Appliance Reset Without login?

[#1]

Any option to reset an appliance without CLI login ?

Have a number of old appliances removed and looking for an option to factory reset the data before disposing.  As they are remote across many sites & countries, will be slower if each needs powering on and connecting to a remote console appliance to allow a super-user to login and issue reset all.

Not sure any magic "boot-up and hold three buttons" trick from the LCD panel or secret pin-hole to reset externally :-)

In looking at the NIOS admin guide, any reset of database or everything must be done via the CLI.  Sorry.

What about reset at boot before it loads NIOS?

It would be helpful if there was a way to completely wipe a distantly off-site appliance so it can go into a partner's recycling stream...does the CLI-mode reset actually wipe the database?

Ideally it would be good if we could do a hard wipe of the hard drive.
