dumped the LaCie eprom

I received the CH341A EEPROM Programmer today. The kit I ordered contained two PCBs, one to solder the LaCie EEPROM on and one to read/program its contents. After some (de)soldering and finding the correct software I successfully dumped the EEPROM.





The proof is in the binary dump, a short analysis shows me that LaCie isn't doing anything special here (like patching the NEC uPD720133 firmware), so we will simply replace the LaCie strings with something to our liking, update the firmware CRC and go from there..
