This is the Win 3.x driver for the S3 Trio64v+ video subsystem integrated in some IBM PC 300 and 700 series desktops. Not an easily found driver. Worked perfectly in my IBM PC350!
Do the following in DOS: 1)Copy or move this .exe file to a temp folder in your harddrive. 2)Insert a new formatted empty floppy diskette in A: or B:. 3)Go to the temp folder where the .exe file is located and run it. 4)Follow directions; it will unpack the display files to diskette. 5)Use that diskette to install the drivers, preferably in the Windows Setup in DOS. If you use Setup in Windows ingore the last prompt regarding the Trio Flat Screen part; just go back to DOS and finish the video part in Setup to ensure the drivers are installed.
Complete instructions included in this file. Good Luck!
