1.0 Introduction
The Display Power Management System (DPMS) Screen Saver is a Terminate and
Stay Resident (TSR) program that allows you to use the energy saving
features of a monitor that conforms to the VESA Display Power Management
Signalling Proposal. This proposal is designed to work in conjunction with
other power management standards such as the U.S. Environmental Protection
Agency's Energy Star Computer program in reducing PC power consumption after
an extended period of inactivity from the user. The power management states
are designed to follow the Microsoft/Intel Advanced Power Management standard.
The three power management states are known as Standby, Suspend and Off.
Standby represents a state of minimal power reduction. Suspend represents
a state with a significant reduction in power consumption. Off represents
the lowest level of power consumption.
If you do come across any problems, please report them as soon as
possible by fax or CompuServe to ATI, using the attached form.
2.0 Requirements
- ATI Accelerator Card:
DPMS will run on all mach32 based cards.
- System:
DPMS requires at least a 286-based or higher computer running
at least DOS 2.0 or greater. The display monitor must comply
with the VESA Display Power Management Signalling proposal.
3.0 Installation
When you run the INSTALL Program on Disk 1 and select the "Install Video
Adapter Utilities", DPMS.COM is automatically copied to the \MACH32
subdirectory. Start the program by typing "DPMS" followed by zero or
more options at the DOS command line prompt. See the following section
for details regarding the various options that are available for DPMS.
4.0 Using DPMS
To use the screen saver, simply type "DPMS" at the DOS prompt. Type
"DPMS HELP" to get an overview of the commands that DPMS recognizes. The
program is case insensitive so keywords can be entered in upper or lower
case. Keywords and parameters must be separated by at least one space or
tab character, e.g. "DPMS STBY 5" is fine, but "DPMS STBY5" will generate
an "unknown parameter" error.
Typing DPMS with no options will load the TSR with default timer settings.
If the TSR is already loaded, typing DPMS with no options simply displays
the current timer settings; the timers are not adjusted.
If any timer keyword is specified, all timers that are not specified are
automatically disabled. For example "DPMS STBY 5" will set the Standby
timer to 5 minutes and disable the Suspend and Off timers. In other words,
the screen saver will only go into standby mode; it will never go into either
of the other two modes. To set all three timers, specify them all on the
command line e.g. "DPMS STBY 5 SUSP 10 OFF 15".
The following options are recognized by DPMS. These options may appear in
any order, although specifying HELP or UNLOAD will cancel all other options:
STBY {number of minutes} - Sets the standby timer. After the specified
number of minutes has elapsed with no keyboard activity, DPMS puts
the monitor into Standby mode.
SUSP {number of minutes} - Sets the suspend timer. After the specified
number of minutes has elapsed with no keyboard activity, DPMS puts
the monitor into Suspend mode.
OFF {number of minutes} - Sets the off timer. After the specified number
of minutes has elapsed with no keyboard activity, DPMS puts the
monitor into Off mode.
MOUSE {IRQ line} - Normally, DPMS only monitors the keyboard for activity.
Specifying the MOUSE option tells DPMS to also monitor mouse
activity on the specified hardware interrupt line. This option can
only be specified when DPMS is loaded the first time, and cannot be
changed when DPMS is already resident: Unload DPMS first if you
want to change this value.
QUIET - Supresses the normal messages that DPMS displays when called. This
option is useful in batch files.
UNLOAD - Unloads DPMS from memory.
HELP - Displays a usage message and then exits, no other action is done.
5.0 Errors
- DOS:
If DPMS is loaded and you receive the message "DPMS unable to unload
itself." when you attempt to unload DPMS, it is likely another TSR has
been loaded after DPMS. Try unloading the other TSR first and then
attempt to unload DPMS again.
- Microsoft Windows 3.0, 3.1:
The DPMS DOS TSR does not run under Windows. When Windows 386 enhanced
mode is started up, DPMS "goes to sleep" by disabling its internal
timers and resumes operation when you exit Windows. Alternatively, you
may want to unload DPMS before starting Windows. If you start Windows
in Standard or Real (Windows 3.0 only) mode you MUST unload DPMS first
as Windows intercepts most of the keyboard and mouse activity that DPMS
monitors and thus is unable to function properly. However, a DPMS
option is available in the mach FlexDesk Control Panel. See the FlexDesk
Control Panel help display for more information.
