Apple PowerBook Duo Dock (including Duo Dock Plus) - Manual (Page 30)

Installing networking system software
You use the Installer program and the system software disks that came with
your PowerBook Duo (or that you purchased as a separate system software
upgrade kit) to install networking software on your PowerBook.
The following instructions describe how to install the networking software
you need.
1 Insert the PowerBook Duo into the dock.
2 With the PowerBook turned off, insert the first system software disk into the internal
floppy disk drive.
3 Turn on your PowerBook Duo.
The Installer program opens automatically.
4 Click OK.
You see the Easy Install dialog box. (If you have System 7.5, this dialog box
looks slightly different.)
Make sure that the hard disk indicated in the box is the one on which you
want to install networking software. If a different disk appears, click the
Switch Disk button until the correct disk name appears.
Depending on the version of your installation disks, you may see slightly
different information in this dialog box.
