Mini210s no bootloader in NOR

Hi,
I just bought a 210s board, and I wanted to change the OS in the NAND.
When I switch the board to NOR and power on it, nothing happen on the
serial port, the card just beep.

What sould I do ?

I think, there is no NOR memory in Mini210s. This switch is to boot from SD
card. You have to install superboot on SD card using sd-flasher tool and
also copy kernel and root filesystem.

Tomasz you are correct, there isn't a nor chip on the mini210S.

There are some tutorials for the mini210S here:
