Suspend --> Off

Monitor blanked when the systems enters the Suspend mode.

 

 

Modem Use IRQ

This determines the IRQ which the MODEM can use for Power Saving pur- poses. This mainboard has the ACPI feature designed on the board and it will “wake-up” automatically when it detects an incoming modem Ring-in signal. Before you can use the Ring-in signal to wakeup your PC system, you have to install the “External” modem to your PC system and tell the PC system which serial port connects to the modem by selecting the IRQ in this field. (Officially COM1 uses IRQ4)

Video Off Method

This determines the manner in which the monitor goes blank.

V/H SYNC+Blank

This selection will cause the system to turn off the vertical and hori-

zontal synchronization ports and write blanks to the video buffer.

 

 

 

Blank Screen

This option only writes blanks to the video buffer.

 

 

DPMS Support

Select this option if your monitor supports the Display Power Man-

agement Signaling (DPMS) standard of the Video Electronics Stan-

 

dards to select video power management values.

MODEM Use IRQ

This determines the IRQ which the MODEM can use for power saving purposes. This mainboard has the ACPI feature designed on the board and it will “wakeup” automatically when it detects an incoming modem Ring-in signal. Before you can use the Ring-in signal to wakeup your PC system, you have to install the “External” modem to your PC system and tell the PC system which serial port connects to the modem by selecting the IRQ in this field, (officially, COM 1 uses IRQ4, and COM 2 uses IRQ3)

Soft-Off by PWRBTN

Pressing the power button for more than 4 seconds forces the system to enter the Soft-Off state when the system has “hung”.

PWRON After PWR Fail

See the following table for all the options.

Off:

When the power returns after an AC power failure the system’s power is

off. You must press the Power button to power-on the system

 

 

 

 

When power returns after an AC power failure, the system will return to

Former-

the state where you left off before the power failure occurred. If the

system’s power is off when the AC power failure occurred, it will remain off

Sts:

when the power returns. If the system’s power is on when the AC power

 

 

failure occurred, the system will power-on when the power returns.
