I have a 3C503-16 ethernet card in a 486-50 running Linux 2.0.27. The networking works fine, but slow, when I jumper the card to disable shared memory. However, if I enable shared memory, I get a stream of Bogus Packet error messages. It does not matter what the shared memory address is.
I do not believe there are any conflicts in the computer. Any ideas about how to be able to use Shared Memory on the ethernet card?
