The only driver files I could find for this modem created install diskettes. I did not have a disk drive on my Omnibook 900 so I created a diskette on my wife's desktop then copied the folder to the laptop hard drive, located the folder I copied the files to and executed setup.exe. I used Power Archiver to create a zip file of this folder for all you folks that do not have or cannot use a floppy. Check readme.txt for special instructions on certain Omnibooks and Toshiba models. Unzip to hard drive, should create folder 3CXM556.
