Rethinking that, I assume if an UltraSPARC machine boots from a CDROM drive attached to the built-in ATA controller and the installer later can find the disc to start the installation, it should also work with HDDs on that controller, though maybe not with UDMA speeds, but that was a common issue with some older chipsets IIRC. Not sure if these issues were with disc drives exclusively or also with disk drives.My Ultra 10 has a CMD646 though, which supposedly supports up to UDMA2. Dumb question: Did you check the cabling/jumper settings?
No, not that I remember, it looked like from the factory. But I was also referring to something like [1]. And I also seem to remember similar issues with ALi/ULi chipsets (e.g. used in Blade 100 and 150). [1]: https://ata.wiki.kernel.org/index.php/Pata_cmd64x#Limitations Cheers, Frank
