Sorry, I forgot about this post. Anyway, this is very strange. All the diagnostic testing goes absolutely perfect but the actual flash doesn't work. I mean nvflash detects your card and supports your EEPROM but it still doesn't flash. I've never seen this before.

Just curious, why are you flashing your card? If the card still works just fine then attach the current rom it has on it and the new rom you are trying to flash.

The card isn't working. I see graphic tearing on the screen and different kind of patterns.

Sorry, I'm unsure what to say. Unless the card is new then its probably gone bad. Flashing the card most likely will not solve anything.

I'm assuming you've tried to use 'nvflash new.rom' and it asks you to press 'y' and that still doesnt work. If you find anything out be sure to come here and update me because I've never heard of anything like this.

Question. If I were to use nvbitor to change the "name" of my 3600M to 7950 go gtx, would that actually affect anything? I just did a small test with my 7950 go gtx to 8800gtx, and upon loading it it was total jibberish but integrity was still green. Also when saving back to original 7950go gtx and reloading it seemed completely normal again. Still green integrity. If I did this, would it more than likely break the vcard? Or would it work just as a 3600M, except with the name 7950 go gtx. I want to try this in an attempt to trick the bios.

The reason you are seeing gibberish is because there is no actual place in the rom where the name is stored. What's actually happening is you are changing the device id from 0297, aka 7950 go GTX, to 061C, aka 3600M. This in itself is no problem but nibitor most likely translates this device id to a gpu architecture. Essentially, its parsing your 7950go GTX rom, which has NV4X architecture, as a 3600M rom, which has NV5X architecture. Its good to remember however that nibitor is a 3rd party rom editor and as such has no real ties to how nvidia actually works with your rom. I won't go into details but there are other ways to parsing the performance table, voltage table, and temperature table that Nvidia most likely uses. Therefore, those tables should still be read fine by the computer although they are read as gibberish by nibitor.

I don't have the knowledge to tell you if everything will work smoothly though. From the bios perspective, everything looks decent, but I don't know how things will work from the driver perspective. I could test this all myself but I don't know the next time I'm going to open up my computers.

Well. If I gave it a shot what do you think the chances are that the dell bios reads the device id and nothing else to determine compatibility? That said, any good way of making an automatic cd that will flash upon booting back to the original biois in the case of blind flashing which will probably happen :P.

I have a 3600M now to do testings on

I thought someone may have tried this before, but the more I think about it, the more I think I'm mistaking. Anyway, there's actually a really good chance that all Dell uses is the device id. Every tool I have ever made or every tool I have ever seen the source code for only uses the nvidia id (0x10de) and the device id to identify the card.

To make an autorun cd you just need to look back on the first post under bootable cd. It has instructions for modifying the autorun.bat, a file that is executed automatically once the cd is booted to.

Sorry for the late responses. You should be fine with just modifying the device id but if you do anything crazy I have a setup to recover these cards.

I have a feeling this could be the smartest or the stupidest thing I'll ever do to a laptop.

It almost seems like you might have to chainboot to get everything to work correctly in the BIOS and in the OS. Anyway, we can ignore that for now. Don't be too worried; I can most likely recover your card myself if you mess anything up.

Chainboot? Well I can try as soon as I get a new hard drive. I'm putting win 7 on and attempting to upgrade with the 3600M, again attempting.

Anyways, I'm waiting on you zzpulp to answer before I do this about what and how to do this chainboot what notness, before I go ahead and see if we can advance the e1705 one more time

Oh you can ignore that for now. Just try it out without chainbooting and if problems occur with performance then maybe I can suggest some solutions.

So what exactly should I change to make the bios think this is a 7950 go when actually it'll still work as a 8800M? In nvbitor? Just the name?

Uh I don't really use Nibitor but I'm pretty sure thats all you need to do.

I just tried this.
I edited the 7950 GTX device id into the 3600M rom and flashed it. The card would not work anymore but that didn't worry me. I then put the card into my M1710 and it failed to work there either (no surprise). I proceeded to blind flash the 3600M stock rom back to the card while it was in the M1710. When I rebooted the card was working but the brightness was low. However, the brightness was not nearly as low as when I swapped the cards the last time (without flashing). It was definitely a usable brightness for indoors, either the default minimum brightness or slightly higher. This is when I got lazy though. I booted to Linux but didn't use the nvidia drivers. I'm unsure whether full power 3D will work with the card.

Sorry for bring an old topic back up but I have a Sager NP5793 with a dead 8800m GTX. I've bought an HP Quadro FX1600 which apparently has a special BIOS so it only works on HP's. So I'm trying to flash it's bios to a dell fx1600 version. Problem is with the card in my laptop it just beeps 11 times and then turns off, I cannot get anything on the screen. I tried this blind thing but with the USB in and HDD out it does the same, beeps 11 times and turns off. I can't get it to flash... Any suggestions?
Thanks!
