Very Computer

I use an EtherExpress PRO 10+/ISA LAN adapter for my FreeBSD 2.2.6.
This adapter has three connectors: TPE, AUI and BNC.  I use the BNC
to connect to my network backbone.  For each time the system reboot,
this interface (ex0) has unexpected condiction, work properly or
cannot ping out.  I do some cross tests with FreeBSD, Win95, LAN cards
and PCs.  The network cable and connectors are ok, LAN card is no
problem (softset2 test ok, work properly on Win95), ifconfig -a seems
ok.  Then strang message from ex0 by check dmesg:

ex0 at 0x210-0x21f irq 5 on isa   ;this line is ok
ex0: Intel EtherExpress Pro/10+, address ..., connector TPE

the second line has wrong connector detection.  The connector appeared
is AUI or TPE, but never BNC in here.  What happen with ex0? How can I
fix this problem?

;====
tmp = inb(iobase + REG3);
if (tmp & TPE_bit)
        sc->connector = Conn_TPE;
else if (tmp & BNC_bit)
        sc->connector = Conn_BNC;
else
        sc->connector = Conn_AUI;
;====

I think...maybe the system(PC, Pentium-133) is too fast to get or
peripheral(LAN Card) is too slow to respond for IO input inb() to
cause the wrong value for var "tmp".  Any ideal for this condiction is
appreciated.

Looking though the code, I don't see anything that's selecting which
connector to use.  So this means the card for some reason has the wrong
idea about what connector to use on it's own. (or if there's a way to
tell the card which connector to use, the driver doesn't do it).

Does the card come with some type of DOS config/setup utility?  Maybe
you have to run that to tell it to use the BNC interface?  Or are their
jumpers on the card that need to be set?  Did you get that same card
in the same system to work under another OS?  Did you try to use the TPE
interface on that card under FreeBSD?  If you can use the TPE interface
but not the BNC on FreeBSD, but both works on Win95, then it sounds like
a driver problem.
