The Cat-5 port on the Power[Mac/Book] units does, in fact autodetect the need for an uplink(crossover) connection, and switch to it as a result, thereby eliminating the need for a crossover cable(PITA to find/make) or hub. However, I am not so sure about the extent of the capabilities of any "i" series machines such as the iBook.
Anyone care to shed light on if the iBook can switch to uplink?

As for connecting to the 7200 via the iBook. I just had a brainstorm. A simple way to get the 7200 a valid IP address is to configure its TCP/IP settings for DHCP (Dynamic Host Control Protocol). This is done in Control Panel:TCP/IP.
Create a new configuration, or alter an exsisting one so that the port it uses is "Ethernet" and the configure(?) is set to DHCP.
Once done, turn the machine off.
Then go over to the iBook. Go to System Preferences:Sharing In there turn on Personal file sharing by clicking on the check box. Then hit the button "Internet".
Under "Share your connection from:" select "Airport" (just go with me on this. And int the "To Computers using:" check the box "Built-In Ethernet"
By doing this, you've turned your iBook into a DHCP server to machines plugged into the Ethernet port of your iBook. If you plug your 7200 into that port (hopefully without needing a crossover or hub) and start it up, the 7200 will grab an IP address from it, and you should be good to go with networking.
About that, once the 7200 is started up, make sure it's AppleTalk is active, and you have your HD shared (Can't grab files from a drive that doesn't know it is to be open to the world).
And try to connect - using AppleTalk from the iBook. From the Finder' go to the "Go" menu, and select "Network"
Does your 7200 appear?
If not, try to find the 7200's IP address (can't remember how) - but you can try guessing!
In the iBook, in the Finder, hit cmd-k. Enter the IP address of the 7200 - my guess is that it would be 192.168.2.2 (usually the first address that your iBook's Ethernet card will assign - it keeps 192.168.2.1 for itself). Enter the address like this (without the quotes, of course: "afp://192.168.2.2"
Note: You enter afp for connecting to an Apple machine using AppleTalk (afp stands for Apple File Protocol)
Let us know how this works. (I would say 'keep us posted' but that would be a bad pun wouldn't it? Doh! I said it!)
