Configuring Wireless 2100 Driver for Linux

# aptitude install ipw2100-modules-[kernel version]

* LOADING FIRMWARE VIA HOT-PLUG

Before you can load the driver, you need the firmware image.  You can find
instructions for obtaining the firmware by going to:

http://ipw2100.sf.net/firmware.php.

Once you have the firmware, unzip the archive.  You should find seven (4)
files within it:

    LICENSE    A copy of the firmware license
ipw2100-(version number).fw  Boot strap image
ipw2100-(version number)-i.fw  Used in IBSS mode
ipw2100-(version number)-p.fw  Used in monitor mode

You need to place all of these files into the hotplug firmware directory,
e.g. /usr/lib/hotplug/firmware/  or  /lib/firmware/.  Check the contents
of the /etc/hotplug/firmware.agent to determine the specific location for your
distribution.
