Inside the disk image ( did you get it and unzip it ?) you wil find FULL instruc inside the ssh folder on the image ( assuming you have mounted the dmg first

)
First you must unzip/clone to usb stick ( I use a plain-jane 512Mb Kennsington USB thumb drive or stick) and then insert the right files into the ssh folder and you should be gold. As I said there are full instrucs.
I tried to make this as painless as possible.
I'm sure you can find someone nearby with a an Intel mac running Tiger that can help you.
