After a little searching on the SiS site i found this: http://www.sis.com/support/support_faqs_4.htm
- What should I download the graphic driver for my SiS IGP chipset? UniVGA3? or UniVGA2, UniVGA?
A: Using the following table to illustrate the :
Driver Supporting products
UniVGA3 SiS760, SiS661FX, SiSM661FX, SiSM661MX, SiSM741, SiS741, SiS741GX, SiS651, SiSM650, SiS650GX, SiS650GL, SiS740, SiS650
UniVGA2 SiS651, SiSM650, SiS650GX, SiS650GL, SiS650, SiS740
UniVGA SiS630ST, SiS630ET, SiS630S, SiS630E, SiS630, SiS730S, SiS730SE
If your system chipset is more earlier SiS IGP chipset, like SiS620, SiS530, SiS5598, SiS5596, while entering the SiS download center, please select Graphics Driver > Other SiS series IGP > Your Operating system, then to click â€œGoâ€ will search the driver you need.
It appears yours is a really older chipset so you may have to follow the instructions above. If you do decide to buy a graphics card, which would be the easiest solution, buy nothing less than the Geforce 7-series or make sure the card supports shader model 3.0. That's what a lot of the newer games are using and if you card doesn't support that the game may not run.
