### Creating a Display-Driver Installation Package

A complete display-driver installation package usually will include the following types of files:

DSPINSTL utility program

DLL, including the action routines (if action routines are used)

One or more DSC configuration files (containing DSC entries for each driver package)

Display driver files (PM or WIN-OS/2)

Other files to be copied (if necessary)

One or more DSP files (containing DSPINSTL installation and configuration commands)

Programs to be triggered by the :RUN commands in DSP files (as needed)

A display-driver package can span multiple diskettes. If so, each diskette must include the DSP files that explain what to do with the files on the diskette. The display driver files (and related files) can be packed (by the PACK.EXE utility program).

If the files are packed, their last file-name character must be set to the "@" character. DSC files, DSP files, the action-routine DLL, and the DSPINSTL utility program must not be packed.
