I was about to write some calibration constants to the Redboard's EEPROM but decided to first check that it was empty. There appears to be data (values other than 255) in the first 30 or so bytes. I haven't been able to find any documentation on what's using these locations. Is it Optiboot, random data from a manufacturing test, something else?

Thanks!

I can't speak to where the data came from but I have applications that use EEPROM from address zero. I have never seen a problem with the EEPROM being overwritten. I did a search to find if any of the bootloaders stored into EEPROM and never did find any documentation that they didn't. But then again, I didn't sift through the bootloader code.
