What type of Ethernet is standard in the Power Mac G4 models? What Gigabit Ethernet upgrade options are available?
Starting with the appropriately named “Gigabit Ethernet” models, all Power Macintosh G4 models already have Gigabit Ethernet onboard. The earlier “PCI” and “AGP” models only have 10/100Base-T Ethernet onboard but can support faster Ethernet with the installation of a Gigabit Ethernet PCI card. Site sponsor Operator Headgap Systems offers a Gigabit Ethernet card that works in both MacOS 9 and MacOS X and is available for less than US$25 including shipping in the domestic US.
