Operating System Support

MikroTik RouterOS

MikroTik RouterOS, starting from version 3.0rc1, is fully compatible with RouterBOARD 1000 series
embedded boards.

RouterBOOT

The RouterBOOT firmware (also referred as Bootloader here) provides minimal 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

Loader parameters may be configured through the onboard RS232C DB9 asynchronous serial interface. To
connect to it, use a standard null-modem cable. By default, the port is set to 115200bit/s, 8 data bits, 1
stop bit, no parity. Note that the device also implements the hardware (RTS/CTS) flow control.
To enter the loader configuration screen, press any key (or only [Delete] key (or [Backspace] key – see the
note for the respective configurable option), depending on the actual configuration) just after the boot
loader is asking for it:
RouterBOOT booter 2.11
RouterBoard 1000
CPU frequency: 1333 MHz
Memory size: 512 MB
Press any key within 2 seconds to enter setup
RouterBOOT-2.11
What do you want to configure?
d - boot delay
k - boot key
s - serial console
o - boot device
r - reset configuration
e - format nand
g - upgrade firmware
i - board info
p - boot protocol
t - do memory testing
x - exit setup
your choice:
To select a menu point, press the key written at the beginning of this line. Pressing [Enter] selects the
option marked with '*'.

Configurable Options

boot delay – how much time to wait for a key stroke while booting (1..9 seconds; 2 second by default).
boot key – which key will cause the loader to enter configuration mode during boot delay (any key |
<Delete> key only; any key by default). Note that in some serial terminal programs, it is impossible to use
the [Delete] key to enter the setup – in this case it might be possible to do this with the [Backspace] key.
serial console – to configure initial serial console bitrate (1200 | 2400 | 4800 | 9600 | 19200 | 38400 |
57600 | 115200; 115200 bps by default).
boot device – initial boot device (boot over Ethernet | boot from NAND, if fail then Ethernet | boot from
CompactFlash only | boot Ethernet once, then NAND | boot Ethernet first, then CompactFlash | boot from
NAND only; boot from NAND, if fail then Ethernet by default). You can also select boot chosen device
option to boot from the device selected immediately, without saving the setting.
reset configuration – whether to reset all the boot loader settings to their respective default values (yes |
no; no by default).
