Combo Card Problems

I have a 3B1 with 2MB ram on mother board and a 2MB expansion card occupying
one of the system expansion slots.
I also have an Expansion Unit which had 2 dual eia port boards plugged into the
the first two lowest priority slots.
Here's the problem ...
Recently I purchased a "2 Port No RAM" card from Digital Data Systems.
After installing the card in the next empty slot of the Expansion Unit,
I tried setting up the additional ports in the "Hardware Setup/RS232
Expansion Setup" screen. The system still only recognized Ports 1 thru 4.
There was no choice for New Ports 5 and 6.
I tried uninstalling and reinstalling the EIA/RAM Combo Expansion Disk
but still got the same results.
Here are a few questions ...
Can the Expansion bus accomodate three of these cards?
Is there a difference between a dual eia port card versus a
2 port no ram card that I bought ? I do realize that I cannot put
memory boards in the expansion bus, is it possible that even though
there is 0K the board is set up via some jumper to be a
memory board thus causing it to be ignored by my system?
If anyone can help I would really appreciate it.
