iwlwifi-5000-5.ucode中的readme文件

我试着大概翻译了下：
1. OVERVIEW
/*这个包里提供的文件iwlwifi-5000-5.ucode，目的在于使英特尔无线网卡驱动（iwlagn）在linux系统下工作*/
The file iwlwifi-5000-5.ucode provided in this package must be
present on your system in order for the Intel Wireless WiFi Link
AGN driver for Linux (iwlagn) to operate on your system.


The "-5" 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 memory 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
/*iwlagn驱动将会用内核的firmware_loader infrastructure查找iwlwifi-5000-5.ucode文件。为了能够正常工作，在你的内核中必须有firmware_loader infrastructure支持。没有的话，当你配置内核时，可按如下步骤进行配置*/
The iwlagn driver will look for the file iwlwifi-5000-5.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

/*你可以通过查看内核中的.config文件来确定你当前内核是否有firmware loader支持*/
You can determine if your kernel currently has firmware loader support
by looking for the CONFIG_FW_LOADER definition on your kernel's
.config.
/*除了有firmware_loader支持之外，你还必须有hotplug and udev infrastructure支持。安装和配置hotplug and udev的步骤是非常具体的*/
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.
/*一旦在合适的位置你有了firmware loader，你必须把这个代码文件安装到那个位置*/
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.
/*这合适的位置取决于你的系统分布。通常情况下，你可以在hotplug配置文件中通过查找FIRMWARE_DIR字符串发现这个合适的位置 */
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:
/*把文件拷贝到适当位置的目录下*/
% cp iwlwifi-5000-5.ucode /lib/firmware
/*现在你可以加载这个驱动了*/
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.)
