The french link above doesn't appear to be working so I have done an internet search and discovered that the reason for the Mirage 330 driver not being listed is the fact that SiS actually use another driver for it which I discovered on a chinese website.
The link you need to SiS website is :
and go to support, then driver download and then enter OS, IGP cards and select the SIS66x and SIS76x driver which is tried and tested. (The 330 is not listed.)
Took me an hour to discover that so hope this saves you all some time !!
