OK!Since it's not really documented anywhere that I can see, here's what I've ascertained from the STB PowerGraph C33's JP2/1-3 settings:
JP2/1: Waitstate jumper 0?
JP2/2: Waitstate jumper 1?
JP2/3: Sync rate? (when set, it uses regular VGA sync rates, but when removed, it outputs at different frequencies - crappy monitors and flatpanels beware!)

Sorry to bump this old thread, but I just got a PowerGraph C33 and I was wondering about these jumpers. Does setting JP2/1 and JP2/2 enable the zero waitstate mode which speeds up the card? I see a lot of references to it but I can't find any documentation on it. Is there any downside of doing this?

Also, did you update the BIOS on this card? Mine says 1.0 but I know there's at least a 1.2 or 1.3 out there.

I unfortunately no longer have this card, I sold it years ago. I wish I could answer your questions 🙁
