Table 2, Power Time-Out Periods) for the two successive monitor shutdown stages, standby and off.
NOTE: Each monitor manufacturer defines the details of the shutdown stages for its own monitors. But in all
cases, power consumption decreases with each stage from "on" (full power) to "standby" (reduced power; the
display image usually disappears) to "off" (where power consumption is minimal). To define these stages for
your monitor, see the documentation that came with the monitor.
For most DPMS-compliant monitors, any subsequent activity - including moving the mouse - returns full power to the
monitor.
Check your monitor documentation for information on how your monitor is designed to operate.

Chassis Intrusion
Chassis Intrusion displays the status of the chassis intrusion monitor at system startup. Settings are:
Not detected (the default)
Detected
Reset
If Detected is displayed and you want to clear the field to allow future intrusions to be detected, use the left- or right-
arrow key to selected Reset. Not Detected indicates that the chassis has not been opened since the last time Chassis
Intrusion was reset.
Mouse
Mouse enables or disables the system's built-in PS/2-compatible mouse port. Disabling the mouse allows an expansion
card to use IRQ 12.
Serial Port 1 and Serial Port 2
Serial Port 1 and Serial Port 2 configure the system's built-in serial ports. These options can be set to Auto (the
default) to automatically configure a port, to a particular designation (COM1 or COM3 for Serial Port 1; COM2 or
COM4 for Serial Port 2), or to Off to disable the port.
If you set a serial port to Auto and add an expansion card containing a port configured to the same designation, the
system automatically remaps the built-in port to the next available port designation that shares the same IRQ setting, as
follows:
COM1 (input/output [I/O] address 3F8h), which shares IRQ4 with COM3, is remapped to COM3 (I/O address
3E8h).
