Please use the diskcopy utility if a backup diskette is made. NOTE: This procedure assumes you are installing from A: to C: If this is not the case make appropriate adjustments. 1. Boot the OS/2 SYSTEM. 2. Open an OS/2 WINDOW or OS/2 FULL SCREEN command session. 3. Insert the Cirrus Logic Installation diskette in drive A. 4. From the OS/2 session type "A:setup A: C:" [enter]. 5. From the DISPLAY DRIVER INSTALL window, select PRIMARY DISPLAY select OK. 6. From the PRIMARY DISPLAY DRIVER LIST window, select CLGD546X select OK. 7. From the SOURCE DIRECTORY window, make sure source directory points to location of installation diskette (use Change radio button to select the proper drive, if necessary) select INSTALL 8. Shutdown, and Restart your system when prompted. (remove the diskette from A: before restarting). 9. The display driver will come up in 640x480 mode. You may change the display resolution by following the instructions in "OS/2 3.0 (Warp) and 4.0 (Merlin) Resolution Modification". 2.1 OS/2 3.0 (Warp) and 4.0 (Merlin) Resolution Modification To change resolutions and pixel depths within the driver AFTER INSTALLATION, take the following steps: 1. Click your right mouse button on the OS/2 Desktop and select the entry "System Setup". When the folder opens, double click on the SYSTEM icon. 2. Select the Screen Resolution from among those listed, then close the System Settings Window by double clicking on the top-left corner. (NOTE: you must shut-down using the Shut down radio button on the Launch pad, and re-boot before the change will actually take place) If the display is blank, or illegible after changing the resolution, it is likely due to the monitor not being capable of that resolution setting. To fix this, reboot OS2, and when you see the white rectangular box and "OS2" in the upper left corner of the screen, press ALT-F1. This will allow you to boot in VGA mode, and change the display resolution to a setting supported by your monitor. 2.2 OS/2 3.0 (Warp) and 4.0 (Merlin) Display Selection DDC SUPPORT: When the VESA Display Data Channel (DDC) protocols are supported in the video BIOS, the operating system, and the monitor, the monitor capabilities can be automatically reported to the system. When DDC monitor is selected, the system will read the video capabilities from the monitor and only allow those modes which are supported by the monitor and the video subsystem. The video information includes resolution, color depth, and refresh rate. MONITOR SELECTION: To select a particular monitor, or to enable DDC monitor: 1. Click your right mouse button on the OS/2 Desktop and select the entry "System Setup". When the folder opens, double click on the SYSTEM icon. 2. Select the Screen tab, and go to page 2 to select the display. Note: changes will not take effect until the system is rebooted. 2.3 MONITOR.DIF file The OS2 directory (C:\OS2\) in your PC contains a file (MONITOR.DIF) which lists many monitors, and their video capabilities. This file may be edited to include other monitors which the user may have. At the end of this file (README.TXT) you will find updated information which may be used to correct MONITOR.DIF for some IBM monitors, and for the P201 in particular. For OS2 V4, it is best to select DDC as the monitor selection. For earlier versions of OS2, one must select a monitor which most closely matches the video capabilities of the monitor being used, or edit MONITOR.DIF file to include video characteristics of the monitor being used. Please see your OS2 documentation for details. 3.0 Trademarks _______________ The following terms are trademarks of the IBM Corporation in the United States and/or other countries: IBM OS/2 OS/2 Warp The following terms are trademarks of other companies: Cirrus Logic Cirrus Logic, Inc.
