locked out of os

I have managed to lock myself out of my os. It is installed on a wrap2dx board. Is there a way to reset the board so I can get back into it? Unable to discover MAC address with winbox loader.
Thanks

Take out the drive and use the NetInstall application provided in the download section to re-image it.

the wrap board uses a onboard memory chip

Does it have a usable console port? Interrupt the boot process and set it to PXE boot, use NetInstall to re-image the storage from the network.

other than lan port and serial port (of which none of my computers have), that is all. it is a board install in a weather proof box for outside installation.
