I Have an X7DCT main board with an SIMSO+ add-on card. I am using Shared LAN and I am not getting any display on the KVM console. I bough this card so that I can use KVM functionality.
X7DCT has Intel 82573 network controller and it does not support KVM over LAN. To use KVM feature, you will have to use the dedicated LAN cable which came with the card.
