LD Firmware Mini FAQ

Q: Which NEC firmware is this firmware based on?
A: This firmware is based on Liggy’s 3.05bt with version string changed, with riplock removed and RPC1

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.

Thanks again Dee!!!


I do not see the write sratagy for TYG-02 as I did in 1UF. Did you eliminate any write stratagies or just add Daxon.


Dee-27: Can you post some scans of added Daxon discs… ? =) I don’t think I ever saw any scans of this discs.


thank you Dee and Liggy once again:)
@Quikee i’ve posted some results of daxon AZ2 (BenQ branded DVD+R 8x) and they were poor… maybe AZ3 is better:)


Why does my firmware now show Nec3520RW1UG


Is it best to booktype dvd+ to Book type dvd-rom


Well yes… this is why I want to see a scan… I know of Daxon AZ2 and I know they are poor but never saw a scan of Daxon AZ3 or any of Daxon DVD-R discs. Dee allowed to burn them at 16x… so they must be acceptable. =)


Thanks again Dee… :bigsmile:

… once again I ask you: :confused:

I was buying Intenso DVD+R 8x PRODISC R03
Could you kindly tell me your quality opinion of this DVD ?
Is still better to write them with 1.UG or using the NEC 3.04 firmware ?

NEC ND-3520A - Modified vs. stock firmware - DVD+R writing

thanks :bow:


MCC-004 Verbatim 16x


Your IDE controller is not set on DMA mode 2, you need to sort this :slight_smile:

I found mine burned best with modified firmware. try them and scan them with both firmwares and see what gives the best results.

Only burned them on the 3540, but the write strats are identical.


It’s set like this…


Here’s a scan of Memorex + branded CMC MAG E01 picked up a few weeks back for $8.97 @50pk. Burnt at 8X with this firmware. Opinions welcome !


Nice job!


Again, nice job!


I will give it a try this day. I have to burn some discs :slight_smile: and I can scan MCC 04 and TY 002. This evening I hope to post my results with the firmware!


It needs to be Ultra DMA 2. The used driver should be OK, but what IDE controller do you have?



I burned 3 discs up to now. I am very glad with my MCC 004 discs which are performing very well. About my TY T02 I am a little bit concerned, because they perform very bad (not only with this firmware). I think I have a bad load of them, or they are degraded in quality. Unfortunately :confused: … I think I am a Verbatim lover since yesterday :smiley: !

BTW: because scanning @5x / @8x does not seem to have any impact on the results, I scan @8x. It saves lots of time, because I scan almost every burned disc…

and the post is not 1 day old :wink:


@ Liggy

This time after updating I watched flying by on the screen, “1GF” while under Windows XP “1UG” is visible!

This is the first time that I see a difference between the DOS and Windows
mention, is that the way this time it should be? Or not?
I always do the update with 116winguiflasher…

I like to hear if you all has the same mention, it should then logical for me…
we all have the same error !
Or only I have an error… wich I don’t think.

I always check the DOS and Windows mentions!
