Bought a bc-5500S need help



bought a nec BC-5500S on ebay the drive works fine…it has FW V.1.83…nec`s current fw is 1.04 so i guess this firmware is from a pc manufactuer…but who? there is no labels on the drive! is there a way to flash the nec firmware over the existing firmware?


Hi… according to this 1.83 is older than 1.40. I have bought HP dv5 notebook with BC-5500S drive. When i was trying to flash 1.40 bios from optiarc over the 1.83 flasher show there was a problem and bios wasn’t upgrade. What to do to upgrade to 1.40… Please help.


Beware crossflashing with slimtype drives!!

Only use the correct OEM firmware.
