Device Usage :
---------------------
The openpci_8139.device is a SANA2 Device that works with MiamiDx,
Genesis(AmiTCP) and possibly other TCP/IP stacks.

Requirement : 
---------------------
This device requires openpci.library v2.1 or later.
See OpenPCI documentation for more information about PCI Buss support.

Limitation : 
---------------------
The device can handle only one Unit (Unit 0).
I plan to add multi-unit support to a future version.

Config File Usage :
---------------------
The config File name is openpci_8139_x.config
The "x" is the Unit number used in your TCP/IP stack (by default 0).
Config file value :
0=Speed Auto Negociation 
1=10Mb Half-Duplex
2=10Mb Full-Duplex
3=100Mb Half-Duplex
4=100Mb Full-Duplex
To change the specific speed, just change the value at the top of the file.

You don't need to reboot each time you change this value. In fact you just need
to stop your TCP/IP stack, flush the device (type : avail flush), and restart the Device.

Device driver Install:
----------------------
For MorphOS users:
Use the native PPC MOS version openpci_8139.device.elf
- copy openpci_8139.device.elf to mossys:devs/networks/openpci_8139.device
Be careful. It must be copied as openpci_8139.device, because if it's called 
openpci_8139.device.elf it will not work.

For AmigaOS users:
Use the 68k version openpci_8139.device
- copy openpci_8139.device to devs:networks/openpci_8139.device

Config File Install :
---------------------
- make a dir OpenPCI in Envarc: if it doesn't exist
- copy the file openpci_8139_0.config to Envarc:OpenPCI/

Network Auto Negotiation Warning :
---------------------
Auto Negotiation mode is the default configuration for openpci_8139.device.
The Auto Negotiation mode detects the speed of your local network and sets
the 8139 Chipset speed to 10Mb or 100Mb. Auto Negotiation is all done by the
hardware and always at Half-Duplex. But sometimes the Auto Negotiation could
fail to detect the proper the network speed and could detect 100Mb when the
network is actually 10Mb. If this happens, nothing will work and you will see
99% packet loss. If you see this problem on your network, then manually set
the network speed to 10Mb in the config file.

Full-Duplex Warning :
---------------------
If you try to use Full-Duplex on a network with a Hub, your network will not
work very well. It's not possible to use Full-Duplex mode with a Hub. Enable
Full-Duplex only if you use a Switch or a direct link through two 10/100Mb Cards.

This warning is necessay because of the 8139A/B/C/D chipsets and not due
the the openpci_8139.device driver.
