IV. BIOS SETUP

Power Management

Video Off Method (DPMS OFF)

This field defines the video off features. These options are available: DPMS OFF,

DPMS Reduce ON, Blank Screen, V/H SYNC+Blank, DPMS Standby, and DPMS Sus-

pend. The DPMS (Display Power Management System) features allow the BIOS to

control the video display card if it supports the DPMS feature. Blank Screen only

blanks the screen (for monitors without power management or “green” features). If set

up in your system, your screen saver will not display with Blank Screen selected). V/H

SYNC+Blank blanks the screen and turns off vertical and horizontal scanning.

PM Timers

This section controls the time-out settings for the Power Management scheme. The

fields included in this section are HDD Power Down, which places the hard disk

into its lowest power consumption mode, and the Doze, Standby and Suspend sys-

tem inactivation modes.

The system automatically “wakes up” from any power saving mode when there is

system activity, such as when a key is pressed from the keyboard, or when there is

activity detected from the enabled IRQ channels.

HDD Power Down (Disable)

This shuts down any IDE hard disk drives in the system after a period of inactivity.

This time period is user-configurable from 1 Min to 15 Min or Disable. This feature

does not affect SCSI hard disks.

Doze Mode, Standby Mode, Suspend Mode (Disable)

These fields set the period of time after which each of these modes activate: 1 Min, 2 Min,

3 Min, 4 Min, 8 Min, 20 Min, 30 Min, 40 Min, or 1 Hour. The default setting is Disable.

Power Up Control

This section determines the ways the system can be controlled when it is started or

restarted, when modem activity is detected, or when power to the computer is inter-

rupted and reapplied.

AC PWR Loss Restart (Disabled)

This allows you to set how you want your system to boot up after the power has been

interrupted. Disabled leaves your system off after reapplying power and Enabled

boots up your system after reapplying power.

Ring Power Up (Enable)

This allows either settings of Enable or Disable for powering up the computer (turns

the ATX power supply on) when the modem receives a call while the computer is off.

NOTE: The computer cannot receive or transmit data until the computer and appli-

cations are fully running, thus connection cannot be made on the first try. Turning

an external modem off and then back on while the computer is off causes an initializa-

tion string that will also cause the system to power on.
