Hello

is it possibile to use both a Voodoo 3 and a Radeon 9250 GFX card on Amiga4000 with AmigaOS 4.1FE?
when i install the OS it only recognizes the Voodoo 3 and when i boot up the Amiga after installation there is no way to add or find the Radeon, what's wrong? I'd like to use the Radeon 9250 on the OS4.1 side while i use the Voodoo3 on AmigaOS 3.2 partition so i want to keep both in the tower.
Any suggestion is welcome

Same here, i also would like to use the radeon för os4 and voodoo för classic os.
I think i even started a thread about it many years ago.

Anyway the answer i found was "no"
It does not even help to disable the voodoo driver in the kicklayout.

The only working solution i found was someone who had installed som kind of HW switch to disable the voodoo.
But i have no idea how to build that switch.

To usage Radeon under AOS 4.1 with Voodoo card in PCi slot (Mediator), you can lock pin A26 (Init Device Select).
