Well i think you don't need the 2 others Cds anyway
wireless cards drivers aren't available by default perhaps for the sound one because for me it detects early at installation my Sound Blaster SBLive...
Bah now you just have to surf to the devices constructors web islands to see if they offers linux support
Find their sites
And if you find nothing there
I suggest you to go to http://www.sourceforge.com
where all linux projets including wireless drivers are maintained
Hope this helps bye
