for use by an expansion card.
Keyboard Errors
Keyboard Errors enables or disables reporting of keyboard errors during the POST, which is a series of
tests that the system performs on the hardware each time you turn on the system or press the reset button.
This option is useful when applied to self-starting servers or host systems that have no permanently attached
keyboard. In these situations, selecting Do Not Report suppresses all error messages relating to the
keyboard or to the keyboard controller during POST. This option does not affect the operation of the
keyboard itself if a keyboard is attached to the computer.
System Password
System Password displays the current status of your system’s password security feature and allows you to
assign and verify a new password. No one can assign a new password unless the current status is Not
Enabled, which is displayed in bright characters.
The settings for the System Password option are:
Not Enabled (the default)
Enabled
