Ethernet w/ OS 9.1?

[COCCORP at aol.com]

Hi; another question, please....

I am forayin' for the 1st time into OS 9.x w/ my new 2400c. I am trying to 
get an Ethernet connection with it established, but in the Appletalk Control 
Panel, I do not even have the option. Just infared and serial...

Also, it is missing in TCP/IP also; not even an option.

What software am I missing? One or two programs (Like "Ethernet?") What 
version?

Thanks...
