Apple Macintosh System 7.5 - Manual (Page 31)

EtherTalk networks
If a network containing Macintosh EtherTalk connections has already been
upgraded to AppleTalk Phase 2, installing System 7.5 will have no effect on
networking.
If the network has not been upgraded to AppleTalk Phase 2, the computers on
which you install System 7.5 will be unable to communicate with the rest of
the network. To ensure compatibility, upgrade to Phase 2 before installing
System 7.5.
Drivers for non-Apple network cards
You must upgrade non-Apple network drivers to AppleTalk Phase 2 on all
Macintosh computers upgrading to System 7.5. Check with the dealer or
manufacturer of your network products for more information.
Upgrading to AppleTalk Phase 2
If you need to upgrade your network or internet to AppleTalk Phase 2, you
should do so before you install System 7.5.
Upgrading to AppleTalk Phase 2 involves
m upgrading network drivers on individual computers
m upgrading internet routers
Upgrading network drivers on System 7 computers
System 7.5 includes AppleTalk Phase 2 software and an AppleTalk Phase 2
driver for LocalTalk. If the Installer detects an EtherTalk or TokenTalk
network card in the computer, it also installs the appropriate driver for this
network type.
IMPORTANT The System 7.5 Installer automatically includes the correct
network driver with the Easy Install option. If you use the Customize option,
be sure you select the appropriate network driver. Even if your computer is
already using an AppleTalk Phase 2 EtherTalk or TokenTalk driver, you must
install a new network driver for system software version 7.5.
