I got a new PCI wireless adapter.  I went over to the manufacturer web
site to download the latest drivers, but it requires you to install
the manufacturer wireless utility, which I don't want.  I just want to
use Windows' built-in wireless utility.  So I went into the Device
Manager and told Windows to update the driver for the wireless
adapter, and it found it on the Internet somewhere.

I want to make a backup of that latest driver, in case I ever need to
re-install it and the internet is down or the driver is no longer
available from whichever site Windows found it on.  So which files do
I need?  Just the .SYS file?  Or do I also need .CAT and .INF files?
