- 1. OVERVIEW
- The file iwlwifi-3945.ucode provided in this package is required to be
- present on your system in order for the Intel PRO/Wireless 3945ABG/BG Network
- Connection Adapter driver for Linux (iwlwifi-3945) to be able to operate
- on your system.
- 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-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.
- 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-3945.ucode /lib/firmware
- You can now load the driver (see the INSTALL and
- README.iwlwifi-3945 provided with the iwlwifi-3945 package for
- information on building and using that driver.)
