118 Farallon EtherWave and EtherMac PC Card (P/n 595/895 with BLUE arrow)
121 The 3c509 card has no jumpers to set the address.
122 3Com supplies software to set the address of the card in software.
123 To find the card on the ISA bus, the kernel performs a complex
124 scan operation at IO address 0x110.
126 Avoid placing other cards at that address!
128 Furthermore, the 3c509 should only be configured in EISA mode
129 when installed in a computer that has actual EISA slots
130 (and an EISA-aware BIOS).
131 The normal driver auto-detection support is sufficient for non-EISA systems.
133 Cards in PnP mode may conflict with other resources in the system.
134 Ensure your BIOS is configured correctly to exclude resources used by
135 the 3c509, especially IRQs, to avoid unpredictable behavior.
137 Many different companies sold the 3Com PC Cards under their own private
139 These cards also work.
141 The Farallon EtherWave and EtherMac card came in two varieties.
144 driver supports the 595 and 895 cards.
145 These cards have the blue arrow on the front along with a 3Com logo.
146 The Farallon 595a cards, which have a red arrow on the front,
147 are also called EtherWave and EtherMac.
148 They are supported by the
153 .It "ep0: reset (status: %x)"
154 The driver has encountered a FIFO underrun or overrun.
155 The driver will reset the card and the packet will be lost.
157 .It "ep0: eeprom failed to come ready"
158 The eeprom failed to come ready.
159 This probably means the card is wedged.
160 .It "ep0: 3c509 in test mode. Erase pencil mark!"
161 This means that someone has scribbled with pencil
162 in the test area on the card.
163 Erase the pencil mark and reboot.
164 (This is not a joke).
165 .It "ep0: No I/O space?!"
166 The driver was unable to allocate the I/O space that it thinks
168 Look for conflicts with other devices.
170 The driver could not allocate the interrupt it wanted.
171 Look for conflicts, although sharing interrupts for PC Card is normal.
172 .It "ep0: No connectors!"
173 The driver queried the hardware for what ethernet attachment were
174 present, but the hardware reported none that the driver recognized.
175 .It "ep0: Unable to get Ethernet address!"
176 The driver was unable to read the ethernet address from the EEPROM.
177 This is likely the result of the card being wedged.
178 .It "ep0: if_alloc() failed"
179 The driver was unable to allocate a ifnet structure.
180 This may happen in extremely low memory conditions.
181 .It "ep0: strange connector type in EEPROM: assuming AUI"
182 The driver does not know what to do with the information the EEPROM
183 has about connectors, so it is assuming the worst.
184 .It "ep0: unknown ID 0xXXXXXXXX"
185 The driver has found an ID that it believes it supports, but does not
186 have a specific identification string to present to the user.
187 .It "ep0: <%s> at port 0x%03x in EISA mode"
188 The 3C509 ISA card is in EISA mode.
189 This message appears to be purely informational.
190 .It "ep0: <%s> at x0%03x in PnP mode"
191 This card appears to be in Plug and Play mode.
192 It should be probed as part of the plug and play phase of the ISA
194 .It "ep0: Invalid EEPROM checksum!"
195 The EEPROM has a bad checksum, so the driver is ignoring the card.
196 .It "ep0: bus_setup_intr() failed!"
197 The driver was unable to setup the interrupt handler.
198 This should never happen.
212 There is so many to choose from.
