Sounds like a matter of RTFM. Check the multimedia CD, there are docs in each directory. Check also those directories, you don't have hardware for. For example the Voodoo4&Voodoo5 dir contains important hints for the Voodoo installation in general.
Basically you have to install Picasso96 youself, choosing a Cybervision64 (IIRC) as graphics card. Then go to devs/dosdrivers and rename the CVision driver to Voodoo. Finally change the tooltypes of the driver to point to Voodoo.card instead of CVision.card or so. But don't rely on this, better read the docs yourself.
