Note As far as I can tell, these drivers are different than the ones currently on your site (or which the Atlas link points to). They are from the original installation diskette.
Used "Add New Hardware" Icon in "Control Panel," selected "Modem" from list, used "Have Disk," loaded raw files from floppy. Use "setmodem.exe" from DOS mode to load DOS driver.
