I just connected two hard drives to my Mac Plus, and now I can't
boot from one until they are both turned on.  Then the one with
the higher SCSI id boots.  Either one connected individually
will boot, it's just that when both are connected, they both
have to be turned on get the Mac even to recognize their
existences.

Both drives are internally terminated, and my Mac Plus has the
revision two (Lonely Heifer) ROMs, so according to all the
documentation I can find (Tech notes, in particular), all should
be well.  But it isn't, and I don't want to use both drives all the
time (one is old, slow, and noisy).

Thanks for any help you can give me!
