I think there is an error in the FAQ for Classic regarding the jumpers on Mediator. It says that with Voodoo 3/5/5 gfx cards the Winzice jumper has to be open. That is not the case - at least not on my Mediator 4000DiMK2 with a Voodoo 5 - 5500, 10MB ethernet and SB128.
When the jumper is open the system resets itself repeatedly during boot. Boots fine with the jumper closed.
Hope this helps others.
