-.Os
-.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 DEPRECATION NOTICE
-The
-.Nm
-driver is not present in
-.Fx 13.0
-and later.
-See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more
-information.
-.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 10Base2
-BNC, also known as thin-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
-Use the BNC port.
-.It 10baseT/UTP
-Use the UTP port.
-.El
-.Sh HARDWARE

-.It
-3Com OfficeConnect 3CXSH572BT, 3CCSH572BT PCMCIA
-.It
-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 not be configured in EISA mode.
-.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, ignored."
-The 3C509 ISA card is in EISA mode.
-The card will be ignored until it is taken out of EISA mode.
-.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.

-.Sh STANDARDS
-are great.
-There is so many to choose from.
