We all know that DVD/CD writer can get more function and improve
the quality of burning by updating it firmware.

NEC ND-3550A is an old model DVD writer. And it also is popular in
the market. NEC ND-4551A is an upgraded model of ND-3550A.
The difference between these two models is newer model support
DVD-RAM burning and LabelFlash. In my point of view, it is not
worthwhile to buy a new model (ND4551A) just for DVD-RAM supported.

There is a way to upgrade your NEC ND-3550A to ND4551A by
updating the firmware in just few steps.

Step 1, First, you need to download modified ND-4551A firmware,
Flash Utility and bootcode Flasher. These are 3 main programs.
Uncompress them to a same folder. They can be downloaded from
here http://nechack.host.sk

Step 2, run CMD (Command Prompt) in Windows XP. Change to the
folder which created in Step 1.

Step 3, Run necbfl, enter your DVD-ROM path (eg. E: is the DVD-ROM
drive, the path should be like this \\.\e:)

Step 4, Choose 2 (upgrade to ND-4550A) or choose 3 (upgrade to ND-4551A);
Then press Y. Upgrade process will be run.

Step 5, Please reboot your computer after the process finished.

Step 6, You will see that the status light of the DVD-ROM is flashing.
Don’t worry, this is normal. Run binflahs; then click on Flash.

Step 7, reboot your PC; Done.

Please notice, the warrantee of your DVD-ROM will be violated
after you flash in the firmware. Take your own risk.
