Initially programmed the EEPROM with an image that has $FB09 corrupted.

Byte sequence there MUST be:

C1 F0 F0 EC E5 A0 DD DB

which translates to:

41 70 70 6C 65 20 5D 5B
 A  p  p  l  e     ]  [

Just make sure when programming EEPROMs, the correct sequence is used.

Verified bug and fix on Rev 2 hardware.
