Stealth 64 Series                                            README.TXT
=======================================================================


Release Notes
-------------
This is v2.04 of the Stealth 64 Series Windows v3.1 Driver disk.

Changes in v2.04
----------------

* Added support for the VLB version of the Stealth 64 Video VRAM.


Windows Installation Notes
--------------------------
Use the INSTALL program to install the Windows 3.1 drivers from DOS
or from the Windows Program Manager.

*  Suggestion:  If you are upgrading from a previous version of the
   Diamond InControl Tools, you should install from DOS, not from
   within Windows.  This will bypass errors regarding any files that
   may be in use and cause the installation to fail.
                  
*  Suggestion:  When running the Windows install, use MS VGA
   to eliminate any OEM files that could create a conflict.

*  When running a windows install, if the install says 
   "file in use, abort/continue" and the file in question is 
   a font (*.FON) file, continue the install.

*  If strange errors occur and text is missing from dialogs,
   check for .VBX files in your \WINDOWS directory.  .VBX files
   should only reside in the \WINDOWS\SYSTEM sub-directory.

Once the driver launches Windows, you will be placed in 640x480
256-color mode and prompted to select your monitor type.  Select 
the brand monitor you have, compatible type, or use the Custom 
Monitor Timings to create your own configuration and custom 
screen centering.

*  Icon fonts are controlled by InControl Tools.  When changing
   modes back to VGA or a non-Diamond driver, these settings
   still remain.  To change back to default icon font, search
   the WIN.INI file for the IconTypeFace, IconTypeStyle, and
   IconTypeSize lines.  Place a semicolon (;) in front of these
   lines or remove the lines entirely.

*  Only resolutions that have been selected as supported in the
   Display module will be available in the Viewport choices.  If
   your monitor can display a resolution provided by the card,
   go to Display and select a monitor that offers that mode and
   refresh, or select Custom Monitor Timings and Add the mode.

*  If Windows only displays a single alphabetic character for the
   icon font, select a different font from the list of InControl
   Tools.  Windows may not support the font type/size requested
   in the resolution and resource size displayed.

*  If you had screen savers loaded previously, and they seem not
   to load on startup any longer, see the message at the top 
   regarding backing up important files and the limitation down
   below of LOAD= line being replaced and not appended.  This is
   a limitation of the Windows 3.xx SETUP program. This does not
   occur with the Diamond install.


Trouble Shooting Suggestions
----------------------------
All of the options listed below are to be added into a section called
[STLTH64.DRV].  This section is not created during the installation
of the Diamond drivers and InControl Tools.  You must manually add this
section.  It should be added to the end of the SYSTEM.INI.


*  If you are experiencing random lock-ups in Windows you can add the
   following line to the [STLTH64.DRV] section of the SYSTEM.INI. This
   type of lock-up may occur with applications that interrogate the
   systems memory searching for virill.

     LEAVEMMIODISABLED=1  --  This is set to 0 by default.

*  If you are encountering some lock-ups during heavy DMA transfers or
   your motherboard supports bus time-outs then you may try setting
   the following option in the [STLTH64.DRV] section of your SYSTEM.INI

     BUSYCHECK=ON  --  This is set to OFF by default.

*  If you are using Lenny Music Tunes, Microsoft Art Gallery, Small
   Blue Planet, Ocean Below, Vampire's Coffin, D-Day, all of the
   Brightstart education CD's, and other similar applications, you
   will want to add the following line to the [STLTH64.DRV] section
   of the SYSTEM.INI.  This will correct the corrupted screens you
   may experience during animation sequences.
 
     DEVICEBITMAPS=1 -- This is set to 0 by default.

   With the fix enabled you may possibly experience compatibility issues
   with other programs; one confirmed problem is with Adobe Illustrator
   v4.01.


   * IMPORTANT NOTE:  This is a problem with the way bitmaps are treated
                      by the application. This is not a deficiency in the
                      driver.  We have provided a means to correct this
                      issue, until the software vendor rectifies the problem.
                      All Edutainment vendors have been made aware of the
                      problem and are currently taking steps to correct the
                      bitmap issue.

*  Important Note for VLB Card users.  If you are experiencing problems
   entering Windows v3.1, in 640x480x8bpp, or greater you can relocate
   the Linear Address of the Stealth 64 Series.  Add the following line
   into the [STLTH64.DRV] section of the SYSTEM.INI.

     MEMADDR=xxxx --  This is set to 7C00 by default.

     Where xxxx can be only ONE of the following options:
        8000
        0100
        0200
        0400

Known Restrictions:
-------------------

 If you have a Sound card installed in your PC, you will need
 to disable the Internal Mix Manager for Incontrol Tools.  This is done
 throught the Audio button, a check box in the lower left corner marked
 "Disable Mixer" will enable/disable the mixer.

 DCI has limitations in it's abilities to maintain the pallete in 8bpp modes.
 This problem will exist in Microsoft's Encarta `95, and Comptons Encyclopdia.

 Dinosaur Safari from Creative Media.  This product does not operate properly
 under Windows, the vendor can be contacted at 503-241-1530.

 You cannot center any modes under "User Defined..." until you restart
 Windows.

 800x600x32bpp, 1024x768x32bpp, Small Blue Planet, "Runtime
 Error : Stack Overflow" when the  application is loaded.
 NOTE: This will occur with ALL 32bpp drivers.
 
 All resolutions, 16/24bpp, Paintbrush, Print to HP
 LaserJet 4 | Prints nothing.
 
 Run Landmark Speed - it will drop you to a dos prompt.
 This is a limitation of the application, if you
 run a DX2/66 in non-turbo mode, the program will work
 fine, in turbo mode the system hangs, this is a
 issue with the application itself, not the driver.
 
 Some monitors which do not support DPMS will start scrolling until
 entering into Sleep mode.
