Change log
1-Z1 all new firmware.
The object of this firmware is to burn some of the most popular 16x and 8x media with better quality than the stock NEC firmware. In most cases this has meant slowing down some 16x media and using a Z-CLV writing method.

This firmware is only compatible with NEC ND-4571A
DO NOT try and FLASH a ND-3500, ND-3520, ND-3530, ND-3540, ND-3550, ND-3551, ND-4550, ND-4551, ND-4570 drive with this firmware.

LD Firmware Mini FAQ

Q: Which NEC firmware is this firmware based on?
A: This firmware is based on 1-01 Bitsetting firmware with version and name string changed to ND-4571A 1-Z1.

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.

Note

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

Submitting test results
Please state the LD firmware version used for the burn, the media type (MID code) and the burn speed.

If possible burn a disc with NERO CD-DVD Speed (create data disc) and save the burn screenshot by clicking on the disc icon at the top of the window.

Also submit a (data transfer test) Using the ND-4570A, ND-4550A, ND-3540A, again saving the screenshot from CD-DVD Speed

Disc Quality scans can be submitted with NEC Drives using CD-Speed with scan speed set at 5X or 8X
Note Version 3.75 or higher is required for PI/PIF scanning on the NEC drives.

Below is some additional info from the author of CD-Speed.

(Liteon drives) using K-Probe @4X scan speed or CD-DVD Speed (disc quality) @4X scan speed.

ET


#4

waiting to see some scans … maybe then i’ll buy a new 4571… :bigsmile:


#5

Pick a media from the modified media list, i’ll burn one if i have the media.


#6

Great, thank you!


#7

Installed the 1-Z1 RPC1 version firmware on my original 4571 drive and rebooted my PC. After that I inserted a blank DVD and my PC froze!!! Had to reboot to get it alive again. Will test with the 1-Z1 original and let you know.

[B]Update:[/B] The 1-Z1 original works! So maybe I did something wrong overhere or the RPC1 is faulty. Could somebody please check.

Verbatim 8x DVD+R MCC 003 burned @12x
Scanning done with 1ECC to compare with LiteOn. First at MAX speed and second at 8x.

PS> Notice, that the spikes are exactly, where the burning speed drops…could IT be the problem of spikes?? Or I should not worry about the spikes. Wheen don’t look on the spikes, it’s a very good scan, isn’t it?

#13

i was just about to moan that an .exe is no good on linux, but just noticed that binflash for linux can now handle them, and also set the booktypes (bitsetting) nice one!


#14

Hi Dee, is there any reason why the Verbatim MCC 03RG20 has gone down to x12 from x16?, is this part of the writing stratigies from NEC?

Many Thanks

Bart


#15

WOW, I take it that no one has the 4571a?

Bart


#16

The whole point of this firmware is to improve writing quality by dumping the 16x write speed, and changing the 12x writing strategy from CAV to Z-CLV.

MCC 03RG20 is one of the MIDs that have been modified in this way by Dee in this firmware. Please look at the very first post in the thread! :slight_smile:


#17

My apologies DrageMester, I should read before jumping in feet first. My ignorance deserves no feed back.

Many thanks

Bart


#18

No need to apologize. :slight_smile:


#19

Memorex 16x, burned at 8x



#20

@Dee,

Is it possible for you to speed up the “INFOME R20-000” from 8x to 12x? I got a batch of Philips DVD+R 8x overhere ready for testing.
