I'm not sure what the correct fix for this is but I wanted to set the record straight. The PowerMac11,2 is supported but does have some DMA issues with the SATA controller that can result in timeouts. All OpenBSD/macppc machines are 32-bit or run in 32-bit mode like the PowerMac G5. I believe that is why there are issues with large amounts of memory. I have a PowerMac11,2 that has more than 8GB of memory (I can't remember the exact amount) and it only uses 2GB as well under OpenBSD. I also ran into some radeon(4) issues which I documented in some older threads. I have not had time to get back to working on anything further with my PowerMac G5 units but the model you have should work reasonably well except for possible SATA issues. Bryan
