Hard flash the NEC 1300A firmware to 1100A

Hi All,
I was bought a NEC 1100A last 2 week and I am interest to
make it to a + - DVD writer. Who can tell me the part no. of the
flash rom on NEC 1100A PCB??.
I am plan to extract the .BIN file from the NEC 1300A update
program when it release (use Winrar can extract the .bin from exist 1100A update program) and use the EEPROM programmer to write a firmware to 1100A to see it is work of not…If anyone can hack the update program it will better
