AFAIK running one card in half-duplex mode and the other trying to force full-duplex mode can lead to lots of collisions, so this could be a reason for slow speed. you could use a hub or switch instead of the crossover cable and watch the collision LED (if there is any *g*). greetings, ulric -- ulrich schwarz, computing center, university of ulm, germany
