      INSTALLATION GUIDE FOR OS/2 2.1 256 COLORS BLITTER DRIVER
                   FOR CIRRUS LOGIC'S GD542X CHIPS
--------------------------------------------------------------------------

Programs you need for Installation.
-----------------------------------
Clmode.exe or Video Adapter Utility program to select monitor type.

IMPORTANT NOTE:
-----------------
IBM's DISPINST.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.
