D. Video Off Method
This function serves as both a screen saver and power saver for monitors.
See the next function, Video Off After, for setting the video timer.
Blank - BIOS will only blank the monitor's screen. The electricity saved
in this mode is negligible and this function is only used as a screen saver
to prevent screen damage while the screen is on but not in use.
V/H SYNC+Blank - The system turns off the vertical and horizontal syn-
chronization ports, writes blanks to the VGA buffer and the monitor's
electron gun turns off. This function requires a monitor with Green features
in order to take advantage of the power saving function. If you enable this
function and do not have a Green monitor, the result will be the same as
if you had selected Blank. This function serves as both a screen saver and
an electricity saver.
DPMS Supported - Select this option if your video card supports the Display
Power Management Signaling (DPMS) standard (i.e., you have a monitor
that supports Green features). Use software supplied by your your video
subsystem to set video power management options.
E. Video Off After
This setting determines when the monitor enters power saving mode. As the
function name indicates, the monitor enters the power saving mode after the
chosen event expires. The Power Management function must be enabled to
use this function.
F. Modem Use IRQ
If your computer has an modem, use this function to tell BIOS which IRQ is
being occupied by the modem card. When the system is in Green mode, the
modem requires an IRQ assignment to wake up the system and perform tasks.
This assignment is compliant with the APM 1.2 specification and is to be used
in coordination with APM 1.2 compliant operating systems.
G. Doze Mode
The Power Management function must not be set to disabled to enable this
function. If no interrupts have occured and the Doze timer expires, system
will enter Doze mode. In Doze mode, the CPU clock runs at a lower speed
while all other devices operate normaly.
