OEM adapter device drivers that are packaged in the OS/2 product are installed near the end of the OS/2 system installation. At this point in the installation process, the DDP files for each OEM adapter device driver are evaluated by the DDINSTAL interpreter. This processing is completely automatic and transparent to the end user.

Use the same DDINSTAL framework for adapter device drivers that you distribute directly. Include the driver file, presence-check function, and DDP file on a reference diskette for the OEM adapter. The end user can install the adapter device support from the reference diskette, after the OS/2 operating system is loaded, by selecting Device Driver Install from the OS/2 System Setup folder. The installation of the device support will proceed automatically.
