IV. BIOS SOFTWARE
Video Off Method (V/H SYNC+Blank)
This field defines the video off features. The following options are available: V/H
SYNC+Blank, DPMS Standby, DPMS Suspend, DPMS OFF, DPMS Reduce ON,
and Blank Screen. The default setting, V/H SYNC+Blank, blanks the screen and
turns off vertical and horizontal scanning. 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 (use this for monitors without
power management or "green" features. If set up in your system, your screen saver
will not display with Blank Screen selected).
Suspend Switch (Enable)
This field allows you to Enable or Disable the SMI connector on the baseboard. This
connector connects to the lead from the Suspend switch mounted on the system case.
Doze Speed (div by) (8) / Stdby Speed (div by) (32)
These two fields set the CPU speed during each mode. The number indicates what
the normal CPU speed is divided by.
PM Timers (Disable)
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 Mode, Standby Mode and
Suspend Mode.
The system automatically "wakes up" from any power saving mode when there is
system activity, such as when a key is pressed, 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 pe-
riod of inactivity. This time period is user-configurable at 1–15 Min or Disable. This
feature does not affect SCSI hard drives.
Doze Mode, Standby Mode, and Suspend Mode set the period of time after which
each of these modes activate: 1 Min, 2 Min, 4 Min, 8 Min, 10 Min, 20 Min, 30 Min,
1 Hour, 2 Hour, and 4 Hour.
PM Events
This section sets the wake-up call of the system. If activity is detected from any enabled
IRQ channels in the left group, the system wakes up from suspended mode. You can
enable power management for IRQ3–IRQ15 individually in the list at the right side of
the screen. The power management feature will work on the enabled IRQ channels.
NOTE: A Microsoft serial or compatible mouse will use either COM1 (IRQ4) or
COM2 (IRQ3), and a PS/2 mouse will use IRQ12. If you know which IRQ your
mouse is using, you can enable the wake-up Event for that IRQ here and the system
will wake up when you move the mouse or click its button.
.......................................................................................................................................
IRQ3 (device) to IRQ15 (device)
You can individually Enable or Disable each IRQ to include in the sleep function.
IRQ8 (RTC Alarm) is usually set to Disable so that any software alarm clock or
event calendar can wake up the system.
