Turned off after power return

If at least one of the NAS is not always on (at least when any other is on), then sharing the UPS will be an issue.  Something has to be on to share the info for the others..  The only way around this that I know of is to use an UPS that has a direct Ethernet connection and use SNMP to monitor it.  I think that's available on the old OS4.2.x, but I know it's available on 6.x.

The BIOS update package doesn't change any settings, which are normally in CMOS, not flash memory.  It's just a wrapper around the flashrom utility and the AMI-provided BIOS update source file.

With a VGA header installed, the user does have access to the BIOS on a Pro6, and I don't recall seeing a setting for power condition after power loss and recovery.  The rack mount systems do have it, though.  If there is no setting for it, there is no way to change it.

I'm not sure how the NAS is going to retain the power-on schedule through a power interruption if it doesn't come on at least long enough to re-boot and read the schedule again.  That may be the driving factor for not providing an option.
