Introduction
Thanks for using SETMODE, our utility to adjust and center
video modes on your monitor. SETMODE comes as a companion
program to VPRVESA, our VESA VBE driver for the Diamond Viper.
What are the best features of SETMODE?
* You only define the video resolution for one color depth
(8-bit); the video modes that use more colors (HiColor and
TrueColor) are automatically calculated.
* You can change just one video resolution, or multiple. It is
all menu driven and user friendly.
* You are left total freedom in specifying refresh rates.
SETMODE supports vertical refresh rates up to 120Hz and
horizontal refresh rates up to 99kHz.
* The video mode parameters are automatically updated in the
resident VPRVESA program, so you don't have to restart your
machine whenever you change a video mode.
* You can create customized video modes. If you want a
multimedia resolution of 512x486, just define it and start
using it after you have told VPRVESA that you want to use
this resolution (see the VPRVESA User's Manual).
This manual is still in its raw form. The next SETMODE version
will include a more thorough manual, describing in detail how
each parameter affects your monitor screen.
------------------------------------------------------------
Note: You must insure that the frequencies you define are
compatible with your monitor. Himalaya Software is not
responsible for any damage caused to your monitor or other
hardware if you select incompatible frequencies from within
SETMODE.
------------------------------------------------------------
Installation
If you have purchased both VPRVESA and SETMODE, you must run
the INSTALL program to copy and register both VPRVESA and
SETMODE programs. If you are using the ShareWare copy, you may
want to copy SETMODE.EXE on your fixed disk. It does not matter
where you put it, but it is a good practice to keep related
programs together, so you might want to copy the program to the
__________________________________________________________________

Choosing A Video Mode To Change
__________________________________________________________________
directory where the other Viper products are located, usually
C:\VIPER. Just type the following command at the DOS prompt:
C> COPY A:SETMODE.* C:\VIPER
in which you replace C:\VIPER with the directory of your
choice.
It is very important that SETMODE knows where to find the
VIPER.INI file, in which all monitor and video mode settings
are stored. By default, SETMODE (and other Viper utilities)
looks in the C:\VIPER directory. If there is no VIPER.INI file
there, it scans the environment for a variable named VIPERPATH.
If this variable is not found, SETMODE returns with an error
message. So, if your Viper utilities are not located in the
C:\VIPER directory, be sure to set the VIPERPATH variable in
your AUTOEXEC.BAT file:
SET VIPERPATH=C:\VIPER
Choosing A Video Mode To Change
You start SETMODE by typing
C> SETMODE
at the command prompt. After the initial registration box, it
will show the "Selection Menu". This menu lists all available
video modes in the VIPER.INI file and a "Custom Size" option.
Use the arrow keys to move the cursor to the desired video mode
and press the Enter key.
If you have selected the "Custom Size" option, you will be
asked to enter the desired screen resolution. When you have
entered the screen resolution, press the F10 key to continue.
Pressing the Esc key will exit the program.
Setting The Timing Parameters
Once you have selected the video mode to change, the timing
parameter screen will be shown. In this screen you can define
various monitor and video mode settings. Just use the arrow and
Tab keys to move from field to field.
