The change to AppleTalk v58.1.6 was needed to implement built-in infrared technology (IRTalk). If the version number for AppleTalk had not been revised with the PowerBook 5300 Series computers, then running NSI 1.5.1 would over write the IRTalk changes. So by changing AppleTalk to v58.1.6, even if a user does run NSI 1.5.1, the AppleTalk resources will not be written over because the version pre-installed on the PowerBook is newer than the one on the NSI 1.5.1 disk.
