Yes, I am going to pull the second EEPROM Today, and read it. That one does have OPT6, so maybe I can correlate what address I need to focus on. Another member of the group sent me a .bin that seems to suggest F7 F7 F7 as opposed to 01 01 01 might have been the second issue I am having. I only chose 01, because the address where OPT11 resides had 01 to activate the option. Let me see what I can learn from the EEPROM which has OPT6 invoked.
Hopefully something I can make a better understanding of what is going on once I have the second EEPROM read.
Thanks,?
Rich?

Rich,
the reason for not getting the results you expect is that you are assuming that 8753D and 8753E has the same EEPROM layout.
I recommend using the 8753D EEPROM layout as inspiration only and that you focus on analyzing the differences in the two EEPROMs you have, to find what bits to flip.
