[c-nsp] 7206 NVRAM issue

[Joseph Mays]

Got a used 7206 I am trying to bring back to life. It seems to be able to read the PCMCIA card in the slot okay, but after a power cycle it loses config and claims the NVRAM is corrupt, throwing me to rommon. >From there I can tell it to boot from disk0 and it boots alright from the PCMCIA card into the default config. Needless to say, any config I have entered gets lost. Which NVRAM is it referring to? The 4 meg on the motherboard? Is there anyway to clear and reset that, or does it just need to be replaced?
