At Chassis Intrusion, use the left- or right-arrow key to choose Reset. This action changes the setting to its default, Not Detected.

NOTE: If a setup password has been assigned by someone else, contact your net- work administrator for information on resetting the chassis intrusion detector.

Video DAC Snoop lets you correct video problems that may occur when certain video expansion cards are used. The default setting, Off, improves system compatibil- ity, but may prevent some video expansion cards from working properly.

If you are using a video expansion card and problems such as incorrect colors or blank windows occur, set Video DAC Snoop to On.

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 do not have a 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 setting does not affect the operation of the keyboard itself, if a key- board is attached to the computer.
