DOS extender

Alexandre-Xavier Labonté-Lamoureux edited this page Apr 25, 2017 · 2 revisions

A 32-bit DOS extender is required to run the executable. It needs to be added to the executable's directory.

The original Doom used DOS/4G as the DOS extender and it was embedded into the executable. Open Watcom C doesn't support to embed the DOS extender, so it must be provided as a separated file from the executable.

Once compiled and executed, the program will look for the file dos4gw.exe. It is suggested that you use the DOS/32 Advanced DOS Extender instead. You can download dos32a.exe here. Once downloaded, rename it to dos4gw.exe a put it into the executable's directory.
