Right click on the device in device manager, select details
and display "hardware ids".

You will see something like PCI\VEN_xxxx&DEV_yyyy and so on.

STFW is short for "Search The Fine Web". VEN is vendor id, Dev is device
id, both are 4 digit numbers, I believe in hex, but it does not mater
for searching. 

The vendor id and device id is constant, so you can also search to see
if there is a Linux or xBSD driver for it too.

Not all manufacturers use the same device number, sometimes for different
versions of the same card/device. For example, I have a Realtek 8139 card
made by a company that used 8139 as the device id, like everyone else does,
but for the heck of it produced a few with a different id and no one including
themselves had drivers for it. I assume it was for a specific box vendor,
I was unable to find.
