Allied Telesyn AT-2450/2700 Series PCI Ethernet Adapter

Linux driver version 1.30i-ATI README

The atnic32 driver supports Allied Telesyn AT-2450/2700 Series PCI
Ethernet Adapter cards. The inclosed object file was compiled using
the 2.4.18-3 kernel.

The driver has to be re-compiled if it is run under a different 
Kernel version. See the section on compiling the source code for
instructions.

Note: You must remove the pcnet32 module which is automatically
      loaded by the hardware detection mechanism in order to use
      this driver. Since the AT-2450 and AT-2700 Series NICs use
      the AMD Am79C972 (Fast+) and Am79C976 chipsets, AMD's driver
      is automatically loaded by the OS.

Expanding the Driver Package:
-----------------------------
1. Copy the gzip file to a temporary directory on the Linux system.

2. type "gunzip <filename>", where filename is the name of the driver package.
   This will decompress the tar file.

3. type "tar -xvf <filename>", where filename is the name of the tar file
   extracted in the previous step. This will extract the driver files
   from the tar file.

Compiling the source code:
--------------------------
1. Install the kernel source files from the Linux distribution CDs.

2. Type "make clean" to remove the current object file.

3. Type "make" to build the object file (driver). You should end up with
   a file called "atnic32.o", when successfull.

4. Proceed with driver installation.

Driver Installation:
--------------------
Note: If you see unresolved symbol messages when loading the driver, you
      must re-compile it for the current kernel version.

1. Install the driver module using the following command:

   make install

2. Edit the etc/modules.conf file to change the alias for ethX, where x
   represents the adapter instance. For example:

   alias eth0 pcnet32

   change to:

   alias eth0 atnic32

3. Reboot the system for the changes to take effect.


Changing Configuration Settings
-----------------------------------------------------------------------------
To enable "Auto Negotiation" edit the /etc/modules.conf file to 
add the line "options atnic32 speed_duplex=0" below the "alias eth0 atnic32" 
line. The table below shows the various options for changing speed and
duplex, and forcing the active port in the case of the combo boards. Only
ONE of the following lines can be added. Only one interface is activated based
on the keyword it represents. If neither option is selected the driver/device 
defaults to the hardware setting. Each option is selected by the number 
it represents.

AT-2450F, AT-2450FTX, AT-2700TX, AT-2700/2701FX, AT-2745FX, AT-2700FTX
(AMD Am79C972 - Fast+ chipset):
------------------------------------------------------------------
options atnic32 speed_duplex=0	#use hardware settings
options atnic32 speed_duplex=1	#100Mbps, Half duplex
options atnic32 speed_duplex=2  #100Mbps, Full duplex
options atnic32 speed_duplex=3	#10Mbps, Half duplex
options atnic32 speed_duplex=4	#10Mbps, Full duplex
options atnic32 speed_duplex=5  #Auto Negotiation

Example:
--------
alias eth0 atnic32
options atnic32 speed_duplex=3

This entry will override the hardware setting and enable 10Mb / half
duplex mode.

Example:

alias eth0 atnic32
options atnic32 speed_duplex=0 

I addition to speed_duplex, default_port is also configurable.
default_port
-------------------------------------------------------------------

options atnic32 default_port=1 #  Uses primary port, 100Mb Fiber(2701FTX) or 10MB Fiber(2451FTX)
options atnic32 default_port=2 #  Uses secondary port, 10mb Fiber(2450FTX), Copper(2701FTX, 2451FTX)

If using both speed_duplex and default_port, both keywords must be on the same
line of the modules.conf as in the following example:

Example:
--------

options atnic32 speed_duplex=2 default_port=1 #  AT2701FTX to 100Mb Full duplex, primary port(fiber)



LEGACY
-----------------------------------------------------------------------
The following entry will over-ride the hardware setting for speed and duplex and
force the dirver to use the secondary media port.

AT-2450FT (legacy PCI using Am79C970 and Am79C971
-------------------------------------------------------------------
options atnic32 full_duplex=1

This setting will override the hardware setting and enable full duplex.
