RouterBOOT is responsible for starting RouterOS in RouterBOARD devices.
Main and Backup loaders
By default, the main (regular) loader is used, but RouterBOARD devices also have a secondary (backup) bootloader, which can be used in case the main doesn't work. It is possible to call the backup loader with a configuration setting in RouterOS:
...
- Hold this button during boot time until the LED light starts flashing, and release the button to reset the RouterOS configuration (total 5 seconds)
- Keep holding for 5 more seconds, LED turns solid, release now to turn on CAPs mode (total 10 seconds)
- Or Keep holding the button for 5 more seconds until the LED turns off, then release it to make the RouterBOARD look for Netinstall servers

RouterBOARD serial port is configured to 115200bit/s, 8 data bits, 1 stop bit, and no parity. We suggest disabling the hardware flow control.
