INSTALLATION GUIDE FOR OS/2 2.1X 256 COLOR ACCELERATION DRIVERS

                          FOR SpeedStar Pro SE

--------------------------------------------------------------------------



Programs you need for Installation.

-----------------------------------

SSMODE.EXE -- SpeedStar Pro SE monitor setup utility.



IMPORTANT NOTE:

-----------------

IBM's DSPINSTL.EXE calls SVGA.EXE to identify the SVGA chipset before

proceeding with the installation of a display driver. The IBM SVGA.EXE

shipped with OS/2 2.1 does not correctly ID the Cirrus Logic Chipset.

Running CLINST21.CMD will update SVGA.EXE with the new Cirrus SVGA.EXE

before calling DSPINSTL.EXE.  This will help OS/2 identify the Cirrus

Logic Chipset correctly.



If you are having trouble installing the Cirrus Logic Drivers, manually 

rename the IBM SVGA.EXE TO SVGA.IBM and copy the new SVGA.EXE file 

to your OS/2 subdirectory. Information about SVGA.EXE can be found in

the OS/2 Users Manual on Page 339.  



During installation, the target file may have a newer date than the

source file, select the 'Yes' button when the installation program display

a dialog box to notify the user of this situation.
