Intel Wireless WiFi Link 4965AGN Adapter Copyright (C) 2006 - 2007 Intel Corporation. All rights reserved. Microcode Package README.iwlwifi-4965-ucode INDEX 1. OVERVIEW 2. INSTALLATION 3. LICENSE 1. OVERVIEW The file iwlwifi-4965-1.ucode provided in this package must be present on your system in order for the Intel Wireless WiFi Link 4965AGN driver for Linux (iwlwifi-4965) to operate on your system. The "-1" in the filename reflects an interface/architecture version number. It will change only when changes in new uCode releases make the new uCode incompatible with earlier drivers. On adapter initialization, and at varying times during the uptime of the adapter, the microcode is loaded into the RAM on the network adapter. The microcode provides the low level MAC features including radio control and high precision timing events (backoff, transmit, etc.) while also providing varying levels of packet filtering which can be used to keep the host from having to handle packets that are not of interest given the current operating mode of the device. 2. INSTALLATION The iwlwifi-4965 driver will look for the file iwlwifi-4965-1.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. Once you have the firmware loader in place (or if you aren't sure and you just want to try things to see if it works), you need to install the microcode file into the appropriate location. Where that appropriate location is depends (again) on your system distribution. You can typically find this location by looking in the hotplug configuration file for your distro: % grep \"^FIRMWARE_DIR\" /etc/hotplug/firmware.agent This should give you output like: FIRMWARE_DIR=/lib/firmware If it lists more than one directory, you only need to put the microcode in one of them. In the above example, installation is simply: % cp iwlwifi-4965-1.ucode /lib/firmware You can now load the driver (see the INSTALL and README.iwlwifi provided with the iwlwifi package for information on building and using that driver.) 3.
