    Alltel EVDO, SUSE 10 KPC650

    Just installed Suse 10 Enterprise Desktop. Running on AMD x64 with 1gb RAM.

    I work for alltel and familiar with the EVDO network, however I am completely lost in linux, I jsut switched over from WinXp.. Tired of the 5001 different problems with windows.

    I have a Kyocera KPC650 registered on the Alltel EVDO Network. I pulled a file which was labeled as the Linux driver for the KPC650 from our Knowledge Base, but I am at a loss of where to start and how to install the card or the drivers. I have collected a multitude in information on this subject, but still not sure where to start. Well, enough to do... here is the driver info I pulled from the knowlege base. Someone please tell me where to start as I am a linux *virgin...
