### 16-Bit SVGA Base Video Handler

Driver Description:

Base video handlers are used to access video devices and provide display support for full-screen sessions. The 16-Bit SVGA Base Video Handler provides support for SVGA displays. This module provides support for a superset of the VGA base video handler and, therefore, relies on the VGA base video handler to be loaded in order to work.

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

4.Invoke NMAKE on the resident makefile.

Files Created By Successful Build:

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