with a 24c65 NVRAM
I did not give you valid advce, my advice related to NVRAM as you stated you were using, you are not using NVRAM you are using a serial EEPROM !
There is oddles and bunches of postings on EEPROM do a search and you will find what you need.

ATTENTION:
If you look to the topleft of the post entry window you will see:

Professional forum -- Use your real name
Messages with aliases or handles will be deleted

DROP YOUR STUPID "HANDLE", use your name.
