RouterBOOT
The RouterBOOT firmware (also referred as Bootloader here) provides the basic functionality to boot an
Operating System. It supports serial console via the onboard serial port at the boot time. The loader supports
booting from the onboard NAND device and from a network server (see the respective section for details on
this protocol).
Boot Loader Configuration
This device doesn’t come fitted with a serial port connector, so all Bootloader specific settings must be done in
RouterOS. See „RouterOS functions”
Boot Loader Upgrading
The boot loader is needed to initialize all the hardware and boot the system up.
The boot loader upgrading is possible from MikroTik RouterOS, from within the “/system routerboard” menu.
Updates are included with each RouterOS update. The procedure is described in the MikroTik RouterOS
manual: http://wiki.mikrotik.com/wiki/Manual:Bootloader_upgrade
RouterOS functions
The default OS of RouterBOARD devices is RouterOS, when the routerboard.npk package is installed, RouterOS
can configure some RouterBOARD hardware settings
