LD Firmware Mini FAQ

Q: Which NEC firmware is this firmware based on?
A: This firmware is based on 1-08 Bitsetting firmware with version and name string changed to ND-4551A 1-X3.

Q: How do i flash my drive with this firmware?
A: The firmware is now bundled with Liggys Binflash Unzip then run the package, now click on the FLASH button. The firmware will now be uploaded onto your drive, when completed you will be prompted to restart your PC.

To Flash a drive in DOS, LINUX or MAC. Use a current version of Binflash. Run Binflash with the commands necessary to load the firmware package. Binflash will accept either a .BIN or a .EXE file and flash your drive.

Q: What are the risks of flashing my drive with this firmware?
A: Great care has been taken to make sure your drive is not damaged in any way by using this firmware. However, you flash your drive with this firmware at your own risk. Neither I, Liggy, or cdfreaks will be held responsible if your drive or media is damaged in any way.

Q: Will flashing my drive with this firmware void my guarantee?
A: Yes, flashing your drive with any unofficial firmware will null your guarantee. If something should go wrong with your drive, you should buy a new one and not RMA the drive.

Q: Do I need special IDE drivers when running this firmware on my drive?
A Like all optical drives. It has been proven they work best when using Microsoft’s default IDE drivers. This is a must for this firmware.

Q: Why do i not get good results when i burn media on the modified media list at MAX speed?
A: This is largely down to the quality of your media. If the speedups don’t give you good results. Set the burn speed lower. This firmware will give good results at the stated stock firmware speed, without having to flash back to a stock firmware.

Q: What about media not on the modified media list?
A: All media both SL and DL not listed in the modified media table use the default NEC STOCK write strategies and speeds. If you don’t get the results you expect with media not in the modified list, this is a limitation of the media or drive, not this firmware.

Q: How do i set SL bitsetting for +R media?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Q: How do i use DL +R bitsetting?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Q: How do i use DVD+RW bitsetting?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.


Q: Does this firmware support the LabelFlash labelling system?
A Yes, but special software is required to support LabelFlash.

FUJIFILM 8x DVD+R @8x :flower:

Hi… Ive just got my 4551a with firmware 1.07 and i was just wondering if i flash with this new modified firmware can i easily flash back to the official NEC firmware when the next one comes out??? Thanks.

Awesome! I’m really flabbergasted…

The only reason i asked was i flashed my pioneer 110 with modified buffalo firmware and could not flash back to offical pioneer firmware???

Then you’ve used a wrong flasher and/or firmware.
The official Pioneer flashers will only flash drives with offical firmware, ever!

OK…So back to my original question,if i flashed my 4551 with Firmware V 1-Z1 can i still go back to offical firmware??? Juat asking cause dont wanna get stuck with using modified firmware…Thanks

Of course you can, by using not-offical flashers like Binflash or TDBs DOS-flasher.
I suggest to create an backup of the current firmware before flashing a new one to the drive. :wink:

Cheers Chef Sorry If You Thought It Was A Dumb Question But I Just Needed To Make Sure,Gonna Flash Now And Give It A Whirl…Thanks Again

Fuji DVD+R burned at 8x. Strategy is not changed in this 1-Z1 firmware.

Nice scan. That’s the good stuff. :wink:

Sad that there is no support for MCC04 Discs.
These are rated at 16x speed, but Nero only wants to burn them with 2,4x speed.

Still testing my new 4551 with the Z1 Firmware.
Some scans will follow

They are rated at 16x in the firmware :confused:

On top of the box they are labeled as “16x certified”.
It’s a Verbatim Photo DVD+R Printable 25 Pack.

I use NEC Edition (The one that came with the drive) but it let me burn the disc only at 2,4x speed.

DVD Info Pro shows under Media Info
“Manufacturer Rated Speed 16.0x 22160KBp”

Verbatim MCC04 16x@2,4x

Something must be wrong with your DMA settings. These discs must not be burned at such a low speed, but 8-speed minimum to get good results. MCC 004 can never be this bad? :disagree:

Ok, at first I’ll try a Nero reinstall.
