In This Release
===============

This file describes the Linux* Base Driver for the Atheros(R) AR8121/AR8113 PCI-E
Ethernet Adapter, version 1.0.0.5 This driver supports the 2.4.x and 2.6.x kernels.

This driver is only supported as a loadable mole at this time. Atheros is not
supplying patches against the kernel source to allow for static linking of
the driver. For questions related to hardware requirements, refer to the
documentation supplied with your Atheros(R) adapter. All hardware
requirements listed apply to use with Linux.

Building and Installation
=========================

To build a binary RPM* package of this driver, run 'rpmbuild -tb
<filename.tar.gz>'. Replace <filename.tar.gz> with the specific filename of
the driver.

NOTE: For the build to work properly, the currently running kernel MUST match
the version and configuration of the installed kernel sources. If you
have just recompiled the kernel reboot the system now.

RPM functionality has only been tested in Red Hat distributions.

1. Move the base driver tar file to the directory of your choice. For example,
use /home/username/arl1e or /usr/local/src/arl1e.

2. Untar/unzip archive:

tar zxf arl1e-x.x.x.x.tar.gz

3. Change to the driver src directory:

cd arl1e-x.x.x.x/src/

4. Compile the driver mole:

make install

The binary will be installed as:

/lib/moles/<KERNEL VERSION>/kernel/drivers/net/arl1e.[k]o

The install locations listed above are the default locations. They might
not be correct for certain Linux distributions. For more information,
see the ldistrib.txt file included in the driver tar.

5. Install the mole:

insmod arl1e <parameter>=<value>

6. Assign an IP address to the interface by entering the following, where
x is the interface number:

ifconfig ethx <IP_address>

7. Verify that the interface works. Enter the following, where <IP_address>
is the IP address for another machine on the same subnet as the interface
that is being tested:

ping <IP_address>

Command Line Parameters
=======================

If the driver is built as a mole, the following optional parameters are
used by entering them on the command line with the modprobe or insmod command
using this syntax:

modprobe arl1e [<option>=<VAL1>,<VAL2>,...]

insmod arl1e [<option>=<VAL1>,<VAL2>,...]

For example, with two L001 PCIE adapters, entering:

insmod arl1e TxMemSize=80,128
loads the arl1e driver with 8KB TX memory for the first adapter and 10KB TX memory
for the second adapter.

The default value for each parameter is generally the recommended setting,
unless otherwise noted.

NOTES: A descriptor describes a data buffer and attributes related to the
data buffer. This information is accessed by the hardware.

media_type
Valid Range: 0-4
0 - auto-negotiate at all supported speeds
1 - only link at 1000Mbps Full Duplex
2 - only link at 100Mbps Full Duplex
3 - only link at 100Mbps Half Duplex
4 - only link at 10Mbps Full Duplex
5 - only link at 10Mbps Half Duplex
Default Value: 0
media_type forces the line speed/plex to the specified value in
megabits per second(Mbps). If this parameter is not specified or is set
to 0 and the link partner is set to auto-negotiate, the board will
auto-detect the correct speed.

int_mod_timer
Valid Range: 50-65000
Default Value: 100
This value represents the minmum interval between interrupts controller
generated.

RxMemBlock
Valid Range: 16-512
Default Value: 64
This value is the number of receice memory block allocated by the driver.
Increasing this value allows the driver to buffer more incoming packets.
Each memory block is 1536 bytes.

NOTE: Depending on the available system resources, the request for a
higher number of receive descriptors may be denied. In this case,
use a lower number.

TxMemSize
Valid Range: 4-64
Default Value: 8
This value is the number KB of transmit memory allocated by the driver.
Increasing this value allows the driver to queue more transmits.

NOTE: Depending on the available system resources, the request for a
higher number of transmit descriptors may be denied. In this case,
use a lower number.

FlashVendor
Valid Range: 0-2
Default Value: 0
This value standards on vendor of spi flash used by the adapter.
0 for Atmel, 1 for SST, 2 for ST

Additional Configurations
=========================

Configuring the Driver on Different Distributions
-------------------------------------------------

Configuring a network driver to load properly when the system is started is
distribution dependent. Typically, the configuration process involves adding
an alias line to /etc/moles.conf as well as editing other system startup
scripts and/or configuration files. Many popular Linux distributions ship
with tools to make these changes for you. To learn the proper way to
configure a network device for your system, refer to your distribution
documentation. If ring this process you are asked for the driver or mole
name, the name for the Linux Base Driver for the Atheros AR8121/AR8113 is arl1e

As an example, if you install the arl1e driver for two AR8121/AR8113 adapters
(eth0 and eth1) and set the speed and plex to 10full and 100half, add the
following to moles.conf:

alias eth0 arl1e
alias eth1 arl1e
options arl1e Speed=10,100 Duplex=2,1

Viewing Link Messages
---------------------

Link messages will not be displayed to the console if the distribution is
restricting system messages. In order to see network driver link messages
on your console, set dmesg to eight by entering the following:

dmesg -n 8

NOTE: This setting is not saved across reboots.

Known Issues
============

NOTE: For distribution-specific information, see the ldistrib.txt file
included in the driver tar.

Driver Compilation
------------------

When trying to compile the driver by running make install, the following
error may occur:

"Linux kernel source not configured - missing version.h"

To solve this issue, create the version.h file by going to the Linux source
tree and entering:

make include/linux/version.h.

kernel with a supported adapter, email the specific information related to
the issue to [email protected]

B. linux下无线网卡如何驱动

linux下无线网卡具体驱动的操作方法如下：

1、首先需要确定网卡的类型，打开linux的输入窗口，然后继续在linux终端下输入lsusb命令，此时在输出栏的第一行可以查看网卡类型，记录下来。

C. 在LINUX中如何加载驱动网卡

显卡安装：
一、下载驱动程序
首先要找到显卡for
Linux的驱动程序。现在绝大多数的3D显卡都已有了for
Linux的驱动程序，可到各显卡厂商的主页或Linux的相关站点上去寻找。在安装显卡时，服务器根据显卡的情况来加载不同的显示模块，如果显示模块加载不正确，显卡就不能正常显示。
二、装载磁盘驱动器
Linux需要装载磁盘驱动器才能读取文件。启动Linux后，在字符界面下输入“mount
－t
vfat
/dev/hda1
/mnt/winc”命令，将C盘装载到Linux下。需要注意的是，如果下载的是压缩文件，选择的是在Linux下解压，就得先进行装载磁盘驱动器这一步，再进行文件的解压缩。
三、拷贝文件
将XF86_SVGA文件拷贝到/usr/X11R6/bin目录下。注意，这是针对Red
Hat版本来说，其它版本的路径不一定相同。“cp
/mnt/winc/win98/TEMP/XF86_SVGA
/usr/X11R6/bin”(根据自己的情况灵活掌握，关键是路径一定要正确，还要分清字母的大小写)。如果系统提示有同名文件，问是否覆盖，一定要选择“y”。这些旧文件可能是以前安装显卡时加载的，没有实际用处。在输入文件名的时候，输完XF86后按一下Tab键，再接着输SVGA，下划线_就可以出来了，按键盘上的下划线键是没用的，切记。
四、配置显卡
文件拷贝完成后，输入Xconfigurator，启动显卡配置程序。我在显卡列表中仍然没有找到Trident
Blade
3D，于是选最后一个选项“Unlist”，然后选择加载的显示模块为SVGA，再选择显示器型号、显存大小、刷新频率
总结：在Linux下安装显卡驱动程序，首先要下载显卡支持Linux的驱动程序，再将其拷贝到/usr/X11R6/bin目录下，然后启动显卡配置程序进行配置即可。
网卡、声卡等驱动安装可以依此类推
