The CopperRocket board has a 93C46 type EEPROM on it which stores 64 16-bit
words of data.  The EEPROM is attached to the system via the Ethernet chip, but
it isn't programmed to auto-configure the latter and it appears that CM's
original usage of this EEPROM (which isn't totally clear) included functions
not related to Ethernet per se, so it is probably best thought of as a system
component standing on its own independent of Ethernet.

The approach taken in the Hack-o-Rocket project is to leave the EEPROM alone.
We never write anything to it (don't even have code to do that) and its content
is whatever is was before we turned the CopperRocket into a Hack-o-Rocket.  We
have figured out where the Ethernet MAC address is stored (words 2F through 31
hex) and we read it out of there, but that's all we do with the EEPROM.  We
don't understand the meaning of the rest of the stuff stored there and we leave
it alone.
