- How to Install OS/2 Desktop Driver & WIN-OS/2 Full-Screen Session
- -----------------------------------------------------------------
-
- 1. 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.
-
-
- Known Problems
- --------------
-
- 1. The title bar will disappear or will move to the bottom of the screen
- when switching back from a PM desktop to an OS/2 full screen session.
- Problem is evident only in SimulSCAN display using a resolution of
- 640x480 at 64K colors with an 800x600 SVGA TFT panel.
-
- 2. Launch OS/2 in SimulSCAN display. Open a DOS window then press Alt-Home
- to open a full-screen DOS. The display in the Panel side will disappear.
- Problem occurs with the following resolutions and colordepths:
- 640x480 256 & 64k colors
- 800x600 256 & 64k colors
- 1024x768 256 colors
-
- 3. Launch OS/2 in SimulSCAN display, open a full-screen OS/2 session then
- press Alt-Esc to go back to the PM desktop. Open a full-screen DOS,
- switch display to CRT, then close the DOS session. Press Alt-Esc until
- the OS/2 full-screen display appears. This process will cause the panel
- display to shake up and down. Problem occurs only with an 800x600 SVGA
- TFT Panel when using the following resoltuions and colordepths:
- 640x480 256 & 64k colors
