PS: I tested this in Award Bios........
There seems to be some issue regarding display drivers on some machines if this is used. Just reinstall the drivers, Everything will be fine...........

I have not found any other trouble if the codes are used.

To be on safe side, just back up your data..........

The use of this code is entirely at ur risk........
