You must have OS/2 DOS Support installed in order to install this driver. 2. If you previously installed SVGA, or any Cirrus Logic Driver, you must return to VGA mode before installing any subsequent driver. Please use the procedures in the following section. 4.0 SETTING YOUR MONITOR TO VGA MODE ____________________________________ Use the following procedures to return to VGA mode. o If you are installing this device driver on OS/2 Warp and you do not have a usable OS/2 Desktop, use the following procedures to return to VGA mode. However, if you have a usable Desktop, it is recommended that you use Selective Install to set your monitor to VGA mode. 1. Turn on your computer. If your computer is already on, press Ctrl+Alt+Del to restart it. 2. When a small white box appears in the upper-left corner of your screen, press Alt+F1. If you see the OS/2 Logo displayed, you must start again at step 1. 3. When the Recovery Choices screen appears, press V. Your video adapter is now restored and can work in VGA mode. If you want to install a new video adapter or video device driver, refer to Chapter 16, "Video Procedures," in the User's Guide to OS/2 Warp. 5.0 INSTALLATION OF DISPLAY DRIVER FROM DISKETTE ________________________________________________ To install the Cirrus Logic Device driver from diskette, do the following: 1. Insert the Cirrus Logic diskette into drive A: 2. Double click "OS/2 System" Folder. 3. Double click on the Drives icon. 4. Double click on Drive A: 5. Double click on Install.exe. 6. Choose "Install" from the Cirrus Logic Install Program. 7. Click OK to let Install identify your graphics hardware and memory configuration. 8. Select "Yes" to change your display driver settings. 9. Select a screen resolution and close System Settings dialog box. 10. Close down Drive A - Icon View, Drives - Icon View and System Setup Icon View. 11. Remove the diskette from Drive A: 12. Shut down and reboot the system. Note: If video memory size is changed in a system, the user must re-install Cirrus drivers (by re-installing VGA drivers first, then the Cirrus drivers). Refer to Section 3.0 above. 6.0 RUNNING IN UNATTENDED MODE ______________________________ Install as follows: At the command prompt, type: A:] install /r:install.rsp where == floppy or hard drive containing installation media The INSTALL.RSP file contains a list of default responses to installation options. These options are the location of drive containing the media, or use of an optional log file (for logging the unattended installation). 7.0 LIMITATIONS _______________ o The Refresh Rate Change on the Fly Utility does not detect DDC monitors 8.0 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: TRADEMARK OWNER Cirrus Logic Cirrus Logic, Inc.
