TOPIC

    This article describes the Ethernet Update 1.0. Ethernet Update 1.0 improves the reliability of Ethernet in certain rare network configurations. The update addresses an Ethernet issue where a Macintosh after a period of time that varies by network topology, infrastructure and traffic may continue to transmit but does not receive packets.

DISCUSSION

    Products Affected

    • iMac (Slot Loading) computers manufactured since early November 1999
    • Power Mac G4 computers manufactured since late November 1999
    • PowerBook (FireWire)
    • iBook

    Solution
    It is not necessary to install this update unless you are experiencing reliability issues with your Ethernet networking configuration.

    Ethernet Update 1.0 improves the reliability of Ethernet in certain rare network configurations. These configurations are typically 10 Mbit networks which include coax (10Base5 or 10Base2) network segments in large single collision domains (not separated by switches, for example) that use much smaller than standard interpacket gaps or have carrier collision dropout. This update replaces the Mac OS ROM file with a new version, 3.8.

    The Ethernet Update 1.0 requires Mac OS 9.0.4. Both the Ethernet Update and Mac OS 9.0.4 are available from Apple Software Updates at http://www.apple.com/swupdates/ .
