This gave me pause for thought when I was considering buying a SiS
based motherboard:

Don't try to use ultra-dma on sis chips with revision 0xd0. It loses
immediately with a lost interrupt on udma mode 2, downgrades to mode 1
at which point it silently corrupts data on high disk activity. This
happens on two out of 3 machines I own that exhibit high disk activity.

I didn't buy the board in question, so I've no personal experience.
