Simplifying the SCSI disk connection process
If you regularly plan to use your PowerBook as a SCSI disk
with the same desktop Macintosh, you can leave the cables,
terminators (if any), and the SCSI disk adapter cable attached to
the desktop Macintosh. When you want to use your PowerBook as
a SCSI disk, simply shut down all devices and connect the adapter
cable to the SCSI port on the Duo MiniDock. Make sure to add a
terminator to the end of the SCSI chain when you remove the
PowerBook.
s Warning: Always disconnect your PowerBook from the
adapter cable when you are not using it as a SCSI disk. Your
PowerBook will not work correctly if the adapter cable
remains attached.

Using SCSI disk mode to reinstall system software
If you’re using SCSI disk mode to reinstall system software on
your PowerBook’s hard disk (because its System Folder was
damaged, for example), you may not be able to select a SCSI ID
number for the computer. If you don’t know what the current ID
number is, follow these steps:
1. If there is anything visible on the screen or any other
sign that the computer is on (even if it doesn’t appear
to be working properly), press the power button on the
back of the computer to make sure that all power is off.
2. Connect the PowerBook Duo to the Duo MiniDock.
3. Connect the SCSI disk adapter cable to the SCSI port
on the Duo MiniDock.
Don’t make any other connections yet.
4. Press the power button on the back of the Duo
MiniDock to restart the PowerBook Duo.
