Diamond Computer Systems VIPER (VLB/PCI) Power Management vers. 1.2
12/29/93


Diamond Display Power Management supports three power management states
defined by VESA  (Video Electronics Standards Association, version 1.0p,
revision 0.7p, August 20, 1993) in both DOS and Windows environments:
        STANDBY
        SUSPEND
        OFF

Power management states in DOS environment can be individually set from 1
to 99 minutes through options of VIPERPM (VIPER (VLB/PCI) power management
TSR intallation program) as following:

   Usage:  VIPERPM [option]
   Options:
     h - Displays this help message
     u - Unloads utility from memory
     bxx - sets Standby timer in minutes (1 to 99) in DOS environment
     sxx - sets Suspend timer in minutes (1 to 99) in DOS environment
     oxx - sets Off timer in minutes (1 to 99) in DOS environment

   For example:

          VIPERPM b7 s15 o27 <enter>

        Viper (VLB/PCI) will be in STANDBY state after 7 minutes in DOS
        environment.  It will be in SUSPEND state 8 minutes after STANDBY
        state in DOS environment.  Then in OFF state 12 minutes after SUSPEND
        state in DOS environment.

   After Viper (VLB/PCI) power management TSR is loaded, you can use VIPERPM
   to show current power management timer settings in DOS environment.

   For example: C:\VIPERPM <enter>

While the system switches into Windows enviroment, the power management states
can be individually set from 1 to 75 minutes through DPMI windows application.

   For example:

        STANDBY=10 minutes
        SUSPEND=25 minutes
        OFF=75 minutes

        Viper (VLB/PCI) will be in STANDBY state after 10 minutes.  It will
        be in SUSPEND state 15 minutes after STANDBY state.  Then in OFF state
        50 minutes after SUSPEND state.

Display adapter is set to ON state with input from keyboard or mouse (if mouse
device driver is loaded) in both DOS and Windows environments.
