Upgrading network drivers on System 6 computers

To upgrade EtherTalk drivers on Macintosh computers that are not being

upgraded to System 7.5, use the EtherTalk software (version 2.0 or later) and

instructions furnished with the EtherTalk NB Card or the Ethernet LC Card.

Internet routers

A Macintosh computer used as a router does not need to be upgraded to

System 7.5 to work with System 7.5 computers on the network.

Hardware-based routers that support AppleTalk Phase 2 are also compatible

with System 7.5.

If a Macintosh is being used exclusively as a router, no benefit is derived from

upgrading this Macintosh to System 7.5.

Determining whether a router supports AppleTalk Phase 2

The Apple Internet Router 3.0 (or later) from Apple Computer supports

AppleTalk Phase 2 only. (The earlier AppleTalk Internet Router 2.0 is no

longer recommended.)

For non-Apple routers, check the product documentation or contact the

router’s manufacturer or the dealer.

Software or hardware upgrades for routers

The process of upgrading a router to AppleTalk Phase 2 depends on the type

of router and its manufacturer.

The Apple Internet Router 3.0 assumes that your network is already Phase 2.

Refer to the documentation for the router for additional information.

All major vendors of internet routers for AppleTalk networks offer AppleTalk

Phase 2 upgrades for their Phase 1 routers. Contact the dealer or

manufacturer of your routers about upgrades.
