9800 GX2 Bios Flashing

[aquariuz]

hi guys, first time posting here but I seriously seriously need your help here, n hopefully at least one of u have done an Nvidia GPU bios flashing lately.

I have been thinking about flashing my 9800 GX2 bios with a modded/OC'ed version of it. I use Nibitor v4.5a to extract the bios off my GPUs (there's 2 bios apparently, i assume due to the dual GPU), changed the clockrates n voltage n the fan speed on each of them, and I save them as rom files. I call them i1mod.rom and i2mod.rom.

Now I am using nvflash v5.63 dat i download off guru3d.com. However i have been having such a hard time with it for the past 3 days and no matter which version I use, it just keeps giving me problems.

First issue, I cannot use nvflash to create a backup of my bios (see pic below). Everytime i try it i keep getting the same error, dat write eeprom to file failed, I/O error: Cannot create file.

2nd issue, ok so I use nibitor to do so, n now i have a modded bios, n i wanna flash it onto the GPU. I get this error: I/O error: Cannot Open File: i1mod.rom

I've ran nvflash -r before hand but it doesnt do any difference. I see under help dat there's lots of other options but I dont wanna mess around with something I dont know.

I dont know if it has anything to do with my flash drive or how I booted into DOS (I use those tool discs dat comes with a brand new boxed HDD). Those are the only options i have to boot into DOS since I do not have a FD drive.

I really really do hope dat someone here could help me with this since there's not much found around the net to help me through it. Please help

nvflash -4 -5 -6 file.rom were file is your modded bios

Aquariuz :

1. Reboot into the BIOS
2. Go to advanced bios features
3. At HDD boot priority will see your usb flash device than use + to highlight it and move
to the frist .
4. After that at the 1st boot device : highlight removale

Now i think you can update your 9800GTX ^_^ ?
I'm use the same 680i sli MB like you.

Hi Zee, i'd help u but first of all, arent u posting under the wrong thread? I think Admin will move your post n make a new thread of it or something. Then I'll reply back to u there. First of all though, in your user CP, edit your signature, n put in your system's specs, just like wat I did to mine. It helps us who's trying to help u know more about your system without asking questions.

oh wait, my bad, i didnt know about the system spec link under the user name lol. forget bout wat i said then hehe.

TPU has a nifty System Specs drop down menu right under the user avatar
though I admit it would help if he used a bit more detail

Alrite, got it to work I dont know which one is the solution but i followed wat Solaris said n renamed the roms to simple no number names. I called them amod.rom n bmod.rom for each gpu.

n then i used my usb floppy drive to run nvflash n everything worked out fine. backup n flashing works.

Here is wat GPU-Z sees:

thanks again guys

[ZeE23]

[Solaris17]

ok well im not going to lie i dont quite understand you but you said you want a bios?

well you can dump yours.

Get GPU-Z here
http://www.techpowerup.com/downloads/1153/TechPowerUp_GPU-Z_v0.2.7.html

and when you open it up like in the pictures above on the main page click the microchip with the green arow to save it.

then get nibitor
http://www.softpedia.com/get/Tweak/Video-Tweak/NVIDIA-BIOS-Editor.shtml

so you can edit your bios to the speeds etc that you want

then you get nvflash
http://www.techpowerup.com/downloads/1127/NVFlash_5.67.html

and make a bootable floppy or usb drive put your modded bios on it and nvflash and boot from it then type

nvflash -4 -5 -6 mod.rom

and your good.
