43(2) SUPPORTED ADAPTERS
44======================
45
46The network driver 'skfp' supports the following network adapters:
47SysKonnect adapters:
48  - SK-5521 (SK-NET FDDI-UP)
49  - SK-5522 (SK-NET FDDI-UP DAS)
50  - SK-5541 (SK-NET FDDI-FP)
51  - SK-5543 (SK-NET FDDI-LP)
52  - SK-5544 (SK-NET FDDI-LP DAS)
53  - SK-5821 (SK-NET FDDI-UP64)
54  - SK-5822 (SK-NET FDDI-UP64 DAS)
55  - SK-5841 (SK-NET FDDI-FP64)
56  - SK-5843 (SK-NET FDDI-LP64)
57  - SK-5844 (SK-NET FDDI-LP64 DAS)
58Compaq adapters (not tested):
59  - Netelligent 100 FDDI DAS Fibre SC
60  - Netelligent 100 FDDI SAS Fibre SC
61  - Netelligent 100 FDDI DAS UTP
62  - Netelligent 100 FDDI SAS UTP
63  - Netelligent 100 FDDI SAS Fibre MIC

67(3) GENERAL INFORMATION
68=======================
69
70From v2.01 on, the driver is integrated in the linux kernel sources.
71Therefore, the installation is the same as for any other adapter
72supported by the kernel.
73Refer to the manual of your distribution about the installation
74of network adapters.
75Makes my life much easier :-)

79(4) TROUBLESHOOTING
80===================
81
82If you run into problems during installation, check those items:
83
84Problem: The FDDI adapter cannot be found by the driver.
85Reason: Look in /proc/pci for the following entry:
86             'FDDI network controller: SysKonnect SK-FDDI-PCI ...'
87      If this entry exists, then the FDDI adapter has been
88      found by the system and should be able to be used.
89      If this entry does not exist or if the file '/proc/pci'
90      is not there, then you may have a hardware problem or PCI
91      support may not be enabled in your kernel.
92      The adapter can be checked using the diagnostic program
93      which is available from the SysKonnect web site:
94          www.syskonnect.de
95      Some COMPAQ machines have a problem with PCI under
96      Linux. This is described in the 'PCI howto' document
97      (included in some distributions or available from the
98      www, e.g. at 'www.linux.org') and no workaround is available.
99
100Problem: You want to use your computer as a router between
101          multiple IP subnetworks (using multiple adapters), but
102      you cannot reach computers in other subnetworks.
103Reason: Either the router's kernel is not configured for IP
104      forwarding or there is a problem with the routing table
105      and gateway configuration in at least one of the
106      computers.
107
108If your problem is not listed here, please contact our
109technical support for help.
110You can send email to:
111  linux@syskonnect.de
112When contacting our technical support,
113please ensure that the following information is available:
114- System Manufacturer and Model
115- Boards in your system
116- Distribution
117- Kernel version

122(5) FUNCTION OF THE ADAPTER LEDS
123================================
124
125        The functionality of the LED's on the FDDI network adapters was
126        changed in SMT version v2.82. With this new SMT version, the yellow
127        LED works as a ring operational indicator. An active yellow LED
128        indicates that the ring is down. The green LED on the adapter now
129        works as a link indicator where an active GREEN LED indicates that
130        the respective port has a physical connection.
131
132        With versions of SMT prior to v2.82 a ring up was indicated if the
133        yellow LED was off while the green LED(s) showed the connection
134        status of the adapter. During a ring down the green LED was off and
135        the yellow LED was on.
136
137        All implementations indicate that a driver is not loaded if
138        all LEDs are off.
