It conforms to the OS/2 32-bit, flat memory model and is designed to function as a 32-bit Presentation Manager graphics-display device driver under the OS/2 32-bit graphics engine. This device driver supports setting the refresh rate using the System - Settings notebook (page 2 of the Screen tab) in the OS/2 System Setup folder, and monitor detection using Display Data Channel (DDC) protocols. 2.0 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 S3 video 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 monitor 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 computer and install the new monitor. 3. Restart your computer. 4. Double-click on the DDC DISPLAY SETUP icon in the OS/2 System folder. 5. When you are instructed to do so, shut down your computer and restart it. 3.0 Preliminary Steps ______________________ The following steps must be performed before you install the Trio3D graphics-accelerator video 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 procedure under "Setting Your Monitor to VGA Mode" (section 5.0 in this README). 4.0 Setting Your Monitor to VGA Mode _____________________________________ To switch to VGA mode: 1. Start OS/2 Warp. 2. When the small white (OS/2) box appears in the upper-left corner of the screen, press Alt+F1; when the list of choices appears, press F3 (or V for OS/2 3.0). 5.0 Installing the S3 Video Device Driver ___________________________________________ To install the Trio3D device driver, do the following: 1. If your system is not in VGA mode, use the steps under section 5.0 to switch to VGA mode. 2. If installing from diskette, insert the Trio3D diskette into drive A. 3. Open an OS/2 full-screen or OS/2 window session. 4. At the OS/2 command prompt, execute X:\PATH\SETUP, where X:\PATH is the full path to the diskette drive or sub-directory to copy all driver files to the OS/2 drive. 5. Setup will then identify your chip set. When prompted to do so, press Enter to continue. Setup will then copy files. 6. When the Monitor Configuration/Selection Utility window appears, the "Install Using Defaults for Monitor Type" choice is preselected. Accept this choice by clicking OK. 7. When prompted to do so, select OK to perform a shutdown. Remove any diskettes from the floppy drive before restarting your computer. 8. Open the OS/2 System folder. 9. Open the System Setup folder. 10. Open the Display Driver Install object or type DSPINSTL at an OS/2 command prompt. When the Display Driver Install window appears, select PRIMARY DISPLAY DRIVER and then select OK. NOTE: If a message appears stating that the "Installed adapter does not match the driver", select OK to continue. 11. When the Primary Display Driver List window appears, select "S3 Trio3D [32 Bit] Version ...." then select OK to install the video driver. 12. When the Monitor Configuration/Selection Utility window appears, the "Install Using Defaults for Monitor Type" choice is preselected. Accept this choice by clicking OK. 13. When the Source Directory pop-up window appears, CHANGE the path statement to point to the driver files (same as in step 4.) If installing from diskette, insert the install diskette into the drive. Then select INSTALL. 14. When the installation is complete, remove any diskettes, shut down your system, and restart your computer. 15. 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 17. 16. On Screen page 2, select your monitor from the list. If your monitor does not appear in the list, select DEFAULT. It might be necessary to restart your computer to have all refresh rate options available. 17. When the system has restarted: a. Open the System object and select Screen page 1, as in step 15. 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 device 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 device driver might result in serious system problems. o To start a WIN-OS/2 session, double-click on 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." 6.0 Installing the S3 Video Device Driver in a CID Environment _______________________________________________________________ Notes: 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. /*****************************************************/ /* LCU PRODUCT DATA SECTION */ /*****************************************************/ . . . x.s3video = 15 x.15.name='S3 Video' x.15.statevar = 'CAS_' || x.15.name x.15.instprog = 'x:\img\s3_drvs\SETUP.CMD', ' /u /s:x:\img\s3_drvs' x.15.rspdir = '' x.15.default = '' x.s3dspinstl = 16 x.16.name='S3 CID Dspinstl' x.16.statevar = 'CAS_' || x.16.name x.16.instprog = bootdrive || '\os2\install\DSPINSTL.EXE', ' /pd:' || bootdrive || '\os2\install\00S3.dsc', ' /s:x:\img\s3_drvs', ' /t:' || bootdrive, ' /res:640x480x256', ' /u' x.16.rspdir = '' x.16.default = '' /*---------------------------------------------------*/ /* NUMBER OF PROGRAMS SET UP IN THE */ /* PRODUCT DATA SECTION */ /*---------------------------------------------------*/ NUM_INSTALL_PROGS = 16 /*****************************************************/ /* INSTALLATION SECTION */ /*****************************************************/ . . . when OVERALL_STATE = 2 then do if RunInstall(x.s3video) == BAD_RC then exit Call RebootAndGotoState(3) end when OVERALL_STATE = 3 then do if RunInstall(x.s3dspinstl) == BAD_RC then exit Call CheckBoot end . . . /******************************************************/ /* ROUTINE SECTION */ /* The following information should already exist in */ /* the LCU command file. */ /******************************************************/ . . .

Notes: o Be sure you have the stated video memory required, as listed under section 2.0 "Supported Resolutions." A safe choice is 640x480x256. Any of the listed resolutions can be selected, but your monitor might be damaged if you select a resolution that your monitor does not support. o After the Trio3D 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 to section 6.0 "Installing the S3 Video Device Driver from Diskette," step 12. 7.0 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. A message will be displayed indicating that the new settings will take effect the next time you restart your Windows session. 4. Click on the OK button. 5. 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 monitor resolution, or you install a new video device driver. 8.0 Features and Fixes Included in This Device Driver ______________________________________________________ These are the features and fixes included in this device driver: o "System - Settings" notebook support for setting refresh rate o DDC monitor detection support o Windows "Large font" and "Small font" support in high resolutions o WIN-OS/2 based on latest S3 Windows 3.1 drivers o One-diskette package 9.0 Limitations _________________ These are some known limitations: 1. CID install pauses due to SVGA.EXE loading in the background. Workaround: In the CID installation 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 using CID. * Restart the client system. * The client system will be configured with the correct device driver, display type, resolution and refresh rate. 4. In all modes, video corruption or an 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, do not perform context switching during the execution of WINBENCH95 and WINBENCH96 tests. Also, do not perform context switching during the execution of the After Dark 3.0 demo. 6. If you attempt 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 or a system lockup. Therefore, whenever you want to launch a Windows session, use 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, you 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 the mouse pointer over the DOS Full Screen icon (or any DOS session icon you want to alter). Press mouse button 2 (the right button) to bring up a context-sensitive menu. b. Click on SETTING; then click on the SESSION tab. c. Click on the DOS SETTING button. d. Click on DOS VIDEO SETTINGS; then click on OK. e. From the list of settings that appear, ensure that "VIDEO_8514A_XGA_IOTRAP" is set to OFF, and "VIDEO_SWITCH_NOTIFICATION" is set to ON; then save these settings by clicking on SAVE. 8.0 At 32 bpp color depth, the device driver might need a large swap space on the hard disk, for example, 15 MB. 10.0 Trademarks ________________ The following terms are trademarks of the IBM Corporation in the United States or other countries or both: IBM Presentation Manager NetView WIN-OS/2 OS/2 The following terms are trademarks of other companies: After Dark Berkely Systems, Inc.
