IS bios affect on the graphic card upgrade


in pci express x16 slot a loose plastic handle is given what is the use of plastic handle.
 
That plastic handle hold the card from falling or being loose. When you place i the card you will see a curved shape near the chips which go into Pci-e slot, the loose plastic handle get stuck at curved shape to prevent loosing. When you want to remove push it a little back and then remove the card.
 

and mine chipset is sis672 it can support gtx650 ddr5 graphics card.
 
but there no update for this chipset
