### SVGA Utility

Driver Description:

The SVGA Utility consists of an executable file called SVGA.EXE, which is used to generate information about the chip set on the SVGA adapter, such as the video modes supported by the adapter and values in the video registers when the adapter is in each video mode.

Compilers/Assemblers Required:

         Microsoft MASM 5.1  (supplied with the DDK)
         Microsoft C 6.0

Build Instructions:

1.Ensure the necessary compilers and assemblers are installed.

2.Run the SETCMPLR.CMD REXX command file located in the DDK\TOOLS directory. This command initializes environment variables to be used during the build.

e.g., SETCMPLR <MSCpath> <VACpath> <CSETpath> <DDKpath>

    Where <MSCpath> represents the Microsoft C 6.0 install directory
           <VACpath> represents the IBM Visual Age C++ install directory
           <CSETpath> represents the IBM C Set ++ install directory
           <DDKpath> represents the DDK install directory

Note: A period (.) may be substituted for a compiler directory that is not used during the build.

3.Change the directory to DDK\VIDEO\SRC\VIDEO\SVDH\SVGAUTIL.

4.Invoke NMAKE on the resident makefile.

Files Created by Successful Build:

         Directory:  \DDK\VIDEO\REL\OS2C\RETAIL\BASE\OS2
