### 16-Bit PM (VGA) Display Driver

Driver Description:

The 16-Bit PM (VGA) Display Driver manages the display device for the Presentation Manager interface. This driver contains a set of I/O routines that provides hardware-independence to Presentation Manager applications.

Compilers/Assemblers Required:

         Microsoft MASM 5.1  (supplied with the DDK)

Build Instructions:

1.Set the environment variables so the correct tools are picked up during the build.

    e.g., SET PATH=<drive>:\DDK\TOOLS;%PATH%

Where <drive> represents your DDK installed drive and DDK represents the DDK installed directory. On the CD-ROM, the TOOLS directory path is DDK\ TOOLS.

2.Change the directory to DDK\VIDEO\SRC\PMDISP\EGAFAM\EGAVGA.

3.Invoke NMAKE VGARET on the resident makefile.

This builds the Retail version of the driver.

4.Invoke NMAKE VGADEB on the resident makefile.

This builds the Debug version of the driver.
