I have not heard any other reports of problems of this type, so I would 
suspect a problem with your machine or NIC.  The possibilities that come 
to mind are:

  - Damaged card: Flash memory chip damaged or encoding circuitry broken.

  - IO Addr. conflict on your machine.  Have you tried removing all other 
cards so there is less possibility of IO Address conflict?  Try doing

     cat /proc/pci

or running a DOS PCI scanner to see what IRQs and addresses are in use.  
this would also explain why PCI IDs are no accessible.  Have you tried 
this card on another machine?  Have you tried programming another card in 
this machine?  Could you have miss-typed the ioaddr for this card 
somehow?  It is saying that it doesn't see a card at that IO Addr.

Those are some ideas that come to mind.  I hope it helps.  Please let us 
know how it goes.

Regards,

Marty
