ebay. Also have notes for my recent experiences with 3com pcmcia cards (mostly this or that doesn't work). Also look at the strings that are claimed to be supported in the bus specific front ends. Note that the 3C569* are CBUS.

Various models of these cards come with a different assortment of

connectors:

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.

Use the AUI port.

Use the BNC port.

Use the UTP port.

.Pp
|
|
If there are multiple cards in the computer, they are searched for
|
|
in the following order: bus, slot, then ethernet address.
|
|
.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.
|
|
.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).
