Ok, the above is the PCI bus. There are 3 root PCI busses on this machines @f0000000, f2000000 and f4000000 (all AGP macs have that, older ones have only one or 2), > 80000000-8007ffff : Apple Computer Inc.

As you can see, they are on the pci bus @f2000000. So for your iomem, you need to pick a range that is covered by this PCI host (that is between 0x80000000 and 0xafffffff and that is not already used by any of the other devices under this PCI host. > a0001000-a0001fff : Apple Computer Inc.

KeyLargo USB > a0002000-a0002fff : usb-ohci Ok, that's the end of devices under [EMAIL PROTECTED] An example of available range here would be 0x81000000 to 0x81ffffff. >b0000000-bfffffff : /[EMAIL PROTECTED] > b0000000-b0003fff : ATI Technologies Inc Rage Mobility M3 AGP 2x > b0000000-b0003fff : aty128fb MMIO > b4000000-b7ffffff : ATI Technologies Inc Rage Mobility M3 AGP 2x > b4000000-b7ffffff : aty128fb FB >f1000000-f1ffffff : /[EMAIL PROTECTED] >f3000000-f3ffffff : /[EMAIL PROTECTED] > f3000000-f33fffff : PCI CardBus #02 >f5000000-f5ffffff : /[EMAIL PROTECTED] > f5000000-f5000fff : Apple Computer Inc.
