[rescue] NVRAM Part sanity check

[Jonathan Chapman]

It can be done on the Sun Blade 100 itself, but requires a complicated/annoying song and dance. I always did it on something else. You can program just the NVRAM section on e.g. a TL866+ programmer, as a 32K NVRAM. It will fail checksum as the clock section throws it off, but will still program the NVRAM part.

Thanks,
Jonathan
