[st.john]

Hi Guys,
i am looking for info that will enable me to use my internal pci cisco 
wireless card on my ibm t40 laptop under freebsd 5.4 How do I set this 
up ? I have googled and searched freebsd.org but have been unable to 
find info that will describe what is involved and how to set up the 
config files, drivers etc. Any help would be greatly appreciated,

many thanks,

St.john
