This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

.Sh NAME
|
|
.Nm ep
|
|
.Nd Ethernet driver for 3Com Etherlink III (3c5x9)
|
|
.Sh SYNOPSIS
|
|
.Cd "device ep0 at isa? port 0x300 net irq 10 vector epintr"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm ep
|
|
device driver supports the 3c509 (ISA) and 3c579 (EISA) cards.
|
|
Various models of these cards come with a different assortment of
|
|
connectors:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It AUI/DIX
|
|
Standard 15 pin connector
|
|
.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 BNC. To choose an alternate port,
|
|
use the following flag combinations with
|
|
.Xr ifconfig 8
|
|
or in your /etc/hostname.ep? file.
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It -link0
|
|
Use the BNC port (default).
|
|
.It \ link0 -link1
|
|
Use the AUI port.
|
|
.It \ link0 \ link1
|
|
Use the UTP port.
|
|
.El
|
|
.Pp
|
|
If there are multiple cards in the computer, they are searched for
|
|
in the following order:
|
|
The 3c579 EISA cards are searched for first -- they will be found
|
|
in EISA slot# order.
|
|
Next, the 3c509 ISA cards are searched -- they are found in increasing
|
|
ethernet address order.
|
|
This is an example of how they will probe:
|
|
.Pp
|
|
ep0 at isa0 port 0x6000-0x600f irq 10: aui/bnc address 00:60:8c:70:e5:c5
|
|
ep1 at isa0 port 0x300-0x30f irq 3: aui/bnc/utp address 00:20:af:10:62:ab
|
|
.Pp
|
|
You may specify the port and irq numbers that the cards are expected
|
|
to be found at, but it is not necessary.
|
|
The cards are sufficiently intelligent to tell us where they
|
|
actually live on the ISA bus.
|
|
.Pp
|
|
.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 0x100.
|
|
Beware!
|
|
Avoid placing other cards at that address!
|
|
.Pp
|
|
Some models of 3c5x9 have all three connectors on them.
|
|
In the case of these cards; you must configure the transceiver type
|
|
with the 3Com supplied DOS configuration disk before the link0/link1
|
|
flags will operate correctly.
|
|
.Pp
|
|
.Sh DIAGNOSTICS
|
|
ep0: reset (status: %x)
|
|
.in +4
|
|
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.
|
|
.in -4
|
|
ep0: eeprom failed to come ready
|
|
.in +4
|
|
The eeprom failed to come ready. This probably means the card is wedged.
|
|
.in -4
|
|
ep0: 3c509 in test mode. Erase pencil mark!
|
|
.in +4
|
|
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).
