Problems using unified drivers with Audigy 1

I went through the process of downloading these "unified drivers" for
Audigy 2 (approx 120 megs) and a patch that's supposed to modify them
so they can be used with Audigy1 and Live. Burned the patched files to
a CD to make an install disc, then ran it. All seemed to be going well
until it asked for a file on the Win98 SE disc. I have first edition.
Does Audigy2 require Win98 2nd edition or is it the drivers? Is there
some way to get around this?

What about the KX project drivers? Will they work with 98 First
edition? Which are better?

Thanks
