LD Firmware Mini FAQ

Q: Which NEC firmware is this firmware based on?
A: This firmware is based on 1.06 Bitsetting firmware with version and name string changed to ND-3550A 1.Y6.

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.

I was just about to ask since I just saw this pop up on your page…Thanks Dee…

CMC MAG AE1@12X with 1.Y2

TYG02 @ 12X with 1.Y2

CMCMAG E01 @ 12X with 1.Y2

MCC003 @ 12X with 1.Y2

Can somebody send both 1.Y2 (Orig and RPC1) firmwares to
Still have troubles downloading from Liggy’s site. Thanks!

Thanks for the firmware :flower: and other stuff :eek: :a

CMCMAG AF1 @ 8X with 1.Y2
A little fast for this batch. I never really liked this media anyway…

JPNR01 @ 12X with 1.Y2.
A little rise at the end but not too bad for a 4X media @ 12X.

1.Y4 Firmware Released

Grab it here

For full details see the documentation supplied or view the first post in this thread.

What happened to version 1.Y3?

I started work on it but didn’t have time to complete it. 1.Y4 uses identical strats to 1.X4 for the 4550 drive. :wink:

All we know from Liggy is he can’t release the 3550 to 4550 upgrade…is the reason being NEC will get legally involved or get in trouble for the licensing issues involved with DVD-RAM? Just curious as to the reason…thanks!

Thank you, will check this out

does 1.Y4 support bittsetting?

Now that Dee has released firmware with the same write strategies for the 3550 as for the 4550, the only reason to cross-flash is to get DVD-RAM support. I’m not at all sure that DVD-RAM is any kind of a big deal, at least not for me. YMMV

of course/reread top of thread/

thankyou Liggy & Dee

nec 3550 1.Y4 burn at 8x nero6.6 18
scanner 1620 oem xflashed to pro
would have been a 99 except for spike at 2.8 gig

scans of burns with stock firmware not as good

:clap: :bow: :bow: :bow: :bow: :bow:

the one thing this 3550 doesn’t do is burn well on TY 02 or 03’s
low 90’s as tested with stock and new modded
better on my benq. lg. and nec 3520/40’s
