EEProm dump of Aruba AP-303 flashed with OpenWrt


I would like to dump the complete EEProm content into a file to flash it directly onto another eeprom (by a hardware flasher) of this device:

So Bootloader et all should be also included.

How do I do this correctly? Simply cat /dev/mtdX > /tmp/whatever.img or do I have to do something else to have a complete writable Image?

Thanks a lot!
