INSTALLATION 103. LICENSE 11 12 131. 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.) 73 743.
