## CauseWay DOS Extender Support

The SciTech SNAP Graphics SDK is designed to work with Open Watcom C++ and both the DOS4G/W and CauseWay DOS extenders. It is recommended that you use the latest versions, as included with Open Watcom 1.2 or later. Earlier versions may not support required features, such as Intel MTRR programming.

In order to compile and link your programs to use CauseWay, either set the USE_CAUSEWAY=1 environment variable, or pass this variable on the command line to the dmake program.
