Procurve 2810G: set default boot image?

[RenoNetworkGuy]

Morning, all!  Just updated the Secondary image in a 2810G (J9021A) to N.11.78 (latest available) and am trying to make it the default boot image.  "boot set-default flash secondary" doesn't work; switch doesn't understand "set-default".  "startup-default secondary" doesn't work; switch doesn't understand "startup-default".  Logged in as Manager; same results whether in config mode or not.

Google-Fu is failing me.  Is there another command for this model to set the default boot image?  Just booting off secondary only works until power it removed, then it returns to primary.  Yes, I can copy the secondary image to primary but that defeats the purpose.

Thanks!

To boot the software image stored on Secondary Flash I'm used to perform the boot system flash secondary command (even if default is the image stored on Primary Flash).

Could you share the output of show version, show flash and boot (this one followed by a Tab to see all possible options it could currently accept)?
