Which board jumper setting i should check?
Voltage was solid 3.30 / 5.10 / 12.05 volts so i don't think voltage even matter. disconnecting the GD-ROM/CF gave me "ERROR 24 GD-ROM NOT FOUND" error message.
- Thread starter TylerDurden67
- Start date
put that at 3.4V and see if it helps
the jumpers inside the DIMM board should be in "GDROM mode" like this: http://www.gamoover.net/files/image/Tutos/NaomiCF/Jumper_GDROM.jpg
I think that jumpers for net-dimm daughter board not regular dimm daughter board. here is my regular dimm daughter board's picture if it would help.
Increased voltage as you said but still no difference but now when i put my net-dimm daughter board back it giving me "ERROR 04 BOARD MALFUNCTIONING" instead of loading game.

sometimes,you got weird stuffs like this
specially using old firmwared dimmboard

That sounds reasonable, since i upgraded regular dimmboard which came with 1.02 firmware.
btw, i also have same issue with net-dimm board (firm ver : 4.02/initial firm ver : 3.17) /w regular dimmboard daughter board. so i guess its firmware bug on specific dimmboard.

you're right too
I even got somes dimmboard that doesnt works using GD daughter board with firmware >3.17
Maybe due to somes settings stores on it or simply old révision of the board

Right. Excuse me being dumb! Any help appreciated.
There is so much information that you clever chaps have brought together... Mind blown. I have tried to understand as much as possible. As a noob to Naomi I have managed to source power supplies cabling DIMM, Motherboard and JVS JAMMA interface. CF Zero Key and PSU cable from Mitsurugi-W. Some of this is still shipping, but I am looking at my DIMM.
The label is FPR-23489C and needs to be changed to firmware 3.17 which I can do by swapping the TSOP. How then do I upgrade to 4.02 to run CF based games? Do I HAVE to have a NETDIMM to get to 4.02?
The two boards on the DIMM are 837-13987-02 and 171-8079B

Yes, you do.
Noob question that I think I already know the answer to, but I still want to ask.
If a DIMM board has a TSOP 56 flash chip, are there any jumpers that need to be set to be able to use a TSOP 48 flash? (I am guessing the answer is no)
I have two DIMM boards that I tried converting from 56 to 48, and both get an ERROR 22 on boot. I have checked solder many times and I know the chips were programmed correctly.
To make sure I didn't kill the board, I put the original TSOP 56 flash back on the DIMM board and it boots great.
I converted a DIMM that came with a TSOP 48 flas, and it works fine.
Any help would be appreciated. Thanks

there ils no jumper for this configuration
Just use correct tsop 48/56 or équivalent from your dimmboard otherwise it wont work (error 22)

Yep. No jumpers. As long as it's a compatible chip, programmed correctly, and soldered well it will work fine. Just make sure to clean up the solder on the 56-pin pads.
@Mitsurugi-w, just curious if you still have the aftermarket Summit Arcade CF readers stock in hand.
I build a batch as needed.

Hi. If you like you can flash the 4.02 firm directly on the chip and solder it. I freed it on december last year on segaretro, but I see the page is down. If you like, you cand tell me an email adress and I can send it to you.
@Mitsurugi-w do you have those links so we can update them?

Does anyone have a good part number(digikey?) for the Farichild 16245? I'm having a hard time figuring out which is the "right" one.
