Does anyone know exactly how the 'Startup Device' cdev works?  I've looked
in the System 6 documentation, and it doesn't say very much.  My problem is
this:  The hard disk I designate as the startup device is NOT the device
that boots when the machine is turned on, but it IS the device that boots
when I do a 'Restart'.  I have a MacII with 2 40MB hard disks.  The disk
at SCSI ID 0 is the original Apple Quantum 40.  The disk at SCSI ID 1 is
a Connor CP340 40MB 3.5" disk.  Both disks have System folders with the Mac
icon on them.  (I thought this meant they were blessed, but I'm not sure.)
On both Systems, I have the startup device set to the Conner drive (it's
faster and quieter).  I am currently using System 6.0.3.  What do I need
to do to make the Conner drive boot when the machine is first turned on?
Is it something in the PRAM?  Does the machine always use the drive at ID 0?
Do I have the terminators on the wrong drive?  Is anything I've said even
relevant?

Any help will be appreciated.

Thanks in advance,
