Mac OS 7.5.3 or Later Extension Folder
In a Macintosh there are two files in the "Extensions"folder that are required to add
functionality to the Viking fax/modem card. They are the "PC Card Extensions"and
the "PC Card Modem Extensions." The "Extensions" folder is located in the "System
Folder" on the hard drive. As you insert the Viking fax/modem into the PC Card

ware settings menu, a choice for "PC slot" will be available under the "Connection"
option. If these files are not found on your computer, contact your dealer.
