131. OVERVIEW
14
15The file iwlwifi-3945.ucode provided in this package is required to be
16present on your system in order for the Intel PRO/Wireless 3945ABG/BG Network
17Connection Adapter driver for Linux (iwlwifi-3945) to be able to operate
18on your system.
19
20On adapter initialization, and at varying times during the uptime of
21the adapter, the microcode is loaded into the RAM on the network
22adapter. The microcode provides the low level MAC features including
23radio control and high precision timing events (backoff, transmit,
24etc.) while also providing varying levels of packet filtering which can
25be used to keep the host from having to handle packets that are not of
26interest given the current operating mode of the device.
27
282. INSTALLATION
29
30The iwlwifi-3945 driver will look for the file iwlwifi-3945.ucode using the
31kernel's firmware_loader infrastructure. In order to function
32correctly, you need to have this support enabled in your kernel. When
33you configure the kernel, you can find this option in the following
34location:
35
36 Device Drivers ->
37 Generic Driver Options ->
38 Hotplug firmware loading support
39
40
41You can determine if your kernel currently has firmware loader support
42by looking for the CONFIG_FW_LOADER definition on your kernel's
43.config.
44
45In addition to having the firmware_loader support in your kernel, you
46must also have a working hotplug and udev infrastructure configured.
47The steps for installing and configuring hotplug and udev are very
48distribution specific.
49
50Once you have the firmware loader in place (or if you aren't sure and
51you just want to try things to see if it works), you need to install
52the microcode file into the appropriate location.
53
54Where that appropriate location is depends (again) on your system
55distribution. You can typically find this location by looking in the
56hotplug configuration file for your distro:
57
58 % grep \"^FIRMWARE_DIR\" /etc/hotplug/firmware.agent
59
60This should give you output like:
61
62 FIRMWARE_DIR=/lib/firmware
63
64If it lists more than one directory, you only need to put the
65microcode in one of them. In the above example, installation is
66simply:
67
68 % cp iwlwifi-3945.ucode /lib/firmware
69
70You can now load the driver (see the INSTALL and
71README.iwlwifi-3945 provided with the iwlwifi-3945 package for
72information on building and using that driver.)
