I have purchased new motherboard DQ67SW and updated the BIOS to SWQ6710H.86A.0064 which is released on 26 June 2012.
I am not able to find the option to enable KVM in this BIOS.
KVM access is not located within the system BIOS. Access is thru the MEBx.
MEBx can be accessed by using CTRL+P during boot up.
