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.

4.0 Preliminary Steps

______________________

The following steps must be performed before you install the

Trio3D graphics-accelerator device driver:

1. You must have OS/2 DOS Support installed.

2. If you previously installed SVGA support, you must reset the

resolution to VGA mode, using the procedures in "Setting Your

Display to VGA Mode" (section 5.0 in this README).

3. The device driver diskette must be labeled "S3 DRV1."

4. After driver installation, the OS/2 SYSLEVEL command may be used to

confirm the new driver version level. It may also be used prior to

installation to verify the current driver version, however, some

previous device drivers did not provide this information. Following

execution of the SYSLEVEL command look for the following information:

C:\OS2\INSTALLATION\SYSLEVEL.VID

Trio3D

Version 2.81 Component ID 562107701

Current CSD level: S328103

Prior CSD level: S328018

In this case the current version level is S3 2.81.03.

5. In some situations, installing this driver over 2.80.xx and 2.81.xx

versions of the driver can result in duplicated icons. To prevent

this problem, you should delete the "S3 Windows Font Size" and

"DDC Display Setup" icons from the System Setup Folder prior to

installing this driver.

5.0 Setting Your Display to VGA Mode

_____________________________________

Use the following procedures to reset to VGA mode.

NOTE: If your display is out of sync, start OS/2 using the OS/2

Installation Diskette. Insert Diskette 1 when prompted, press

F3 to display a command prompt, and then use the following

instructions to reset your display mode.

o If you are installing this driver on OS/2 2.11 or OS/2 for

Windows, and you installed from diskettes, do the following:

1. Under OS/2 2.1/2.11, before running RSPDSPI, delete the following

file:

[OS2 DRIVE]:\OS2\INSTALL\00S3.DSC

3. Be sure RSPDSPI.EXE is in the \OS2\INSTALL directory. If it

is, go to step 3. If it is not, insert Diskette 8 into

drive A and unpack RSPDSPI.EXE with the following command:

C:\OS2\UNPACK A:\INSTAID C: /N:RSPDSPI.EXE

where A: is the drive containing Diskette 8, and C: is the

drive where OS/2 is installed.

4. Type C: and then press Enter.

5. Type CD C:\OS2\INSTALL and then press Enter.

6. Type the following:

RSPDSPI /PK:VGA /SK:NONE /S:A:\ /T:C:

In /T:C:, C: is the target drive where OS/2 is installed. In /S:A:,

A: is the source diskette drive for installing the device driver.

Then press Enter.

7. Perform a shutdown and restart your computer.

o If you are installing this driver on OS/2 2.11 or OS/2 for

Windows, and you installed from CD-ROM or a LAN, do the

following:

1. Under OS/2 2.1/2.11, before running RSPDSPI, delete the following file:

[OS2 DRIVE]:\OS2\INSTALL\00S3.DSC

3. Be sure RSPDSPI.EXE is in the \OS2\INSTALL directory. If it

is, go to step 3. If it is not, unpack RSPDSPI.EXE with the

following command:

C:\OS2\UNPACK E:\DISK_8\INSTAID C: /N:RSPDSPI.EXE

where C: is the drive where OS/2 is installed, and E: is

the CD-ROM or LAN drive.

4. Type C: and then press Enter.

5. Type CD C:\OS2\INSTALL and then press Enter.

6. Type the following:

RSPDSPI /PK:VGA /SK:NONE /S:E:\OS2SE21\ /T:C:

In /T:C:, C: is the target drive where OS/2 is installed. In /S:E:,

E: is the source CD-ROM or LAN drive.

Then press Enter.

7. Perform a shutdown and restart your computer.

6.0 Installing from Diskette

_______________________________

To install the Trio3D device driver from diskette, do the

following:

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

2. Insert the Trio3D 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

where A: is the diskette drive.

Then press Enter.

Setup will then identify your chipset. When prompted to do so, press

Enter to continue.

Due to the limitations with a single pass installation. A dialog box

may come up during installation with the message, "The installed adapter

does not support the selected display driver. Do you wish to continue?".

Please continue the installation by selecting the Yes button.

5. 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

refresh rate. Then select OK.

If you select the "Install Using Display Adapter Utility

Program" choice, you must have the DOS monitor utility program

that came with your display adapter. Contact the display

adapter manufacturer's technical support for information on how

to use the monitor utility program under OS/2.

NOTE: DSPINSTL determines the hardware configuration by

creating the \OS2\SVGADATA.PMI file. If the

\OS2\SVGADATA.PMI file has not been created, the adapter

will not be supported. This process can take several

seconds and will black-out the screen.

6. When the Source Directory pop-up window appears, insert S3

Trio3D diskette into drive A. Then select Install.

7. When prompted to do so, select OK to perform a shutdown, and then

restart your computer. Make sure the diskette has been removed from

the install drive.

8. When the system has restarted:

a. Open the OS/2 System folder.

b. Open the System Setup folder.

c. Open the System object.

d. When the Settings notebook appears, select the Screen tab.

If your monitor has been detected as Plug and-Play (DDC)

compatible, go to step 10.

9. On Screen page 2, select your display from the display list. If

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.

10. When the system has restarted:

a. Open the System object and select Screen page 1, as in step

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.

o When starting a WIN-OS/2 session it is recommended that the user launch

the session via one of the WIN-OS/2 icons located in the "Command

Prompts" folder within the "OS/2 System" icon. For additional information

see section 10.0 Limitations.

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 Trio3D device driver

diskette.

o OS/2 must have been successfully installed on the client using

the CID (Configuration Installation Distribution) method.

To install the Trio3D 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.

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 CONFIGSYSLINE

keyword of the CID response file:

SET RESTARTOBJECTS=STARTUPFOLDERSONLY

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. DISPINSTL 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 2.81.05, 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. In all modes, video corruption or out-of-sync screen is

displayed when using Alt+Esc to switch between WIN-OS/2,

OS/2, and DOS window and full-screen sessions started from the

Startup folder. To avoid this situation, do not start sessions

from the Startup folder or press Alt+Esc several times to

restore.

5. 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.

6. When attempting to start a WIN-OS/2 session from an OS/2 Full Screen

session by typing "WIN" or "WINOS2" at the command prompt, it will not

execute with the settings needed to support WIN-OS/2, and will result

in video corruption and/or a system lockup. It is recommended that the

user launch all Windows sessions via one of the WIN-OS/2 icons located

in the "Command Prompts" folder within the "OS/2 System" icon.

7. When attempting to start a WIN-OS/2 session from a DOS Full screen or

DOS Window by typing the "WIN" or WINOS2" command, the user must first

be sure that the video settings of the session are changed to enable

this feature. These settings can be changed using the following

procedure:

a) Place mouse pointer over the DOS Full Screen icon (or any DOS

session icon you want to alter). Press mouse button 2 (MB2), the

right button, to bring up a context sensitive menu.

b) Place mouse pointer over "Setting" and press MB1. Next, place

mouse pointer over the tab labeled "Session" and press MB1 again.

c) Use MB1 to chose the "DOS Setting" button.

d) Use MB1 to chose the "DOS video settings" option, and then click OK.

e) From the list of settings which appear ensure that

"VIDEO_8514A_XGA_IOTRAP" is switched OFF, AND

"VIDEO_SWITCH_NOTIFICATION" is switched to ON,

then "save" these settings using MB1.
