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?
