39 To compile this driver into the kernel,
40 place the following line in your
41 kernel configuration file:

47 module at boot time, place the following line in

123 Farallon EtherWave and EtherMac PC Card (P/n 595/895 with BLUE arrow)
126 The 3c509 card has no jumpers to set the address.
127 3Com supplies software to set the address of the card in software.
128 To find the card on the ISA bus, the kernel performs a complex
129 scan operation at IO address 0x110.
131 Avoid placing other cards at that address!
134 the 3c509 should only
135 be configured in EISA mode
136 when installed in a computer that has actual EISA slots
137 (and an EISA-aware BIOS).
138 The normal driver auto-detection support
139 is sufficient for non-EISA systems.
141 Many different companies sold the 3Com PC Cards under their own private
143 These cards also work.
145 The Farallon EtherWave and EtherMac card came in two varieties.
148 driver supports the 595 and 895 cards.
149 These cards have the blue arrow on the front along with a 3Com logo.
150 The Farallon 595a cards, which have a red arrow on the front,
151 are also called EtherWave and EtherMac.
152 They are supported by the
157 .It "ep0: reset (status: %x)"
158 The driver has encountered a FIFO underrun or overrun.
159 The driver will reset the card and the packet will be lost.
161 .It "ep0: eeprom failed to come ready"
162 The eeprom failed to come ready.
163 This probably means the card is wedged.
164 .It "ep0: 3c509 in test mode. Erase pencil mark!"
165 This means that someone has scribbled with pencil
166 in the test area on the card.
167 Erase the pencil mark and reboot.
168 (This is not a joke).
169 .It "ep0: No I/O space?!"
170 The driver was unable to allocate the I/O space that it thinks
172 Look for conflicts with other devices.
174 The driver could not allocate the interrupt it wanted.
175 Look for conflicts, although sharing interrupts for PC Card is normal.
176 .It "ep0: No connectors!"
177 The driver queried the hardware for what ethernet attachment were
178 present, but the hardware reported none that the driver recognized.
179 .It "ep0: Unable to get Ethernet address!"
180 The driver was unable to read the ethernet address from the EEPROM.
181 This is likely the result of the card being wedged.
182 .It "ep0: if_alloc() failed"
183 The driver was unable to allocate a ifnet structure.
184 This may happen in extremely low memory conditions.
185 .It "ep0: strange connector type in EEPROM: assuming AUI"
186 The driver does not know what to do with the information the EEPROM
187 has about connectors, so it is assuming the worst.
188 .It "ep0: unknown ID 0xXXXXXXXX"
189 The driver has found an ID that it believes it supports, but does not
190 have a specific identification string to present to the user.
191 .It "ep0: <%s> at port 0x%03x in EISA mode"
192 The 3C509 ISA card is in EISA mode.
193 This message appears to be purely informational.
194 .It "ep0: <%s> at x0%03x in PnP mode"
195 This card appears to be in Plug and Play mode.
196 It should be probed as part of the plug and play phase of the ISA
198 .It "ep0: Invalid EEPROM checksum!"
199 The EEPROM has a bad checksum, so the driver is ignoring the card.
200 .It "ep0: bus_setup_intr() failed!"
201 The driver was unable to setup the interrupt handler.
202 This should never happen.
215 There is so many to choose from.
217 Support for the 3Com 3C1 is not working.
