35.Sh NAME
36.Nm ep
37.Nd Ethernet driver for 3Com Etherlink III (3c5x9)
38.Sh SYNOPSIS
39.Cd "device ep"
40.Sh DESCRIPTION
41The
42.Nm
e842db4d 43device driver supports the 3c509 (ISA), 3c529 (MCA),
984263bc
MD
44and various PCMCIA cards including the 3c589.
45Various models of these cards come with a different assortment of
46connectors:
984263bc
MD
47.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
48.It AUI/DIX
49Standard 15 pin connector, also known as 10base5 (thick-net)
50.It 10Base2
51BNC, also known as thin-net
52.It 10BaseT
53UTP, also known as twisted pair
54.El
55.Pp
56The default port to use is the port that has been selected with the
57setup utility.
58To override this, use the following media options with
59.Xr ifconfig 8
60or in your
61.Pa /etc/rc.conf
62file.
984263bc
MD
63.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
64.It 10base5/AUI
65Use the AUI port.
66.It 10base2/BNC
67Use the BNC port.
68.It 10baseT/UTP
69Use the UTP port.
70.El
71.Pp
72If there are multiple cards in the computer, they are searched for
73in the following order: bus, slot, then ethernet address.
74.Sh NOTES
75The 3c509 card has no jumpers to set the address.
763Com supplies software to set the address of the card in software.
77To find the card on the ISA bus, the kernel performs a complex
78scan operation at IO address 0x110.
79Beware!
80Avoid placing other cards at that address!
984263bc
MD
81.Sh DIAGNOSTICS
82.Bl -diag
83.It ep0: reset (status: %x)
84The driver has encountered a FIFO underrun or overrun.
85The driver will reset the card and the packet will be lost.
86This is not fatal.
87.It ep0: eeprom failed to come ready
88The eeprom failed to come ready.
89This probably means the card is wedged.
90.It ep0: 3c509 in test mode. Erase pencil mark!
91This means that someone has scribbled with pencil
92in the test area on the card.
93Erase the pencil mark and reboot.
94(This is not a joke).
