### DSPINSTL Installation Script Example

The installation of display drivers on OS/2 is done, in most cases, using IBM's display configuration tool DSPINSTL.EXE. When installing SVGA support , DSPINSTL.EXE calls a DOS program, SVGA.EXE, to create an SVGADATA.PMI file. The .PMI file is a data file containing all the information about the SVGA display adapter installed. DSPINSTL.EXE also uses SCREEN01.SYS for its detection; SVGA.EXE has some limited dependencies on SCREEN01.SYS as well. Because of these dependencies, installing BBS drivers is a two part process , as discussed below.
