### Installing and Configuring Display Device Drivers

The OS/2 Display Driver Installation utility program (DSPINSTL.EXE) provides all the facilities to install and configure OS/2 display drivers. In addition, DSPINSTL installs and configures Presentation Manager (PM) display drivers. It also can install and configure WIN-OS/2 (both full- screen and windowed) display drivers and install base video service (VIO) drivers and DOS virtual device drivers (VDDs).

Display-driver installation and configuration is more complex than it is for standard device drivers. Typically, display-driver installation and configuration includes the following activities:

Selecting the OS/2 display-driver characteristics

The user can specify the type and resolution of the display driver to be installed.

Copying display driver-related files

The user can copy display driver-related files from source directories ( usually on diskettes) to target directories on the user's hard disk. (See Copying Display Driver-Related Files.)

Updating the system configuration files

The user can update some of the OS/2 and WIN-OS/2 configuration files to prepare a new display driver for subsequent execution when the user's system is restarted. (See Updating System Configuration Files.)

These activities are described in detail in the following overview of display-driver installation and configuration.
