Testers needed: NEC 2500A Bitsetting firmware

vbimport

#1

I just worked on Beta 6 of the booktype firmware. This version is based on HP 420i 1.25 firmware :slight_smile: I implemented the +R writing strategies from the 1.06 NEC 2500A firmware.

Most common 4x DVD+R’s and 4x DVD-R’s should work @ 8x now, including RICOHJPN R01! It also has extra media support for previously unsupported 4x media!

Have fun testing!

Get it here:
Windows: http://herrie.rpc1.org/downloads/2k5107b6.rar
DOS: http://herrie.rpc1.org/downloads/2k5107b6dos.rar

Please post your results! Set the booktype with DVDInfoPro and burn with Nero 6.3.1.6!

Donations using Paypal are always welcome of course :slight_smile:

Heh, we are referring to ourselves in the third person now are we?

Go read about what bitsetting is here: http://www.dvdplusrw.org/Article.asp?mid=0&sid=2&aid=42

Herrie! Congratulations! Thank you very much for your continued work.

my 2500a is coming in this week, cant wait to test it out

Good thing:
Bitsetting works!
Tried DVD+R to DVD-ROM - works fine! My JLMS XJ-HD165H thinks it’s a real DVD-ROM and reads at full speed!!! Never done that with discs set to DVD-ROM by other drives (Lite-On and NU booktype also works but is read at 3,5x-8x CAV only). What’s the difference that causes this different reading speed?
DVD+RW to DVD-ROM also works fine!

Bad thing:
RICOHJPNR01 4x DVD+R only works at 4x now - worked at 6x before.
Writing quality at 8x seems slightly decreased for the part written at 8x.

:frowning: Herrie, can this be fixed? Actually, writing to RICOHJPNR01 at 8x would be ideal (of course) since the write quality at 6x is already excellent.


#9

That is the reading curve of the TY 4x DVD+R written at 8x with DVD-ROM book type.


#10

Ouch!


#11

Could just be that Recordable DVD-media is not good enough to be read at full 16x speed - here is another disc…

Thank you very much Herrie !

OK first Test results:
Good:

  • flashing worked fine

DVDINFOPRO:

  • changing the booktype of DVD+RW (RICOHJPNW11)
    to DVD-Rom worked fine
  • changing it back to DVD+RW worked fine
  • changing it to DVD+R worked fine
  • changing it to DVD-RW worked fine
  • changing it to DVD-R worked fine

Allready existing data on the DVD+RW was still readable after changing !

NERO:

  • changing the booktype to DVD-ROM worked fine
  • changing it back to DVD+RW worked fine
  • burning DVD+RW after setting drive default with DVDinfoPro
    to DVD-ROM and making a shuttdown worked fine

Bad:

  • DVD+RW (RICOHJPNW11) can only be written with 2,4 instead of 4 with the TDB RPC1 and ripspeed firmware !!!

Please use the TDB RPC1 + no riplock Firmware and include Bitsetting to get the best out of this NEC !

best wishes Prema:) :slight_smile: :slight_smile:

That would be very difficult… This firmware from Herrie is the HP 420i firmware with the namestrings modified to say ND-2500A. I don’t think that we will see bitsetting capabilities added to other firmwares, but TDB could always patch this HP firmware.

I’ll try and see if I can get the writing strategies from another 2500A firmware added to this one :slight_smile:


#15

Good to hear the 2500A can support bit setting now! :smiley:
Great work as usual Herrie :bigsmile:

Shouldn’t this topic should be stickied though? :iagree:

i’ve been bitsetting my RICOHJPNR01 to dvd-rom for a while now (big thanks to Herrie for that ;)) and have been able to read them at full speed in my 166S, so it can definitely be done. i guess it just needs to be of high enough quality.

Yes - but the 166S is a much better reader than the 165H.

That is why I use the 165H - it easier affected by the disc quality = will slow down more on marginal quality discs.


#18

ah, gotcha, i thought you were saying it couldn’t be done under any circumstance. it’s strange that lite-on and nu bitsetting don’t exhibit this kind of speed change. i hope someone can come up with an explanation.


#19

Writing quality seems good enough when writing at 4x to the TY discs.


#20

I already planned to buy this drive today after I’ve finished my work. Now I know that it’s the right decision to buy exactly this drive. Thanks a lot Herrie!
