Debian Squeeze/Wheezy on Ultra 2?

If you wipe the Internal flash you would need to make use of USB Boot Recovery to restore it but the EEPROM data would be lost. Without the EEPROM data RAIDiator x86 4.2.x won't work.

Is there a way to restore the EEPROM data from another (same) model?
I have an Ultra 2 which is 'untouched' (meaning running RAIDiator 4.2.21) and an Ultra 2 which is heavily touched (first tried Readynas OS6 on that one but did not have faith in btrfs, later on ran Debian Wheezy on it).
Somewhere in the process, I think the EEPROM data on the last one got lost, after a OS reinstall and a factore reset I only get the Readynas template on the admin page (so no model is shown). Also in RAIDar no model is shown, but (which seems strange to me) during the factory reset "ReadyNas Ultra 2" was shown.
Re-installing from usb (4.2.24) dit not help...

I'd like to know whether I can extract the EEPROM data from the existing untouched Readynas Ultra 2 to fix the 'Wheezy Ultra 2'. If it can't be done, no problem, I plan on keep running Wheezy on it. But I'm just curious whether it can be done.
Maybe something like dd if=/location/of/eeprom of=/eeprom/backup and vice versa?

Thanks in advance, and a happy and healthy 2014 to all!
