After display driver-related files have been copied to the user's system it is necessary to update different system configuration files to complete the installation process. Frequently, the CONFIG.SYS and OS2.INI files need to be updated to complete PM display driver installation and the SYSTEM.INI and WIN.INI files need to be updated to complete the WIN-OS/2 display driver installation. Depending on the display driver to be installed, other configuration files might also have to be updated.
