These timestamps are the ones of the rom files; the actual boot time would be
30-60 seconds earlier.

The boot at 2007-03-05 10:17 was a cold boot.

The boot at 2007-03-05 11:00 was a cold boot.

The boot at 2007-03-05 13:01 was a *really* cold boot: I unplugged power,
waited 10 seconds, and then replugged and started the machine.

All other boots were warm boots.

Thanks,
Ward.
