Ahh, so the AGP aperture should not be within the memory space and any other PCI/IO address range. Slowly but surely I become confused. ;-)

I'm afraid I can't answer this question (you know, we have no datasheet for the ArticiaS yet). From what I can see in the log, there is an unassigned memory region (type 0, should be <4GB I guess). Could this affect AGP operation? Gerhard -- Lust, ein paar Euro nebenbei zu verdienen? Ohne Kosten, ohne Risiko!
