[...] Worth checking, I’ll have look at the drive code and see if I can make sense of it. A follow up question might be does anyone have ATA based install other than the Ultra 5/10 running? Example does anyone have SunFire v100 running debian 9 or 10? I have one that’s offline in a rack (Solaris 10 when it was powered down several years back), I might be able to get my hands on it for testing.
Years ago I had Debian - I believe 5 - running from disk on a Blade 100 using the built-in ATA controller. Later I only ran it diskless with Debian unstable IIRC, same for my V100. 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. Cheers, Frank
