Thank you guys.
Unfortunately I was hoping to able to use that information to specify it in the console somewhere. I did not try, but could I have put it the Advanced Options area (when I have a little time I will try it)? I did not think I could specify the src argument there.
I was unable to use it in the windows Ghostcast server. Every time I tried to enter it for the command and click outside of the field it would go back to a single partition.
SO, I had to run the Ghostcast client interactively and manually select the partitions.
I guess I could have created a PXE image with all of the arguments in it.
Luckily I had the box locally and could run it interactively.
Suggestions and comments welcome.
Enhancement : allow the Console and the Ghostcast server interface specify more than one partition!
