umm, whatever you downloaded for windows (the drivers, im guessing), wont help on linux.
why dont you just pop the card in when your running mdk, and pray it picks it up? if you'r e lucky, the kernel that is on it would recognize it.
you'll know if it does when it gives you two high-pitched beeps. one high-pitched followed by another low-pitched means you will have to make some changes to the system.
also, to know if anything happened when you inserted your card while running mdk, open a terminal and type in "dmesg". look for something related to your card (itll be towards the end of the file anyways). after you see the card loaded from dmesg o/p, run the command "iwconfig" in the terminal, and see what interface it is on (wlan0/eth0/wlan1/eth1...)
umm, ill stop here now. write back if the cards recognized.
