472. Supported adapters
48=====================
49
50The network driver 'skfp' supports the following network adapters:
51SysKonnect adapters:
52
53  - SK-5521 (SK-NET FDDI-UP)
54  - SK-5522 (SK-NET FDDI-UP DAS)
55  - SK-5541 (SK-NET FDDI-FP)
56  - SK-5543 (SK-NET FDDI-LP)
57  - SK-5544 (SK-NET FDDI-LP DAS)
58  - SK-5821 (SK-NET FDDI-UP64)
59  - SK-5822 (SK-NET FDDI-UP64 DAS)
60  - SK-5841 (SK-NET FDDI-FP64)
61  - SK-5843 (SK-NET FDDI-LP64)
62  - SK-5844 (SK-NET FDDI-LP64 DAS)
63
64Compaq adapters (not tested):
65
66  - Netelligent 100 FDDI DAS Fibre SC
67  - Netelligent 100 FDDI SAS Fibre SC
68  - Netelligent 100 FDDI DAS UTP
69  - Netelligent 100 FDDI SAS UTP
70  - Netelligent 100 FDDI SAS Fibre MIC
71
72
733. General Information
74======================
75
76From v2.01 on, the driver is integrated in the linux kernel sources.
77Therefore, the installation is the same as for any other adapter
78supported by the kernel.
79
80Refer to the manual of your distribution about the installation
81of network adapters.
82
83Makes my life much easier :-)
84
854. Troubleshooting
86==================
87
88If you run into problems during installation, check those items:
89
90Problem:
91	  The FDDI adapter cannot be found by the driver.
92
93Reason:
94	  Look in /proc/pci for the following entry:
95
96	     'FDDI network controller: SysKonnect SK-FDDI-PCI ...'
97
98	  If this entry exists, then the FDDI adapter has been
99	  found by the system and should be able to be used.
100
101	  If this entry does not exist or if the file '/proc/pci'
102	  is not there, then you may have a hardware problem or PCI
103	  support may not be enabled in your kernel.
104
105	  The adapter can be checked using the diagnostic program
106	  which is available from the SysKonnect web site:
107
108	      www.syskonnect.de
109
110	  Some COMPAQ machines have a problem with PCI under
111	  Linux. This is described in the 'PCI howto' document
112	  (included in some distributions or available from the
113	  www, e.g. at 'www.linux.org') and no workaround is available.
114
115Problem:
116	  You want to use your computer as a router between
117	  multiple IP subnetworks (using multiple adapters), but
118	  you cannot reach computers in other subnetworks.
119
120Reason:
121	  Either the router's kernel is not configured for IP
122	  forwarding or there is a problem with the routing table
123	  and gateway configuration in at least one of the
124	  computers.
125
126If your problem is not listed here, please contact our
127technical support for help.
128
129You can send email to: linux@syskonnect.de
130
131When contacting our technical support,
132please ensure that the following information is available:
133
134- System Manufacturer and Model
135- Boards in your system
136- Distribution
137- Kernel version

1405. Function of the Adapter LEDs
141===============================
142
143	The functionality of the LED's on the FDDI network adapters was
144	changed in SMT version v2.82. With this new SMT version, the yellow
145	LED works as a ring operational indicator. An active yellow LED
146	indicates that the ring is down. The green LED on the adapter now
147	works as a link indicator where an active GREEN LED indicates that
148	the respective port has a physical connection.
149
150	With versions of SMT prior to v2.82 a ring up was indicated if the
151	yellow LED was off while the green LED(s) showed the connection
152	status of the adapter. During a ring down the green LED was off and
153	the yellow LED was on.
154
155	All implementations indicate that a driver is not loaded if
156	all LEDs are off.
