Install the drivers available on the disk to program them

The mouse is a Microsoft PS/2 mouse.And the drivers for the mouse are the latest.But there is no option to actually configure the 2 circular buttons present above and below the wheel.Please Help.

Man, search the disk u have to find some s/w on the disk to use them. As these two buttons are programmable and u need a s/w for that
