I bought a Microsoft MN-520 WLAN card (Prism 2 chipset). It works well under Linux, but I want to use it with FreeBSD.
The card does not currently exist in the pccarddevs database, so the if_wi
drive doesn't recognize it. I've added it with this patch:

Then, I regenerated the .h files with "make -f Makefile.pccarddevs".
Finally, I added the card's data to the if_wi driver:

and then recompiled the kernel. Unfortunately, the driver still doesn't
seem to attach to the card (when I "kldload if_wi.ko" from sysinstall's
holographic shell, with a floppy with the "corrected" driver).
What else can I do? Is there anything else I should edit?
