37 .Nd Ethernet driver for 3Com Etherlink III (3c5x9) interfaces
43 device driver supports network adapters based on the 3Com 3C5x9 Etherlink III
44 Parallel Tasking chipset.
46 Various models of these cards come with a different assortment of
49 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
51 Standard 15 pin connector, also known as 10base5 (thick-net)
53 BNC, also known as thin-net
55 UTP, also known as twisted pair
58 The default port to use is the port that has been selected with the
60 To override this, use the following media options with
66 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
75 If there are multiple cards in the computer, they are searched for
76 in the following order: bus, slot, then Ethernet address.
80 driver supports Ethernet adapters based on the
81 3Com 3C5x9 Etherlink III Parallel Tasking chipset, including:
87 3Com 3C509-TP, 3C509-BNC, 3C509-Combo, 3C509-TPO, 3C509-TPC ISA
89 3Com 3C509B-TP, 3C509B-BNC, 3C509B-Combo, 3C509B-TPO, 3C509B-TPC ISA

109 3Com OfficeConnect 3CXSH572BT, 3CCSH572BT PCMCIA
112 The 3c509 card has no jumpers to set the address.
113 3Com supplies software to set the address of the card in software.
114 To find the card on the ISA bus, the kernel performs a complex
115 scan operation at IO address 0x110.
117 Avoid placing other cards at that address!
120 the 3c509 should only
121 be configured in EISA mode
122 when installed in a computer that has actual EISA slots
123 (and an EISA-aware BIOS).
124 The normal driver auto-detection support
125 is sufficient for non-EISA systems.
127 Many different companies sold the 3Com PC Cards under their own private
129 These cards also work.
132 .It ep0: reset (status: %x)
133 The driver has encountered a FIFO underrun or overrun.
134 The driver will reset the card and the packet will be lost.
136 .It ep0: eeprom failed to come ready
137 The eeprom failed to come ready.
138 This probably means the card is wedged.
139 .It ep0: 3c509 in test mode. Erase pencil mark!
140 This means that someone has scribbled with pencil
141 in the test area on the card.
142 Erase the pencil mark and reboot.
143 (This is not a joke).
144 .It ep0: No I/O space?!
145 The driver was unable to allocate the I/O space that it thinks
147 Look for conflicts with other devices.
149 The driver couldn't allocate the interrupt it wanted.
150 Look for conflicts, although sharing interrupts for PC Card is normal.
151 .It ep0: No connectors!
152 The driver querried the hardware for what ethernet attachment were
153 present, but the hardware reported none that the driver recognized.
154 .It ep0: Unable to get Ethernet address!
155 The driver was unabel to read the ethernet address from the EEPROM.
156 This is likely the result of the card being wedged.
157 .It ep0: if_alloc() failed
158 The driver was unable to allocate a ifnet structure.
159 This may happen in extremely low memory conditions.
160 .It ep0: strange connector type in EEPROM: assuming AUI
161 The driver does not know what to do with the information the EEPROM
162 has about connectors, so it is assuming the worst.
163 .It ep0: unknown ID 0xXXXXXXXX
164 The driver has found an ID that it believes it supports, but doesn't
165 have a specific identification string to present to the user.
166 .It ep0: <%s> at port 0x%03x in EISA mode
167 The 3C509 ISA card is in EISA mode.
168 This message appears to be purely informational.
169 .It ep0: <%s> at x0%03x in PnP mode
170 This card appears to be in Plug and Play mode.
171 It should be probed as part of the plug and play phase of the ISA
173 .It ep0: Invalid EEPROM checksum!
174 The EEPROM has a bad checksum, so the driver is ignoring the card.
175 .It ep0: bus_setup_intr() failed!
176 The driver was unable to setup the interrupt handler.
177 This should never happen.
189 There is so many to choose from.
191 Support for the 3Com 3C1 is not working.
