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.

These cables stay attached to your desktop Macintosh or its SCSI chain.

sWarning: 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. s

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.
