[rescue] IPX boot prom image 525-1177 earlier than 04?

[Peter Stokes]

Hi Walter

I guess there is a way of mapping the boot rom into memory space and running a
forth loop to print the contents from the ok prompt on a serial console such
as Putty, then copy/paste the results to give a binary hex output, but no idea
of the mapping or the forth loop required, maybe someone here can help?
