#fw_update finds missing firmware

Have you used the OpenBSD command fw_update?  fw_update finds the missing firmware on your system and installs it for you.  The command has been avliable since 5.0. Guess I should read the changelogs or hang out on irc more.

I just used it to download and install the firmware for my old pcmci broadcom b card (bwi) and a hawking wireless n usb adapter (rsu) on a new laptop I have. That was really the easiest firmware install for any network interfaces ever. 

Simply log in as root and use the following command:
#fw_update

Depending on the firmware you need, you may see something like this.
rsu-firmware-1.1p0: ok
or
bwi-firmware-1.4p2: ok

After you get the OK, add your hostname.xxx0 file and restart the network.
#sh /etc/netstart 

Enjoy OpenBSD!
