pesky 1450

[jfhawk06]

hi, i'm definitely new to linux but trying my hardest to get it up and working and i realize there are a ton of posts outlining the installation of the dell wireless WLAN1450 broadcom wireless chip. but, i'm having trouble i havent yet seen addressed. i've located the two files i need (bcmwl5a.inf and bcmwl5.sys)...when i boot knoppix 3.7, i use the boot command "knoppix26". i go to ndiswrapper and select the .inf file, but it gives me either the message "perhaps knoppix isnt compatible with your driver" or "this is not a .inf file..." or something along those lines. any ideas?
thank you in advance
Joe
