- 1.0 Introduction
-
-
- The DPMS Terminate and Stay Resident (TSR) program allows you to use the
- energy saving features of a monitor that conforms to the VESA Display Power
- Management Signaling (DPMS) Proposal. This program provides DPMS signaling
- under the DOS environment. This TSR will not provide DPMS support under
- Windows. If you wish to use DPMS under Windows, use the ATI Desktop DPMS
- icon.
-
- The DPMS 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.
-
- *****************************
-
- 2.0 Requirements
-
- - mach64 Accelerator Card
-
- - System:
- DPMS requires at least a 386-based or higher computer running
- at least DOS 5.0 or greater. The display monitor must comply
- with the VESA Display Power Management Signaling proposal.
-
-
- -Monitor:
- DPMS compliant monitors ONLY. Damage may occur to non-DPMS monitors
-
- *****************************
-
- 3.0 Installation
-
- When you run the INSTALL Program on Disk #1 and select the "Utilities
- Installation", DPMS.COM is automatically copied to the Utilities
- subdirectory. Start the program by typing "DPMS" or DPMS followed by
- one or more options at the DOS 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.
-
- NOMOUSE - Normally, DPMS only monitors the keyboard for activity and will
- optionally monitor the mouse for activity only if it detects that a
- Microsoft compatible mouse driver is installed. Specifying the NOMOUSE
- option tells DPMS to ignore all mouse activity, even if a mouse driver
- is detected.
-
- QUIET - Suppresses 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 Known Problems
-
- - 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 3.1 Enhanced mode:
- 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 either open up a full screen DOS
- box or you exit Windows.
- If you wish to use DPMS under Windows, use the ATI Desktop DPMS icon.
-
-
- - Microsoft Windows 3.1 Standard mode:
- The DPMS DOS TSR (DPMS.COM) is not supported under Windows when run
- in standard mode (/s). Prior to starting Windows, change directory to
- the mach64 utilities directory and type:
-
- DPMS UNLOAD
-
- - Microsoft Windows 3.0:
- The mach64 does not support DPMS under Windows 3.0.
-
- - Screen Savers:
- DOS screen savers should not be used in conjunction with the DOS
- DPMS.COM TSR.
-
- Windows 3.1 screen savers should not be used in conjunction with ATI
- Desktop's DPMS function.
