[c-nsp] Sup720 password recovery problems

[Sam Stickland]

Hi,

I'm trying to get into a Sup720 for which the password isn't known. In 
fact, I'll be happy just wiping the configuration completely.

Unfortunately dispite doing 'confreg 0x2142' in the rom monitor, when I 
boot it up it, it's reset itself back to 0x2102. It's almost as if the IOS 
is overwritting the register value somehow.

Does anyone have any idea how this might be happening, and how I can get 
into the device?

Thanks,

Sam
