How do you go about adjusting it?

GO LOOK AT IT! im going to assume with normal hand tools, i think it works in the same way a wastegate does on a turbo, so that would be the first thing to do is go look at it, and figure out what you're workin with.

You assume too much.

bingo

I'm going to check my plugs when I get home, make sure they're the correct heat range and gap.

Apparently the boost mod I was talking about (the link of which I just noticed is broken, I'll fix it when I get home), will bypass this whole thing, but it's not necessarily a good idea either if your engine really is knocking. So I'll try and fix the source of the problem first.
