Hi, busy, busy... Anyway, yes I'm pushing for a TN that talks about all those
narly issues that IM and other documentation do not cover concerning
hard disks, SCSI and partitioning in general (MacOS, A/UX). We did some 
groundwork earlier with a couple of DTS questions (which should be sooner
or later in the DTA library and the Q&A stack. So let's see what will happen.
We have a couple of new DTS engineers that are working with SCSI and similar
issues. Yes, this is an important issue, third party vendors should get whatever
information in order to get their hard disks working with our platforms.
