I've forgotten what program should execute to install an .inf file. I am trying to upgrade my US Robotics sportster 56K INT Voice modem to use V.90. I installed the modem upgrade file for the internal voice modem. But there are two additional files that I am supposed to also install ( 3comwave.inf and 5605wave.inf.) When I use the Add/Remove Programs Install feature and point to either of the .inf files on the floppy, Notepad opens them up for viewing.
