2. INSTALLATION

The iwlwifi-3945 driver will look for the file iwlwifi-3945.ucode using the
kernel's firmware_loader infrastructure.  In order to function
correctly, you need to have this support enabled in your kernel.  When
you configure the kernel, you can find this option in the following
location:

        Device Drivers ->
                Generic Driver Options ->
                        Hotplug firmware loading support


You can determine if your kernel currently has firmware loader support
by looking for the CONFIG_FW_LOADER definition on your kernel's
.config.

In addition to having the firmware_loader support in your kernel, you
must also have a working hotplug and udev infrastructure configured.
The steps for installing and configuring hotplug and udev are very
distribution specific.
