Hey guys... I'm in modding mood, again, hahaha :D

Got my hands on a Nvidia 470m and put it in a G73JW. Unfortunately Windows won't boot.... "Valid MXM structure not found".

Does anyone of you have any idea about this? Every idea is greatly appreciated.

Here's all the info of the card that nvflash gives me:

Btw, I'll try the 6970m again later, maybe I messed up something last time... I mean it did boot with the 6970m...

Modified vendor and subvendor ID in vbios and flashed, no change. Well, I didn't really expect it to work, but was worth a try I guess.

Edit: I also just tried some rather unusual mods, changed Device ID etc. to the one of the Asus 460m, flashed successfully but still the same error and Windows won't boot...

I have no idea how they restricted this system.

Yeah, I did. What he changed is the adress that causes the system to make a beep sound during the error message... the card already worked on the system, but the beeping annoyed him, and since he couldn't find a way to deactivate the error message he at least disabled the beeping. So this won't help unfortunately.

Yeah, but this will only manipulate the countdown of the error message (set it to 0) and disable the beeping... this is helpful when the system boots anyway, so you don't have to watch the 30 second warning everytime you boot.

Damn, Asus, what did you do to this system? Why can't you apply to standards...

so those are in fact useful if you can get the card to boot after that message, right?

Yes, if Windows booted and the error message still showed up I would probably be able to more or less disable the error message with these tweaks you posted, but first of all I need to be able to boot Windows with the 470m. I have no idea what Asus did with the system... something is restricting it to only the 460m it seems.

I try to think of a way to exclude the BIOS and leave us with the VBIOS but you already tried to change the Device ID...

      Hello.
      I know this could be quite old , but I'm trying to install a GTX660M 2GB GDRR5 in my ASUS ROG G73JW , hope to be able to make it work.
      The reference chart is this:
      80.07.39.00.0F
      I got to ride with the heatsink and modified G73JH laptop starts but gives an error of VBIOS , must understand that flash the VBIOS new graphics card .
      Has anyone tried to put a GTX660M 2GB in this notebook ?
      Can this be done ?
      I read all the post 2012 on changing GTX660M GTX460M to 1GB, but I wonder if you can put a 2GB and if there is modified for her VBIOS .
      Greetings and thanks.

      The LCD stays black, no display but the external monitor works normally.It seems not to be the "backlight", the "F8" function key does not alter the problem.
      Does the video card deliver signals to the LCD AND the external monitor connector?
      Thanks for your help

      Hello there!
      I have this notebook since 2/11.
      Since July of this year, the screen started to go black during normal use, and a message appears telling that the an error occurred to the nvidia driver. I've tried a lot of different drivers, but the error persists.
      In a long playing session, when I quit the game, sometimes the screen show some artifacts, as you can see in the attached pictures.
      Did anyone had this problem before?! Is my Asus dying!?
      I'm willing to give a try on the 660M mode, but I want to make sure that this is only a vga problem that I have, not a general failure!
      Thanks a lot!

      We (me and a friend of mine, G73JW owner) just put a 6970m in the G73JW to see whether it works. The system POSTed and loaded Windows, but unfortunately the screen stayed blank
      Some background infromation about this whole story... When I exchanged the CPU of this machine a couple of weeks ago I decided to take a look at the GPU as well, as the system was already disassembled. (Note, it's a real pain to take apart this machine... totally unlike the AW systems... you have to tear it down completely, take out the mobo and then turn it around to get access to GPU/CPU...)
      Anyway, the GPU has nothing to do with an MXM-card... except for the connector which seems to be the same (at least physically, I have no idea whether it's the same electronically)... but see yourself:


      As you can see, the connector is physically identical, but the die is positioned differently than on a standard card... As the G73JH has the GPU at the MXM-conform place we got a heatink of the JH model. After some cutting and grinding it did fit the 6970m. The problem was that you can't fix the card with screws since the holes of the G73JW 460m are at totally different places... but that's nothing a little bit duct tape cant fix The important thing is that the heatsink can be screwed on very well.
      But well, like I said, it didn't work... a couple of hours work for nothing. So we had to disassemble the system one more time to put the 460m back, lol.
      I knew the chance of the 6970m working was small... but since the G73JH (5870m) can run with a MSI 5870m as well, I thought it's worth a try.
      Maybe it's only an issue with a hardware ID, I have no idea... like I said, POST was fine, system booted, but screen stayed black.
      If anyone of you have an idea to get it working, let me know!
      There are two more pictures as attachment which show the 6970m on the mobo and in the system, if you're interested... just as "proof"
