Curious.  I missed the first part of this thread, but it looks suspiciously
like the behavior of my 1542B/ Seagate 296N combination under Xenix 2.3.2.
On the initial power-up sequencing, the Adaptec will poll for devices
before the Seagate has finished it's recalibration. After about ten seconds
of silence, the ST296N will restart what sounds like it's power-on self
test, and the 1542B will then report it as Drive C and continue.

Come to think of it, this is not OS specific, because it does this when I
run it under DOS as well.
