I have a 3dfx Banshee card 16MB AGP.  It is disguised as an Ensoniq card.  

I have tried to install your x-mojomotion driver in Win98, but am told that the program cannot be setup due to being an invalid install package.  I execusted the included windows installer file and got the same results.  The same thing happens when I try to launch the tools file by itself.  Any help?
