OpenGL 1.4 For SiS 650_651_M650_M652_740

I have recently purchased Starwars Knights Of the Old Republic and I am having problems to get the game to work properly. My computer specificataion is as follows:

Processor: Intel® Celeron® CPU 2.00GHz
OS: Windows XP v5.1 build 2600 Service Pack 1
Memory: 512 RAM
Video Card: SiS 650_651_M650_M652_740

The computer was purchased with a P4S533-MX motherboard in the UK. The game is asking for OpenGL1.4 Drivers. Can anyone offer any support.
