Does anyone know how to configure the pxemenu.txt file to generate a submenu? I have more than 9 options that I would like the end users to be able to select from in the preboot services menu.

I've had a google around and although I can see how to do it when using a Netware box as the imaging server, I'm not sure I've seen mention of how to do it when using an OES2 Linux imaging server.

Any pointers would be greatly appreciated.
