It seems odd that the following statement is the same in both read and write functions:
i2c_SendAddress(ROM, 0);
Why odd? , you need to write address in both cases.
In writeAt(), i2c_Stop() presumably initiates the self-timed write (5ms or thereabouts?).
thats right.
Without seeing the bigger picture, I'd ask whether you could be trying to read before the write has finished.
I thought about that so I waited for 10msec, even 100msec but still unable to write.

How soon are you turning back around to read? Are you using a simple write completion timeout or are you write-busy polling elsewhere to pace EEPROM operations after the write?
good suggestions but for now I only write one test byte and read it to verify.
I even implemented this pageWrite test routine and read the eeprom through external programmer and still no write!
