Hello mate, I will be thrilled to help.
First thoughts are that it's not going to change to the FX3700 as the 8800gts is different to the 8800gt. I shall see if I can find out what the equivalent is.
On any page, the top part has device and vendor as variables. Set device to the right quadro, and vendor to whatever you please. I left mine as evga
Under clock rates, set to whatever you want your card running at
Under adv. info is the most important part,
Device Id changes to that of the new card
Sub vendor id has to match the vendor, so set to 10DE if using nvidia, or do not change if leaving set to evga
Sub system ID does not change
Board ID does not change
The difficult step is working out which device id to use. So this is what will take the most of out time.
When you make the floppy disk, it'll have a load of files on it to start with. You add nvflash, another little file the name of which escapes me but it came with nvflash, and it's mentioned by name as missing if you try to flash without it. You then add your new bios file.
flash with nvflash -4 -5 -6 name.rom, y, y, reboot
Probably not needed but wise is to remove all geforce drivers before flashing, then install quadro drivers after the flashing is done. Otherwise the drivers fight with each other. Id personally do the cards seperately, one sitting outside the case while I flash its brother. Not required, and takes a bit longer (especially the driver uninstall with required reboot after each and every time), but safer and easier.
I'll head over to mkvtech. How much ram do your cards have? I'm going to assume 512, since I think the other sizes would mean G80
8800gts G92, 65nm, 754 million transistors, 135W, 128 shaders, 16 ROPs and 64 textures/clock, 256 bit gddr3

Ah. There isn't an exact match. So, this is going to be breaking new ground. I propose you attempt to flash to 8800gt. If this is successful, everything is good and you can then flash to fx3700. If it's not successful, you're going to see all kinds of mad **** on your screen when you try to boot from it. So, here's what to do, complete with numbers. Don't suppose you have msn do you?
Take off the sli bridge, and then...
1/Copy the bios off your primary 8800gts, and off the secondary. Number them, and stick pvc tape over part of number 2. 88gtsstk1 and 88gtsstk2 for example. Flash the second one with the bios from the first, then swap the cards over and boot. Drivers shouldn't see a difference but might need a reinstall. This will work, and get you used to nvflash. You wont strictly need the -4 -5 -6 options but type them in anyway.
This is to give you two identical cards, so if all goes **** up you can flash the working one to the not currently working one.
2/Copy an 8800gt bios, a real one, not hacked about with, onto the floppy disk. Flash the primary graphics card with this (covered above somewhere, I think its a case of typing 1 or 2 near the start of the command. I'll read the helpfile if it's not obvious). I'll email you the appropriate one, it'll be at stock clocks if you don't specify otherwise. It'll call itself nvidia. You're welcome to source your own instead, the one I send will be a downclocked version of the 512 original from
here, though I can dig out my old 8800gt evga bios if you like the nvidia is more likely to be compatible.
So now you have a known working 8800gts, and one card that thinks it's an 8800gt which may or may not work. Boot with the 8800gt in the primary slot, hope for clear screen and no corruption. I reckon a 70% chance of this being fine. if it's all buggered, turn off, swap the cards over, breathe a sign of relief at the post screen then flash the 8800gt back to the 8800gts bios. Swap cards back, boot, note all is back to normal. However we're then back to the drawing board and will need to be more cunning
3/So, hopefully it's now an 8800gt. Excellent. Remove geforece drivers now and reboot, then turn off and on next boot you flash it again, to fx3700 this time. Take the 8800gts out or the drivers are going to get
really confused. Boot, install quadro drivers, verify all is well
4/Turn off, put the 8800gts in instead, flash to quadro, boot and notice that XP hasn't noticed a hardware change.
5/Put both in, boot. Check all good. Then turn off, put sli bridge on. And then we get to find out how to get sli working on these, maynard V has two fx3700 but no sli board, I have an sli board but only one card.
So, you get to do things people haven't before, offer a really useful piece of information to the public domain, and discover a distinct feeling of fear while waiting for it to post.
Please respond with any questions, the above is long and detailed only because I want to make very clear that this is done at no risk (the bonus of having a second card), should work, but may fail and leave you frustrated with the same sli system you have now
