.Sh NAME
|
|
.Nm ep
|
|
.Nd "Ethernet driver for 3Com Etherlink III (3c5x9) interfaces"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ep"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_ep_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver supports network adapters based on the 3Com 3C5x9 Etherlink III
|
|
Parallel Tasking chipset.
|
|
.Pp
|
|
Various models of these cards come with a different assortment of
|
|
connectors:
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It AUI/DIX
|
|
Standard 15 pin connector, also known as 10base5 (thick-net)
|

|
|
.It 10BaseT
|
|
UTP, also known as twisted pair
|
|
.El
|
|
.Pp
|
|
The default port to use is the port that has been selected with the
|
|
setup utility.
|
|
To override this, use the following media options with
|
|
.Xr ifconfig 8
|
|
or in your
|
|
.Pa /etc/rc.conf
|
|
file.
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It 10base5/AUI
|
|
Use the AUI port.
|
|
.It 10base2/BNC
|
|

Farallon EtherWave and EtherMac PC Card (P/n 595/895 with BLUE arrow)
|
|
.El
|
|
.Sh NOTES
|
|
The 3c509 card has no jumpers to set the address.
|
|
3Com supplies software to set the address of the card in software.
|
|
To find the card on the ISA bus, the kernel performs a complex
|
|
scan operation at IO address 0x110.
|
|
Beware!
|
|
Avoid placing other cards at that address!
|
|
.Pp
|
|
Furthermore, the 3c509 should only be configured in EISA mode
|
|
when installed in a computer that has actual EISA slots
|
|
(and an EISA-aware BIOS).
|
|
The normal driver auto-detection support is sufficient for non-EISA systems.
|
|
.Pp
|
|
Cards in PnP mode may conflict with other resources in the system.
|
|
Ensure your BIOS is configured correctly to exclude resources used by
|
|
the 3c509, especially IRQs, to avoid unpredictable behavior.
|
|
.Pp
|
|
Many different companies sold the 3Com PC Cards under their own private
|
|
label.
|
|
These cards also work.
|
|
.Pp
|
|
The Farallon EtherWave and EtherMac card came in two varieties.
|
|
The
|
|
.Nm
|
|
driver supports the 595 and 895 cards.
|
|
These cards have the blue arrow on the front along with a 3Com logo.
|
|
The Farallon 595a cards, which have a red arrow on the front,
|
|
are also called EtherWave and EtherMac.
|
|
They are supported by the
|
|
.Xr sn 4
|
|
driver.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "ep0: reset (status: %x)"
|
|
The driver has encountered a FIFO underrun or overrun.
|
|
The driver will reset the card and the packet will be lost.
|
|
This is not fatal.
|
|
.It "ep0: eeprom failed to come ready"
|
|
The eeprom failed to come ready.
|
|
This probably means the card is wedged.
|
|
.It "ep0: 3c509 in test mode. 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.
