I do have a question concerning the ethernet card DEC 21040 of my Alpha
200 4/100.

(cavet: maybe ethernet is already running, but I can't tell because the
ethernetcard on the other side of the network (intel-linux) is also
making trouble. nothing sent at one side reaches the other side. sniffit
keeps silent).

My ethernetcard has two interfaces, 10 Base-T and 10 Base 2 (BNC). To
avoid buying a hub I would like to use the latter interface.

the manpage for "de" tells me that I do have a 10 Base-T and an AUI/BNC
interface. what do the manpage mean with AUI/BNC? I don't have an AUI
but just a BNC interface! anyway.

when using ifconfig's media option I get besides the argument "10baseT"
also the argument "AUI" but not the argument "BNC" working (SIOCGIFFLAGS
inet: Device not configured).

the main question: what argument do I need for ifconfig's media type?
AUI although I would like to use BNC?

The Alpha 500 manual (not 200) which explains me that I have to set for
some, but not for all, OSes the environment variable ewa0_mode at the
>>>-prompt to some value. do I have to fiddle around with that, too?

I would appreciate any help.

thanks, Stefan
