RouterBOARD 750 Series User's Manual 

 

 

An alternative configuration option is the 

MikroTik Winbox utility

 (Windows only). Winbox can be used to 

connect to the default IP address of 192.168.88.1 with the username 

admin

 and no password. 

In case you wish to boot the device from network, for example to use MikroTik Netinstall, hold the RESET 

button of the device when starting it until the LED light turns off, and the device will start to look for Netinstall 

servers. In case IP connection is not available, Winbox can also be used to connect to the MAC address of the 

device. More information here:  

http://wiki.mikrotik.com/wiki/First_time_startup

 

Onboard NAND Storage Device 

The RouterBOARD may be started from the onboard NAND storage chip. As there is no partition table on the 

de i e, the  oot loader assu es the first  MiB for  a YAFF“ files ste , a d e e utes the file  alled  ker el  

stored in the root directory on that partition. It is possible to partition the rest of the medium by patching the 

kernel source. 

Booting from network 

You can boot the RouterBOARD device from Network with the NETINSTALL software, if your RouterOS 

software needs to be reinstalled or reset. Hold the Reset button, power on the device, and release until the 

LED light stops flashing. See 

Buttons and Jumpers  below for details. The Netinstall program can be 

downloaded from 

www.mikrotik.com

 download section.  

Network boot works similarly to PXE or EtherBoot protocol, and allows you to the device from an executable 

image stored on a TFTP server. It uses BOOTP or DHCP (configurable in boot loader) protocol to get a valid IP 

address, and TFTP protocol to download an executable (ELF) kernel image combined with the initial RAM disk 

(inserted as an ELF section) to boot from (the TFTP server's IP address and the image name must be sent by the 

BOOTP/DHCP server). 

To boot the RouterBOARD computer from Ethernet network you need the following: 

 

An ELF kernel image for the loader to boot from (you can embed the kernel parameters and initrd image 

as ELF sections called kernparm and initrd respectively) 

 

A TFTP server which to download the image from 

 

A BOOTP/DHCP server (may be installed on the same machine as the TFTP server) to give an IP address, 

TFTP server address and boot image name 

Operating System Support 

MikroTik RouterOS starting from version v5 is fully  compatible with the device. If your device is preinstalled 

with an earlier RouterOS release, please upgrade RouterOS to v5.8 or newer. 

Buttons and Jumpers 

 

RouterOS reset jumper hole (on the 

bottom

 of case) 

 resets RouterOS software to defaults. Must 

short circuit the metallic sides of the hole with a screwdriver and boot the device. Hold screwdriver in 

place until RouterOS configuration is cleared.   

 

RouterBOOT reset button (

RES

, front panel) has two functions:   

o

 

Hold this button during boot time until LED light starts flashing, release the button to reset 

RouterOS configuration (same result as with RouterOS reset hole)
