I cannot do this in OS X as the Duplexer tool only works in OS 9.1, now in OS X there is a command "ifconfig" which seems to address this problem, but I do not know how to configure this to set my Ethernet port to 10 Mb/s. Can anyone help me, and is this a fairly common problem?
Thank you.

[Editor's note: About the only value I can add here is that there's a file called "iftab" in /etc that needs to be edited. It contains this line:
en0 inet -AUTOMATIC-which needs to be changed to specify the connect rate, I would imagine. Anyone have any info to help configure an Ethernet card manually?]
