integrated graphics chip on Foxconn P4M800
 

I recently put together my first desktop (the first one I made myself), however, in order to configure Xorg properly, I need to know how much graphical memory my motherboards onboard graphics chip has...there is nothing on the box I bought it in to give me a clue, and neither is there anything about it on the website I got from, or the manufacturers website (only "integrated graphics"). ANy help at all?

I'm installing slackware, and only have to get my xorg config done properly for it to work now.

any help is muchly appreciated.

Oh, and by the way, my chipset is SiS661FX+964
