How to Change Resolution & Colors in OS/2 Desktop ------------------------------------------------- Follow steps 3-9 above 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 WIN-OS/2 Full-Screen Session ----------------------------------------------------------------- If you are running OS/2 2.1: 1. Open Win-OS/2 Full-Screen session. 2. Select File from drop-down menu in Windows Program Manager. 3. Insert the GD7543 Windows Driver disk into A: or B: and run INSTALL.EXE. 4.

If you are running OS/2 2.1 for Windows: 1. If you have already installed the WinMode utility from the Windows driver disk v1.00, make sure you select "OS/2-Windows" option if not already set. You can change color/resolution just like you do it in pure Windows environment. 2. If you haven't installed the GD7543 Windows Drivers previously, follow the steps listed in "If you are running OS/2 2.1" section above.
