Right. I missed the "with some utility" part of the Configure.help, but
got the "data that is not lost at power-off" part. Thus I was under the
impression that the memory could be used for non-volatile storage.

Yes, yes.

Difference is, these have IMHO more meaningful names and more obvious
uses. I'd *expect* throwing garbage at /dev/bios to muck up the bios
settings.

Yep, I had to pull the jumper to clear the password, boot into BIOS, set
things up and reboot. No sweat, just unexpected.

I promise not to do it again. Thanks to all that pointed out the error
of my ways.
