It seems that you want to use ndiswrapper is that correct?
If so you'll need the windooze driver files. and the ndiswrapper tar.gz files.
And in order to install them correctly you'll have the Development tools and the kernel sources installed as I posted already.
so 1st get the kernel sources (everything as root) on a console
e.g. change to /tmp then
rpm -ivh kernel-2.6.17-1.2174_FC5.src.rpm
download the ndiswrapper from this
tar zxvf ndiswrapper-1.23.tar.gz
Everything is prepared so far...
Now I hope that you know how to extract the winxp driver files of your wireless card. Copy them to for e.g. /tmp/wlan
Do this as next step
ndiswrapper -i /tmp/wlan/THE NAME OF THE INF FILE e.g. btw10.inf
with this command you can check if everthing worked well so far
-l = list inserted drivers
then you will have to edit the modprobe.conf with this command
now you're able to configure your card
