Manual:RouterBOARD settings

General

Sub-menu level: /system resource

On RouterBOARD devices, the following menu exists which gives you some basic information about your device:

[admin@demo.mt.lv] /system routerboard> print 
       routerboard: yes
             model: 433
     serial-number: 185C01FCA958 
  current-firmware: 3.25
  upgrade-firmware: 3.25

Properties

All properties are read-only

Property	Description
model (string)	If this device is a MikroTik RouterBOARD, this describes the model name
serial-number (string)	Serial number of this particular device
current-firmware (string)	The version of the RouterBOOT loader that is currently in use. Not to be confused with RouterOS operating system version
upgrade-firmware (string)	RouterOS upgrades also include new RouterBOOT version files, but they have to be applied manually. This line shows if a new RouterBOOT file has been found in the device. The file can either be included via a recent RouterOS upgrade, or a FWF file which has been manually uploaded to the router. In either case, the newest found version will be shown here

Upgrading RouterBOOT

RouterBOOT upgrades usually include minor improvements to overall RouterBOARD operation. It is recommended to keep this version upgraded. If you see that upgrade-firmware value is bigger than current-firmware, you simply need to perform the upgrade command, accept it with y and then reboot with /system reboot

 [admin@mikrotik] /system routerboard> upgrade 
 Do you really want to upgrade firmware? [y/n] 
 y
 echo: system,info,critical Firmware upgraded successfully, please reboot for changes to take effect!

After rebooting, the current-firmware value should become identical with upgrade-firmware

Settings

Sub-menu level: /system routerboard settings

[admin@demo.mt.lv] /system routerboard settings> print 
           baud-rate: 115200
          boot-delay: 2s
      enter-setup-on: any-key
         boot-device: nand-if-fail-then-ethernet
       cpu-frequency: 1200MHz
    memory-frequency: 1066DDR
       boot-protocol: bootp
 enable-jumper-reset: yes
 force-backup-booter: no
         silent-boot: no

Property	Description
baud-rate (integer; Default: 115200)	Choose the onboard RS232 speed in bits per second (if installed)
boot-delay (time; Default: 1s)	How much time to wait for a key stroke while booting
boot-device (nand-if-fail-then-ethernet ...; Default: nand-if-fail-then-ethernet)	Choose the way RouterBOOT loads the operating system: flash-boot - flash-boot-once-then-nand - nand-if-fail-then-ethernet - nand-only - try-ethernet-once-then-nand -
boot-protocol (bootp |dhcp ...; Default: bootp)	Boot protocol to use: bootp - the default option for booting RouterOS dhpc - used for OpenWRT and possibly other OS
cpu-frequency (depends on model; Default: depends on model)	This option allows for changing the CPU frequency of the device. Values depend on model, to see available options, hit [?] button on the keyboard at this prompt
cpu-mode (power-save | regular; Default: power-save)	Whether to enter CPU suspend mode in HTL instruction. Most OSs use HLT instruction during CPU idle cycle. When CPU is in suspend mode, it consumes less power, but in low-temperature conditions it is recommended to choose regular mode, so that overall system temperature would be higher
enable-jumper-reset (yes | no; Default: yes)	Disable this to avoid accidental setting reset via the onboard jumper
enter-setup-on (any-key | delete-key; Default: any-key)	Which key will cause the BIOS to enter configuration mode during boot delay. Note that in some serial terminal programs, it is impossible to use Delete key to enter the setup - in this case it might be possible to do this with the Backspace key
force-backup-booter (yes | no; Default: no)	If to use the backup RouterBOOT. This is only useful if the main loader has become corrupted somehow and cannot be fixed. So that you don't have to boot the device with a pushed reset button (which loads backup loader), you can use this setting to load it every time yes - backup loader will be used always no - main booter will be used
memory-frequency (depends on model; Default: depends on model)	This option allows to change the memory frequency of the device. Values depend on model, to see available options, hit [?] button on the keyboard at this prompt
regulatory-domain-ce (yes | no; Default: )
silent-boot (yes | no; Default: no)	This option disables output on the serial console and beeping sounds during booting, to avoid the text output interrupting a connected device. Useful if you have some temperature monitor or modem connected to the serial port yes - no output on the serial console and no booting beeps (does not disable the RouterOS :beep command) no - regular info and option menu on serial console

Protected bootloader

This is a new feature which allows the protection of RouterOS configuration and files from a physical attacker by disabling etherboot. It is called "Protected RouterBOOT". This feature can be enabled and disabled only from within RouterOS after login, i.e., there is no RouterBOOT setting to enable/disable this feature. These extra options appear only under certain conditions. When this setting is enabled - both the reset button and the reset pin-hole is disabled. Console access is also disabled. The only ability to change boot mode or RouterBOOT settings is through RouterOS. If you do not know the RouterOS password - only a complete format is possible.

• The backup RouterBOOT version can not be older than v3.24 version. A special package is provided to upgrade the backup RouterBOOT (DANGEROUS). Newer devices will have this new backup loader already installed at the factory. Download the package for mipsbe platform here, smips platform here or for tile platform here.
• RouterOS version 6.33 or later is required to enable this feature

Property	Description
protected-routerboot (enabled | disabled; Default: disabled)	This setting disables any access to the RouterBOOT configuration settings over a console cable and disables operation of the reset button to change the boot mode (Netinstall will be disabled). Access to RouterOS will only be possible with a known RouterOS admin password. Unsetting of this option is only possible from RouterOS. If you forget the RouterOS password, the only option is to perform a complete reformat of both NAND and RAM with the following method, but you have to know the reset button hold time in seconds. enabled - secure mode, only RouterOS can be accessed with a RouterOS admin password. Any user input from serial port is ignored. Etherboot is not available, RouterBOOT setting change is not possible. disabled - regular operation, RouterBOOT settings available with serial console and reset button can be used to launch Netinstall
reformat-hold-button (5s .. 300s; Default: 20s)	As an emergency recovery option, it is possible to reset everything by pressing the button at power-on for longer than reformat-hold-button time. Even if reformat-hold-button time is forgotten, holding the reset button for more than 300s will allow you to perform reformat. When you use the button for a complete reset, following actions are taken: EXTREMELY DANGEROUS. Use this only if you have lost all access to the device. RouterOS, all of its files and configuration is completely and irreversibly erased by nand re-format; all RouterBOOT settings are reset to defaults; Board is rebooted; As boot from NAND fails, it goes to etherboot automatically; Netinstall is required to reinstall RouterOS. Please note that after complete reformat, on some Routerboards it can take a few minutes until the device will appear in Netinstall window.
reformat-hold-button-max (5s .. 600s; Default: 10m)	Increase the security even further by setting the max hold time, this means that you must release the reset button within a specified time interval. If you set t he "reformat-hold-button" to 60s and "reformat-hold-button-max" to 65s, it will mean that you must hold the button 60 to 65 seconds, not less and not more, making guesses impossible. Introduced in RouterBOOT 3.38.3
