Would love to be able to use one of my Matrox cards in my Amiga. Granted, I need to rebuild my Amiga setup still. Gonna see if I can get to it today.
I had some other minor problems, so I reinstalled the Mediator 2.5 update and now it's not causing the reboot.
The problem with that Matrox is that it has a non-transparent PCI to PCI bridge that has to be configured properly or else you can't see through it to the actual Matrox card. All you can see is the Hint Bridge device in PciInfo.
I thought it might be a well documented, common card to write a driver for but it seems to be more trouble than it's worth.
