You need to know the maker and EXACT MODEL of your motherboard, not just the chipset it uses. With this information go to the board manufacturer's website and look for BIOS upgrades. Most manufacturers will have a list of board models and the facility to download the appropriate upgrade for that board. They will also have instructions for doing the upgrade, read these carefully and follow them exactly. You must not attempt to use an upgrade which is not meant for your exact model of motherboard. All things are possible except skiing through a revolving door.
