37 .Nd "Ethernet driver for 3Com Etherlink III (3c5x9) interfaces"
39 To compile support for the
41 driver into your kernel, place the following line in your
42 kernel configuration file:
43 .Bd -ragged -offset indent
47 Alternatively, to load the
49 driver at boot time, place the following line in
51 .Bd -literal -offset indent
57 device driver supports network adapters based on the 3Com 3C5x9 Etherlink III
58 Parallel Tasking chipset.
60 Various models of these cards come with a different assortment of
63 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
65 Standard 15 pin connector, also known as 10base5 (thick-net)
67 BNC, also known as thin-net
69 UTP, also known as twisted pair
72 The default port to use is the port that has been selected with the
74 To override this, use the following media options with
80 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
89 If there are multiple cards in the computer, they are searched for
90 in the following order: bus, slot, then Ethernet address.
94 driver supports Ethernet adapters based on the
95 3Com 3C5x9 Etherlink III Parallel Tasking chipset, including:

125 Farallon EtherWave and EtherMac PC Card (P/n 595/895 with BLUE arrow)
128 The 3c509 card has no jumpers to set the address.
129 3Com supplies software to set the address of the card in software.
130 To find the card on the ISA bus, the kernel performs a complex
131 scan operation at IO address 0x110.
133 Avoid placing other cards at that address!
136 the 3c509 should only
137 be configured in EISA mode
138 when installed in a computer that has actual EISA slots
139 (and an EISA-aware BIOS).
140 The normal driver auto-detection support
141 is sufficient for non-EISA systems.
143 Many different companies sold the 3Com PC Cards under their own private
145 These cards also work.
147 The Farallon EtherWave and EtherMac card came in two varieties.
150 driver supports the 595 and 895 cards.
151 These cards have the blue arrow on the front along with a 3Com logo.
152 The Farallon 595a cards, which have a red arrow on the front,
153 are also called EtherWave and EtherMac.
154 They are supported by the
159 .It ep0: reset (status: %x)
160 The driver has encountered a FIFO underrun or overrun.
161 The driver will reset the card and the packet will be lost.
163 .It ep0: eeprom failed to come ready
164 The eeprom failed to come ready.
165 This probably means the card is wedged.
166 .It ep0: 3c509 in test mode. Erase pencil mark!
167 This means that someone has scribbled with pencil
168 in the test area on the card.
169 Erase the pencil mark and reboot.
170 (This is not a joke).
171 .It ep0: No I/O space?!
172 The driver was unable to allocate the I/O space that it thinks
174 Look for conflicts with other devices.
176 The driver couldn't allocate the interrupt it wanted.
177 Look for conflicts, although sharing interrupts for PC Card is normal.
178 .It ep0: No connectors!
179 The driver queried the hardware for what ethernet attachment were
180 present, but the hardware reported none that the driver recognized.
181 .It ep0: Unable to get Ethernet address!
182 The driver was unable to read the ethernet address from the EEPROM.
183 This is likely the result of the card being wedged.
184 .It ep0: if_alloc() failed
185 The driver was unable to allocate a ifnet structure.
186 This may happen in extremely low memory conditions.
187 .It ep0: strange connector type in EEPROM: assuming AUI
188 The driver does not know what to do with the information the EEPROM
189 has about connectors, so it is assuming the worst.
190 .It ep0: unknown ID 0xXXXXXXXX
191 The driver has found an ID that it believes it supports, but doesn't
192 have a specific identification string to present to the user.
193 .It ep0: <%s> at port 0x%03x in EISA mode
194 The 3C509 ISA card is in EISA mode.
195 This message appears to be purely informational.
196 .It ep0: <%s> at x0%03x in PnP mode
197 This card appears to be in Plug and Play mode.
198 It should be probed as part of the plug and play phase of the ISA
200 .It ep0: Invalid EEPROM checksum!
201 The EEPROM has a bad checksum, so the driver is ignoring the card.
202 .It ep0: bus_setup_intr() failed!
203 The driver was unable to setup the interrupt handler.
204 This should never happen.
216 There is so many to choose from.
218 Support for the 3Com 3C1 is not working.
