Is there a way to set up RouterOS to attempt to boot from Network Boot Server for 5 or 15 seconds before timing out and booting like normal? When looking at the Routerboard Settings in Winbox, I see "try-ethernet-once-then-nand" but I want it to behave this way on every boot not just once. I see in COM port access, there is an option of being able to choose "Etherboot (timeout 15s), IDE" which would seem to be the behavior I am looking for but I need to be able to make this setting change without connecting via COM port access.
