Erase pencil mark!" +This means that someone has scribbled with pencil +in the test area on the card. +Erase the pencil mark and reboot. +(This is not a joke). +.It "ep0: No I/O space?!" +The driver was unable to allocate the I/O space that it thinks +should be there. +Look for conflicts with other devices. +.It "ep0: No irq?!" +The driver could not allocate the interrupt it wanted. +Look for conflicts, although sharing interrupts for PC Card is normal. +.It "ep0: No connectors!" +The driver queried the hardware for what ethernet attachment were +present, but the hardware reported none that the driver recognized. +.It "ep0: Unable to get Ethernet address!" +The driver was unable to read the ethernet address from the EEPROM. +This is likely the result of the card being wedged. +.It "ep0: if_alloc() failed" +The driver was unable to allocate a ifnet structure. +This may happen in extremely low memory conditions. +.It "ep0: strange connector type in EEPROM: assuming AUI" +The driver does not know what to do with the information the EEPROM +has about connectors, so it is assuming the worst. +.It "ep0: unknown ID 0xXXXXXXXX" +The driver has found an ID that it believes it supports, but does not +have a specific identification string to present to the user. +.It "ep0: <%s> at port 0x%03x in EISA mode" +The 3C509 ISA card is in EISA mode. +This message appears to be purely informational. +.It "ep0: <%s> at x0%03x in PnP mode" +This card appears to be in Plug and Play mode. +It should be probed as part of the plug and play phase of the ISA +probes. +.It "ep0: Invalid EEPROM checksum!" +The EEPROM has a bad checksum, so the driver is ignoring the card. +.It "ep0: bus_setup_intr() failed!" +The driver was unable to setup the interrupt handler. +This should never happen. +.El +.Sh SEE ALSO +.Xr altq 4 , +.Xr ed 4 , +.Xr el 4 , +.Xr ie 4 , +.Xr intro 4 , +.Xr ng_ether 4 , +.Xr sn 4 , +.Xr vx 4 , +.Xr ifconfig 8 +.Sh STANDARDS +are great. +There is so many to choose from. |
