Ok, there are a bunch of questions to which you must know the answer in 
order to debug a remote target: 

What's the communications protocol?
This is the actual hardware communications between the host (running 
gdb/insight) and the target. Is it a serial connection? Ethernet? JTAG? 
For serial, you'll need to know what serial port the target is attached to 
and the baud rate. For ethernet, you'll need a hostname/IP address and 
port number. If you're using a JTAG box, you'll obviously need to know 
these parameters for the interface, not for the board proper, since GDB 
will be talking to the JTAG interface.

What's the debug protocol?
This could be the tougher one. GDB understands how to talk a bunch of 
different debug protocols, its own "remote" protocol, many monitors, a 
couple of JTAG, etc.

On this one, I don't know how to help you out. You're going to have to 
find out what the board uses (if anything). Maybe you'll need to get a GDB 
debug stub/agent on the board? I don't know. You might ask on 
gdb@sources.redhat.com about your particular hardware if web searches 
don't turn anything up.

Anyway, once you have this information, you can use the File->Target 
Settings... dialog to specify these things.
