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?

I had a couple that did that and I was able to fix one of them by 
replacing the battery on the I/O card.
