Dear, I have a motherboard Intel Atom 525, Atom D525 processor 1.8 GHz with 4 cores, mikrotik install it without problem, but the problem starts when you get a rb44 (10/100) and it takes me only 1 ethernet port, the same rb44 install it on another PC and works with the 4-port, but when I install Windows 7 on Atom motherboard, the 4 ports are working properly, I hope someone has the solution because I really need the large capacity of the microprocessor to router .
