Reading the EEPROM settings in Marlin

Hi

I have Marlin firmware and have read the M commands on the wiki on this page - [reprap.org]. I use Repetier host software to print

There are only M [500, 501, 502] commands to store settings into EEPROM and to read settings from EEPROM into the printer.

Is there any way of finding out what exactly the current EEPORM settings are?

What I would like to do is issue a command in Repetier that will read my EEPROM saved settings and display them onscreen or in some log file.

The reason I want to do this is to have like a backup of these settings to revert to in case I mess up and store some wrong setting in EEPROM.

Is there such a command?

Will M503 do this for me?

In pronterface you see the eeprom values everytime you connect to the controller. Wonder why this is different in Repetier?

In Repetier-Host, under menu Config is Firmware EEPROM Configuration. This will not only display the values in EEPROM, but allow you to change them.

M503 will print out the currently active settings. So if you boot up, it will load values from the EEPROM, and when you give it a M503 you can see everything.
