Huh?
TOPIC
I have a Macintosh Powerbook 5300 series computer. When I open either the Network or AppleTalk control panel, I only have the choice for LocalTalk Built In. I checked the Extensions folder and all Ethernet components appear to be installed. What am I doing wrong? Why is LocalTalk my only choice? Doesn't this computer work with Ethernet?
DISCUSSION
When a Macintosh PowerBook 190 or 5300 series computer starts up, it checks for the presence of Ethernet hardware driver software. If it does not find hardware driver software which supports Ethernet (in this case, usually an Ethernet PC Card), the only choice available in the network setting control panels is LocalTalk. Of course, if the PC Card is not in the PC Card slot, Alternate Ethernet is a pop-up menu option, but you cannot connect to Ethernet network without first inserting the card.
When the Ethernet card's driver software is installed you can select Ethernet in either the Network or AppleTalk control panel, depending on whether you are using classic networking or Open Transport, respectively.
