This site is the best place to find jumper information for unfamiliar video cards and motherboards.

Gotta love that site, no end of help.
Still doesn't explain the dip switches though!
I have had (and still have) several of the Trident 8900 cards, and have never had to set a dip switch. While I would like to know also, I would be wary of actually changing them unless the card was non-functional. Holes in the space-time continuum and all that
Modems on the other hand... arg!
Good Luck!

That's because there are no dip switches on that card! There are jumpers and it does explain tham.

Allthough it's for a card based on the TVGA-8800CS (which is the chipset that just preceded the TVGA-8900B), the switch settings should be at least mostly the same.
It seems like most TVGA-8900B-based cards are missing the TTL-output, so most of the switch settings won't really do too much. I don't think the Trident chipset got proper MDA/CGA emulation before the TVGA-8900C chipset, and if you select any other setting than VGA, the card may actually try to display MDA/CGA/EGA at it's native sync rate on the VGA monitor.
