(1) OVERVIEW
============

This README explains how to use the driver 'skfp' for Linux with your
network adapter.

Chapter 2: Contains a list of all network adapters that are supported by
	   this driver.

Chapter 3: Gives some general information.

Chapter 4: Describes common problems and solutions.

Chapter 5: Shows the changed functionality of the adapter LEDs.

Chapter 6: History of development.

(2) SUPPORTED ADAPTERS
======================

The network driver 'skfp' supports the following network adapters:
SysKonnect adapters:
  - SK-5521 (SK-NET FDDI-UP)
  - SK-5522 (SK-NET FDDI-UP DAS)
  - SK-5541 (SK-NET FDDI-FP)
  - SK-5543 (SK-NET FDDI-LP)
  - SK-5544 (SK-NET FDDI-LP DAS)
  - SK-5821 (SK-NET FDDI-UP64)
  - SK-5822 (SK-NET FDDI-UP64 DAS)
  - SK-5841 (SK-NET FDDI-FP64)
  - SK-5843 (SK-NET FDDI-LP64)
  - SK-5844 (SK-NET FDDI-LP64 DAS)
Compaq adapters (not tested):
  - Netelligent 100 FDDI DAS Fibre SC
  - Netelligent 100 FDDI SAS Fibre SC
  - Netelligent 100 FDDI DAS UTP
  - Netelligent 100 FDDI SAS UTP
  - Netelligent 100 FDDI SAS Fibre MIC
***


(3) GENERAL INFORMATION
=======================

From v2.01 on, the driver is integrated in the linux kernel sources.
Therefor, the installation is the same as for any other adapter
supported by the kernel.
Refer to the manual of your distribution about the installation
of network adapters.
Makes my life much easier :-)
***


(4) TROUBLESHOOTING
===================

If you run into problems during installation, check those items:

Problem:  The FDDI adapter can not be found by the driver.
Reason:   Look in /proc/pci for the following entry:
             'FDDI network controller: SysKonnect SK-FDDI-PCI ...'
	  If this entry exists, then the FDDI adapter has been
	  found by the system and should be able to be used.
	  If this entry does not exist or if the file '/proc/pci'
	  is not there, then you may have a hardware problem or PCI
	  support may not be enabled in your kernel.
	  The adapter can be checked using the diagnostic program
	  which is available from the SysKonnect web site:
	      www.syskonnect.de
	  Some COMPAQ machines have a problem with PCI under
	  Linux. This is described in the 'PCI howto' document
	  (included in some distributions or available from the
	  www, e.g. at 'www.linux.org') and no workaround is available.

Problem:  You want to use your computer as a router between
          multiple IP subnetworks (using multiple adapters), but
	  you can not reach computers in other subnetworks.
Reason:   Either the router's kernel is not configured for IP
	  forwarding or there is a problem with the routing table
	  and gateway configuration in at least one of the
	  computers.

If your problem is not listed here, please contact our
technical support for help. 
You can send email to:
  linux@syskonnect.de
When contacting our technical support,
please ensure that the following information is available:
- System Manufacturer and Model
- Boards in your system
- Distribution
- Kernel version

(5) FUNCTION OF THE ADAPTER LEDS
================================

        The functionality of the LED's on the FDDI network adapters was
        changed in SMT version v2.82. With this new SMT version, the yellow
        LED works as a ring operational indicator. An active yellow LED
        indicates that the ring is down. The green LED on the adapter now
        works as a link indicator where an active GREEN LED indicates that
        the respective port has a physical connection.

        With versions of SMT prior to v2.82 a ring up was indicated if the
        yellow LED was off while the green LED(s) showed the connection
        status of the adapter. During a ring down the green LED was off and
        the yellow LED was on.

        All implementations indicate that a driver is not loaded if
        all LEDs are off.
