address, TFTP server address and boot image name
See the RouterBOOT section on how to configure loader to boot from network.
Note that you must connect the RouterBOARD you want to boot, and the BOOTP/DHCP and TFTP servers to
the same broadcast domain (i.e., there must not be any routers between them).

Operating System Support

System Architecture

CPU. RouterBOARD 800 series uses the MPC8544 800MHz PPC architecture embedded processor.
Ethernet. RouterBOARD 800 series has two onboard Gigabit Ethernet ports (J12 ETH1 and J13 ETH2)
controlled by the CPU and one additional onboard Gigabit Ethernet port (J1, ETH3) controlled by Atheros
AR8131 Gigabit Ethernet Controller.

MikroTik RouterOS

MikroTik RouterOS, starting from version 4.0, is fully compatible with RouterBOARD 800 series embedded
boards.

RouterBOOT

The RouterBOOT firmware (also referred as boot loader 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 does not fully implement the hardware (RTS/CTS) flow control, so it
is suggested to try to disable hardware flow control in the terminal emulation program in case the serial
console does not work as expected, and if it does not help, make a new cable using the pinout given in the
Appendix.
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:
