15M - 16M

CPU Speed

CPU Speed indicates the processor speed at which your system boots.

Press the left- or right-arrow key to toggle the CPU Speed option between the resident microprocessor's rated speed (the default) and a lower compatibility speed, which lets you accommodate speed-sensitive application programs. A change to this option takes effect immediately (rebooting the system is not required).

You can also toggle between the rated processor speed and the compatibility speed while the system is running in real mode by pressing <Ctrl><Alt><\>. (For keyboards that do not use American English, press <Ctrl><Alt><#>.)

Num Lock

Num Lock determines whether your system boots with the Num Lock mode activated on 101- or 102-key keyboards (it does not apply to 84-key keyboards).

When Num Lock mode is activated, the rightmost bank of keys on your keyboard provides the mathematical and numeric functions shown at the tops of the keys. When Num Lock mode is turned off, these keys provide cursor-control functions according to the label on the bottom of each key.

Chassis Intrusion

Chassis Intrusion displays the status of the system chassis intrusion monitor. The settings for this option are Enabled, Enabled-Silent, or Disabled. The default is Enabled.

If the computer cover is removed while the intrusion monitor is set to Enabled, the setting changes to Detected, and the following message appears during the boot sequence at the next system start-up:

Alert! Cover was previously removed.

If the computer cover is removed while the intrusion monitor is set to Enabled-Silent, the setting changes to Detected, but the alert message is not displayed during the boot sequence at the next system start-up.

If the intrusion monitor is set to Disabled, no intrusion monitoring occurs and no messages are displayed.

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.
