@Allan

So you had the mediator bridge installed in the Elbox ZIII board when MOS worked?

I had MOS running perfectly with my mediator and using a CV PPC for graphics stuffed in my CS PPC but I never could use any of my ZII network cards because MOS couldn't recognize them....I think the Elboz ZIII board is wired differently
My Mediator bridge was jumpered 256meg as I was using a Voodoo 3000

Never start working in the marine business, this time of year it consumes your life :o
