I have a problem I can't figure out:
I have used old Pentium III PC as a router. It had 5 10/100 M bit Ethernet cards installed - so 5 ports together.

That day came and there were need for extra 8 connections - so I bought 4 x RB44GV 4-port Gbit cards = 16 ports together.

The problem is this: my old PC recognizes only 2 of these cards, but I need all 4 to be installed.

Is there is an tip&trick why my PIII doesn't want to cooperate with all of network cards.
Could there be limitation of ports in Mikrotik 2.9.27 or PIII?

Yes, you have to upgrade to v3.24
