TOPIC


    I have several different Ethernet PC cards that I need to use. I seem to have trouble getting on the network when I switch cards. Why?

DISCUSSION


    When switching between PC Cards on a Macintosh PowerBook 5300 Series computer, you must pay careful attention to any software drivers that get left behind that are no longer going to be used. The Ethernet drivers are particularly susceptible to "confusion" if not removed.

    As an example of this, if you have a Dayna Ethernet card and switch to a PowerPort Platinum Pro PC Card, you will experience problems with Ethernet if you fail to remove the Dayna drivers. This is because the MacOS only recognizes two different Ethernet driver names, and Global Village and Dayna (in this case) have chosen the same name (Ethernet Driver). The symptom will be that Ethernet will work intermittently, if at all.

    Be sure to get all the parts of the old driver software (use the Installer to remove/de-install the driver software, if possible) when removing it. In particular, be sure to remove the Ethernet driver from the System suitcase.
