2.0 Compatibility
__________________

This graphics-accelerator device driver is compatible with OS/2
2.11, and OS/2 Warp 3.0.

3.0 DDC Monitor Support
_______________________________________

VESA Display Data Channel (DDC) 1 and 2B protocols are supported,
allowing similarly enabled computers and operating system software
to identify the monitor and its capabilities. This device driver
automatically detects DDC monitor capabilities and sets the display
to the maximum refresh rate supported by the monitor. If, after
installing this device driver, you switch from a non-DDC monitor to
a DDC monitor or switch to a different DDC monitor, you must run the
DDC Display Setup program in the System Setup folder.

Use the following procedures when installing a DDC monitor.

1. Reset the display to the lowest refresh rate available. This
will prevent the system from attempting to display at a refresh
rate higher than that supported by the new monitor.

2. Shut down your system and install the new monitor.

3. Restart your system.

4. Select the "DDC Display Setup" icon in the OS/2 System Folder.

5. When you are instructed to do so, shut down your system and
restart it.

6.0 Installing from Diskette
_______________________________

To install the Trio32/64/64V+ device driver from diskette, do the
following:

1. If system is not in VGA mode, select VGA mode.

2. Insert the Trio32/64/64V+ diskette into drive A (or any other
diskette drive).

Note: "S3 DRV1" must be the volume label of this diskette.
To verify the label, use "Label A:".

3. Open an OS/2 full-screen or OS/2 window session.

4. At the OS/2 command prompt, type the following command to copy
all necessary files to the OS/2 drive:

A:SETUP A: C:

where A: is the diskette drive, and C: is the drive where OS/2
is installed.

Then press Enter.

5. When prompted to do so, remove the diskette from drive A,
perform a shutdown, and then restart your computer.

6. Open the OS/2 System folder.

7. Open the System Setup folder.

8. Open the Display Driver Install object or enter "dspinstl" at
an OS/2 command prompt. When the Display Driver Install window
appears, select Primary Display Driver and then select OK.

9. When the Display Driver Select window appears, select "S3
Trio32/64/64V+ [32Bit] Version 2.80.19" to install the video
driver.

10. When the Monitor Configuration/Selection Utility window appears,
the "Install Using Defaults for Monitor Type" choice is
preselected. You can accept this choice or select "Install
Using Display Adapter Utility Program" to choose a different

your display does not appear in the list, select Default.

It might be necessary to restart your computer to have all
refresh rate options available.

15. When the system has restarted:
a. Open the System object and select Screen page 1, as in step
13.
b. Select a screen resolution and a screen refresh rate.
c. Close the Settings notebook.
d. Perform a shutdown and restart your computer.

NOTES:

o During the installation of this driver, DISPLAY.LOG and
DSPINSTL.LOG files are created in the OS/2\INSTALL directory.
These files identify the OS/2 system files that were updated and
indicate whether the installation was successful. The contents
of these files might be useful if you need to report an
installation problem to IBM.

o If the video memory size is changed after the device driver is
installed, the device driver must be reinstalled in order for
the system to recognize the change. Not reinstalling the driver
might result in serious system problems.

7.0 Installing in a CID Environment
______________________________________

NOTES:

o The server must contain a directory named S3_DRVS on the same
drive where the OS/2 diskettes reside. The S3_DRVS directory
must contain all of the files from the Trio32/64/64V+ device driver
diskette.
o OS/2 must have been successfully installed on the client using
the CID (Configuration Installation Distribution) method.

To install the Trio64/64V+ graphics-accelerator device driver
using CID, use the following information to modify your LCU command
file.

NOTE: The following information is meant as a guide.
Your LCU command file might be different.

Following is an explanation of the line that is
executed in the LCU command file:

C:\OS2\INSTALL\DSPINSTL /pd:c:\os2\install\TRIOV1.dsc
/S:X:\img\s3_drvs /T:C: /res:640x480x256 /u

/pd:c:\os2\install\TRIOV1.dsc
is the dsc laid down during setup phase.

/S:X:\img\s3_drvs
where X:\img\s3_drvs is the redirected source path.

/T:C:
where C: is the drive where OS/2 is installed.

/res:640x480x256
is a resolution/color depth from the list of "Supported
Resolutions" that appears earlier in this README.

/u
means Unattended installation.

NOTES:

o Be sure you have the stated video memory required, as listed
in "Supported Resolutions" earlier in this README. A safe
choice is 640x480x256. Any of the listed resolutions can be
selected, but your display might be damaged if you select a
resolution that your display does not support.

o After the Trio32/64/64V+ device driver has been successfully
installed on the client machine using the CID method and the
client machine is restarted, the resolution will be as specified
by command line argument.

o After the CID installation, refer the end user to section 6.0
"Installation from Diskette," step 12.

8.0 Selecting Small or Large Fonts for Windows
_______________________________________

The default font sizes for Windows sessions are listed below.

Resolution Default Font Size
---------- ---------------------------
640x480 Small
800x600 Small
1024x768 Large
1280x1024 Large
1600x1200 Large

NOTE: Large fonts are not available for 640x480 resolution.

Use the following procedures to select small or large fonts
for Windows sessions.

1. Select the "S3 Windows Font Size" object in the OS/2 System
Setup Folder.

2. Click on the radio button next to the font size you wish to
select.

3. Click on the OK button.

4. A message will display saying that the new settings will take
effect the next time you restart your Windows session.
Currently open sessions will not be affected by the new
settings.

5. Click on the OK button.

6. Start any WIN-OS/2 window or full-screen session.

The setting you select will remain in effect until you explicitly
change it, you change your display resolution, or you install a new
display driver.

9.0 Features and Fixes Included in this Driver
_____________________________________________

- "System - Settings" notebook support for setting refresh rate
- DDC monitor detection support
- Windows "Large font" and "Small font" support in high resolutions
- WIN-OS/2 based on latest S3 Windows 3.1 drivers
- One-diskette package

10.0 Limitations
_______________________

1. CID install pauses due to SVGA.EXE loading in the background.
Workaround: In the CID install script, do not initiate any other
processes until DISPINSTL completes execution. Ensure that no
other processes are running during CID install. This can be
accomplished by adding the following line to the CONFIGSYS_LINE
keyword of the CID response file:

SET RESTART_OBJECTS=STARTUP_FOLDERS_ONLY

2. During CID install of IBM AntiVirus when using NetView DM/2,
the OS/2 full screen is displayed as a black screen.
Workaround: Perform CID install under VGA.

3. DSPINSTL does not allow CID selection of monitor and refresh
rate. The workaround is as follows:

Requirements:
* A system with the same graphics card and monitor configured with the
S3 driver version 2.80.19, the correct display type,
the desired resolution, and the desired refresh rate.

Step 1: Copy Configured Video/Display Data Files
* copy the video and display data files containing information about
the display type, resolution and refresh rate to the CID server
(\img\svgadata).

> copy \os2\svgadata.pmi x:\img\svgadata
> copy \os2\video.cfg x:\img\svgadata

Step 2: Create CID Command File
* create a command file to copy svgadata.pmi and video.cfg to the
client system's \os2 directory via CID.
* reboot the client system.
* the client system will be configured with the correct driver,
display type, resolution and refresh rate.

4. Some programs, such as WINBENCH95, WINBENCH96, and After
Dark 3.0, were written specifically for the Windows environment.
In the Windows environment, these programs prevent any keystrokes
from interfering with their proper execution. However, in the
OS/2 environment, it is possible to switch context away from the
Windows session without notifying these programs. General
Protection Faults (GPFs) may result. Therefore, context
switching during the execution of WINBENCH95 and WINBENCH96 tests
is not recommended. Also, context switching during the execution
of the After Dark 3.0 demo is not recommended.

5. Problem with IBM AntiVirus 2.2 have been reported. This problem
can result in a system hang condition and is still under
investigation. The driver has been tested with thelatest version
(version 2.4) and no problems have been found. If you experience
problems with earlier versions, update to version 2.4.

6. When attempting to start a Win-OS/2 session from a DOS Full screen
command line, by typing 'WIN' as the executable - you must first be
sure that the settings of your DOS Full session are changed in the
following manner: Right Click on the DOS Full Screen icon and
choose "Settings", then select the tab - "Sessions". Select the
button titles DOS settings, and ensure that "All DOS Settings" is
selected from the list, then select OK. From the list of settings
which appear ensure that "VIDEO_8514A_XGA_IOTRAP" is switched OFF,
AND "VIDEO_SWITCH_NOTIFICATION" is switched to ON.
