System 7 automatically installs and supports AppleTalk Phase 2 networking
software. If your network consists entirely of LocalTalk, PhoneNet, or
TokenTalk (or some combination thereof), this has absolutely no impact on
you and you don't need to read any further. Phase 2 software only affects
networks that have EtherTalk.
But a Phase 1 EtherTalk driver that works with System 7 is available on the CD
that comes as part of the System 7 Group Upgrade Kit. The procedure and
software for installing Phase 1 under System 7 are contained on the CD, or
on AppleLink.
The reason for this approach is that Apple is migrating the installed base
to AppleTalk Phase 2. We want all new System 7 users to automatically have
Phase 2 software on their Macintosh computers. However, some people will be
installing System 7 on their existing Phase 1 networks, and they will need
the Phase 1 EtherTalk driver until they have completed their migration to
Phase 2.
The datalink software (EtherTalk and TokenTalk) included and installed with
System 7 is Phase 2. However, a network of mixed Phase 1 and Phase 2
drivers can be implemented, provided the network administrator has set up
the internet routers with the appropriate migration utility. Migration
issues will affect only those networks using EtherTalk datalink software,
because no version of TokenTalk predates version 2.0.
Network applications (like AppleShare File Server and Print Server
software), system software, and its associated services are Phase
independent. They can connect to and use services on any AppleTalk
network.
The following is the Read Me file that is found on the Group Upgrade Kit
CD:
EtherTalk Phase 1
-----------------
EtherTalk¿ software allows communication with AppleTalk¿ network services
over Ethernet networking interface cards and media. EtherTalk Phase 2
software is part of Macintosh¿ system software version 7.0. This folder
contains an earlier version of EtherTalk software, EtherTalk Phase 1.
You only need to install EtherTalk Phase 1 software for users who have
Ethernet networking interface hardware and who are connected to a network
that has not been upgraded to support AppleTalk Phase 2. AppleTalk Phase 2
transition and upgrade are discussed in the "System 7 Group Upgrade Guide."
To install the EtherTalk Phase 1 software, begin by installing the
EtherTalk software as part of the System 7 installation procedure. Next,
drag the EtherTalk icon to the icon of your System Folder (not the open
System Folder window). It is automatically placed in the Extensions folder
inside the System Folder.
To select the EtherTalk Phase 1 software, open the Control Panels folder,
located in the System Folder. Double-click the Network control panel.
Finally, select the EtherTalk icon.
