Gigabyte Ga EP-43-DS3R

Hello everybody,
this thread is specifficaly about theGigabyte mainboard EP-43-DS3R.
I'am trying to install mavericks 10.9 via usb stick.The method is unibeast.
My main problem is, that I and other people from my area with the same problem are not able to
install mavericks on boot.The first proplem was that the monitor signal was lost.after that we
can pass these by bootflag: " -v GraphicsEnabler=Yes PCIRootUID=1 npci=0*2000"

So if we go on we can see the first page of the installer where we are
suppoesd to elect the language.Exactly on this screen We CANNOT continue , because
of the mouse and Keyboard! They are just connected via ps2 controller
If anybody can help us, than let us no how to solve these problem.

Thanks Happy

Use a USB mouse and keyboard.

actually i have same problem to get the first language selection page. No matter what i use parameter for boot flag, like GraphicsEnabler=Yes PCIRootUID=1 -v or -x , after 1or 2 minutes, then i will also lost monitor signal.
if someone really can test this and find solution , it's will be appreciated, although it's a little old configuration since 2009.
