IV. BIOS SOFTWARE

Video Off Option

This field determines when to activate the video off feature. The settings are Susp, Stby-> Off (default), suspend -> off, always on, and all modes -> off.

Video Off Method

This field defines the video off features. The first option V/H SYNC + Blank, which is the default setting, blanks the screen and turns off vertical and horizontal scan- ning; DPMS (acronym for Display Power Management System) allows the BIOS to control the video display card if it supports the DPMS feature; Blank Only only blanks the screen. Use the latter for monitors that do not support the “Green” fea- ture.

Take note that a screen saver software does not work with this feature. While the monitor is shut off, this software cannot display.

Suspend Switch

This field enables or disables the SMI connector on the motherboard. This connector connects to the lead from the Suspend switch mounted on the system case. Default setting for this field is Enabled.

Doze Speed, Stdby Speed

These two fields set the CPU speed during each mode. The number indicates what the normal CPU speed is divided by.

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 system 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 shuts down any IDE hard disk drives in the system after a period of inactivity. This time period is user-configurable to 1-15 Mins or Disable. This feature does not affect SCSI hard drives.

The Doze Mode, Standby Mode, and Suspend Mode fields set the period of time after which each of these modes activate. At Max Saving, these modes activate sequentially (in the given order) after one minute; at Min Saving after one hour.
