[nsp] Recoving from a bodged 6500 IOS conversion

[Robert A. Hayden]

I think, if I remember last time I botched an IOS -> Hybrid conversion,
that there's an undocumented command you can run from the MSFC rommon mode
that is something like

download sup-bootflash:<filename>  bootflash:

That will allow you to get an image into the Sup's booflash from the flash
card and then over to the MSFC's booflash and go from there, but it's been
several months and my memory is rather horrid this week.
