I can't find the option to enable KVM i configuration: DQ77KB + i5-3450S. After many hours of googling I got into configuration in Bios (Intel Management Engine BIOS Extension) ME v220.127.116.114 but there is no option to enable KVM. Did I something wrong or this configuration (DQ77KB + i5-3450S) doesnt support KVM?
The KVM is part of AMT and the DQ77KB motherboard is AMT enabled, however your i5-3450S is not AMT enabled. You need both components to be AMT enabled for AMT to work. Most i5 processors are AMT enabled, but not in this instance.
