Using the System Setup Program 2-9
To specify your priority preferences, order the devices
under these categories so that the highest-priority con-
troller is at the top of the Device Controller Priority
category and the highest-priority device is at the top of
the Boot Device Priority category. Order the remainder of
the devices in the Boot Device Priority category accord-
ing to your preferences. Move any devices that you want
the system to ignore during start-up into the Exclude
From Boot Device Priority category.
NOTES: If the system boots from the network, make sure
the Intel LANDesk
®
Service Agent for 3C90X is the first
item in the Boot Device Priority list on the Device List
screen.
The system defines drive C in the Boot Device Priority
category as the first hard-disk drive attached to the high-
est-priority controller.
To change the order of the devices, press <Ctrl> and the
up- or down-arrow key. If you want to revert to the
original boot priority list settings, press <Ctrl><Del>.
NOTE: If you exit the Device List screen by pressing
<Esc> or <Alt><b> without making any changes, the
Boot Sequence category is set to the Device List option.
Setup Password
Setup Password lets you restrict access to your com-
puter’s System Setup program in the same way that you
restrict access to your system with the system
password feature. The options are:
•
Not Enabled (the default)
•
Enabled
•
Disabled by Jumper
NOTE: Read “Using the Setup Password Feature” found
later in this chapter for instructions on assigning a setup
password and using or changing an existing setup
password. See “Disabling a Forgotten Password” found
later in this chapter for instructions on disabling a
forgotten setup password.
Auto Power On
Auto Power On enables you to turn your computer sys-
tem on automatically on certain days of the week at a
preset time. You can set Auto Power On to turn on the
system either every day or every Monday through Friday.
NOTE: This feature will not work if you shut off your sys-
tem using a power strip or surge protector.
Time is kept in a 24-hour format (hours:minutes). To
change the start-up time, press the right-arrow key to
increase the number in the highlighted field or press the
left-arrow key to decrease the number. If you prefer, you
can type numbers in both of the appropriate fields.
The default for Auto Power On is Disabled.
Power Management
For certain types of monitors and most EIDE hard-disk
drives, you can reduce system power consumption by
enabling the power management feature. With Power
Management enabled, these monitors and drives
automatically switch into low-power mode during
periods of system inactivity.
Power Management can be implemented at three levels—
Maximum, Regular, and Minimum
.
(The different levels
apply to the monitor only; hard-disk drive operation is
the same for all three.) The default setting for this
category is Disabled.
Saving Monitor Power
If you have a Video Electronics Standards Association
(VESA
®
) Display Power Management Signaling
(DPMS)-compliant monitor, enabling the Power
Management category reduces monitor power
consumption during periods of keyboard and mouse
inactivity.
NOTE: The power management feature monitors activity of
a mouse connected to the Personal System/2 (PS/2)-
compatible mouse port.
By setting Power Management to Maximum, Regular, or
Minimum, you can set predefined time-out periods (see
Table 2-3) for the two successive monitor shutdown
stages, standby and off.
CAUTION: Check your monitor documentation to
make sure you have a DPMS-compliant monitor
before you enable this feature. Otherwise, you risk
damaging the monitor.
