The Maple platform can't generate any PCI memory access below 0x8000.0000. So it can't access the VGA buffer. I have removed all these accesses from being generated by the emulator. (all other acceses to the card, including PCI I/O accesses to the VGA registers remain though). I am looking at the radeon driver. Maybe it is confused as it thinks it is running on an OF based machine while at the same time locates a x86 VGA BIOS. -jfs ___________________________________________________________________________ Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !
