Make sure the GD754X OS/2 Driver disk is labeled "CL DISP" by using DOS Label command (C:\DOS\LABEL A: or B:). 2. Install OS/2 v3.0 WARP! (if not already installed) and select "VGA" as the primary display adapter during installation. Do not select "Cirrus Logic" because it currently only supports Cirrus Logic desktop products. 3. Insert the Cirrus Logic GD754X OS/2 v3.0 Driver disk into the floppy drive. 4. Open an OS/2 Full-Screen session. 5. Change the prompt to the floppy drive which contains the driver disk. 6. Invoke the OS/2 batch file CLINST30.CMD using OS/2 boot drive, without a colon, as the parameter ([A:\]CLINST30 C). 7. Select the primary display type with the "Cirrus Logic GD754X" title. 8. Follow the applicable directions to ensure a complete installation. How to Change Screen Refresh Rates in OS/2 Desktop -------------------------------------------------- 1. During the driver installation process the Monitor Configuration/ Selection Utility dialog box will appear and display the following choices: (1) Default Monitor Type - this choice will use the monitor default settings. (2) Display Adapter Utility Program - with the aid of an application program such as CLMODE.EXE, this choice allows the user to set various screen refresh rates on all resolutions supported by their monitor. A dialog box will appear asking for the location and name of the utility program. For example: c:\vgautils\clmode.exe t640=75 t800=70 t1024=72 t1280=87 CLMODE.EXE comes with the DOS Drivers Disk The new settings will be saved to the BIOS and OS/2 will invoke SVGA.EXE to create a new SVGADATA.PMI file. The .PMI file will contain the screen refresh rates chosen from the utility program. How to Change Resolution & Colors in OS/2 Desktop ------------------------------------------------- 1. After driver installation is complete, open the System Setup folder. 2. Locate the System icon, mark it then hit the return key or double-click the icon to execute the program. 3. The first screen has 2 pages. The first page displays all the available resolutions, number of colors and screen refresh rate. 4. The second page has two sections: Display Name, which displays various monitor types, and View Current Configuration, which displays the maximum resolutions and screen refresh rates for the type of monitor selected. 5. After the selections are made, close the System applet and execute a Shutdown to allow the changes to take effect. NOTE: Choosing different screen refresh rates in the System applet will have NO effect to the current configuration. How to Change Resolution & Colors in WIN-OS/2 Full-Screen Session ----------------------------------------------------------------- 1. The WIN-OS/2 full-screen or windowed session will be configured with the same resolution and number of colors chosen for the OS/2 PM desktop. For example, if 800x600x65536 colors is chosen in an OS/2 desktop, opening a WIN-OS/2 session will also display 800x600x65536 colors. NOTE: Do NOT execute Winmode to change resolution and colordepth in a WIN-OS/2 session.
