For ethernet to work properly on either a PowerBook 3400 or a PowerBook G3 (not G3 Series), the PowerBook 3400/G3 Modem extension must be installed. The extension is installed on both of these PowerBooks with Mac OS 8.5; do not remove it, even if other modem software is installed. Removing this extension will result in the loss of the ability to use ethernet connections. Note: Macintosh PowerBook G3 computers should not be confused with Macintosh PowerBook G3 Series computers. Though the names are similar, there are significant differences. To visually identify which type of computer you have, close the display and inspect the display case. A Macintosh PowerBook G3 has a small, six-color Apple logo on the display case. A Macintosh PowerBook G3 Series computer has a large Apple logo on the display case that is not six-colored. Unless you are using PowerBook 3400 or PowerBook G3 (but not the G3 Series) you can delete this extension.
