Hi all,
I have a quick question that I hope I can get some help with.
I have 2 systems based on the Intel DH77HC motherboard, both systems works perfectly by themselves.
But when I connect them with a USB unpowered IOGEAR 2 port kvm switch, a "funny" thing happens, but not all the time.
(There are no problems when I use a power USB kvm switch.).
When I power up both systems, one of the systems enter a state where it cannot boot, it starts up and the chassis fan goes to full power, the HDD led and the DVD-Drive activity led blinks like there is some sort of activity, but nothing happens.
The other connected system behaves normally.
This behavior makes me think that the failing system never gets past the initial BIOS boot.
Could it be that the +5V power that comes from the USB connector on one PC goes through the USB kvm switch to the other PC, thus confuses the power supply voltage boot up sequence on the other system?
Interrupting the usual power good, +5VSb initialization of the motherboard and power supply?
Any input would be appreciated.
