It is running PPCBug V1.7 (the AIX version not the NT version)

I have created the Com port boot disk and this is the captured output when the system boots:

Thanks, works a treat.

Sorry, I was trying to be generalistic about my lack of UNIX knowledge, it won't happen again. Looking at the website (www.netbsd.org) I was very impressed by the diverse range of platforms that are supported by the OS, that is why I tried NetBSD as an OS for the PowerStack. I thought if any OS will run on these things, it will be this one.

Thanks,
