Is it a Blue or White ?

Check my website as i have a link now for how to detect a clone !

Well the fact that the chip works fine in another machine means the chip is ok.

"Manufactures ID 90 Device ID 90
!!Unknown Flash Type !!".


In all the posts on here i have never seen this message ... Ever ! ID 90 Device 90 stumps me !

Remove all wires and clean up with solder wick. If it's a V1.6 redo the lpc rebuild - if you used a rebuild board then pull it out and use wires.  start again and use the alternate points like in my duox2 install guide here

 But ok lets look into this further. Have a good look at the flashrom ( the square black chip with AMD or FUJITSU or HYUNDIA printed on it ). What numbers does it have on it ? They will be a bit hard to read you might need good light / mag glasss etc.

Is it any of these ?

0x01d5,"AMD - Am29F080B",0x100000
0x04d5,"FUJITSU - MBM29F080A",0x100000
0xadd5," HYUNDAI - HY29F080",0x100000

If it is then it has a proper flashrom but maybe it's faulty !

If it is this one ...

0x20f1,"ST - M29F080A",0x100000

Then you have a clone of poor quality ... get a refund or demand an original chip. Original chips are only supplied with one of the above 3 flashroms !

I do MASSIVE ammounts of hotswaps.
I find that the pins in the female pinheaders eventually get tired and don't connect well. The chips will boot from the bios fine, but won't flash properly.

So what do I recommend?

Try double checking the soldering of the pinheader to the chip. If that doesn't work, I'd try to swap the pinheader off of the chip with a different one. Or try a wire install even.

Maybe a trace has been damaged on the chip?

So many variables.

Good luck to ya! If you could let us know if it's a clone or not that would be helpful as well.

Well, if you can verify that all traces are healthy and that the pinheader is properly soldered to the chip, then I'd say the chip is faulty, and you should contact your supplier and ask for an exchange. You may not get it, but it doesn't hurt to try.

That's because he probably means 09 00 which means the chip is reading flash core space not register space. 09 00 are the first 2 bytes of every bios right? Those are not the jedec device ID's in the first 2 bytes of register space.

 just kidding !

The_Myrddraal ,

Does it say ...

"Manufactures ID 90 Device ID 90
!!Unknown Flash Type !!".

like you previuosly said or does it say the more popular ...

"Manufactures ID 09 Device ID 00
!!Unknown Flash Type !!".

HackDaBox !

PS of you do get 09 00 then one of the connections is not making a good contact. Also try flicking the switch back and forth a couple of times !

     No, it says 90 90 on either bank, tested on both Xbox's.  I have contacted the supplier and I can send it in for an exchange.  I felt right away it was the chip account the fact I had never run across it before.  I, being the perfectionist I am, was just responding to someone with the same problem as mine.  I figure since there was a post the same time I had the problem that possible there was a bad batch of chips going out and we were just the lucky two that noticed the problem first.

lol
you beat me to the punch.

[The_Myrddraal]

     Well I have the answer finally!  I just couldn't give up on it.  I will say I was at my last straw though.  I thought I would look the chip over before I shipped it off today.  I started to notice something didn't look right on the right side of the AMD (Am29F080B) chip.  I got out the old 5x flouresent magnifier and took a long hard look at it.  I though I could see a little solder behind one of the surface mount feet that may be bridged.  I kept looking and looking, then it looked like one foot wasn't connected on the bottom side of the chip.  I turned it sideways and noticed (to my surprise) it wasn't soldered on the whole right side of the chip.  It was laying flush with the solder pads but none had ever been soldered.  So did I send it in.  Hell no!  I soldered them all in and it works fine now.  That was real fun account my eyes aren't what they use to be.

    EsspeN I hope this helps you out with yours if you haven't already sent it back.

Nice work!

Omega are slipping :-P

I am having the same problem with my duox2. I have a cromwell edition with an AMD chip. I did check the solder on the pins and they are fine. I have tried a hot swap ect.
I swapped out the duox2 with another and it boots, so I know it is not the pin header.
I think I have a bad chip. It may be a bad batch.

P.S. I think two of the legs are suppose to be bridged.....
