Run the 3c5x9cfg utility, turn OFF the plug-n-play on the cards.  Set 
the adaptor media to what you need ie (BNC,TP, etc.).
This worked for me....The cards are actually 3c509C's, the configure 
utilitie detects them as B's.  I've got 2 of them in along with a 
regular 3c509 working fine.  (after the pnp was turned off and media 
set....I suspect the pnp though).
