Nvidia VGA Bios modification/flash/restore guide

What can I do? Do you know who can give a look at my bios?

 

im having an issue with copying my vbios onto a usb stick ..
ive reformated dropped the nvflash into the folder botted into my bios
options come up to boot from "ativa usb drive"
i get a command promt black screen put in
nvflash -b OLDBIOS.ROM
a:nvlash -b OLDBIOS.ROM
"nvflash -b OLDBIOS.ROM
all come back to me saying error and nothing copies

im using a g50vt a-2 9800m gs .. many people have overclocked these cards why cant i even get the bios ?

 

make sure you have enough space left in your usb boot disk to copy the bios.

 

You can also get the VBIOS with GPUZ.

 

i got 2 gigs of space ^.^

opened my bios with gpuz edited to gts clock speeds and volts
saved as NEWBIOS.ROM

loaded up my G 94 M.bin into nibitor and resaved as OLDBIOS.ROM
put files into the usb got to the boot screen pressing esc on splash boot from usb

typed in nvflash NEWBIOS.ROM and it gave me back the same error code ive been getting

bad command or filename is my error

 

I just checked the latest BIOS 0213 for the G50vt. The VBIOS(NVIDIA 9700M GT, Version 62.94.3C.00.15) is included in it, therefore you have to change the clocks and volts in the corresponding module in the BIOS. It can be done, but it is risky as you can brick the BIOS!!
You can overclock with the NVIDIA tools core, shader and memory, but not the voltages.

 

Well I downloaded winrar file tool and opened nvflash into my usb
That did the trick ...i belive the file never made it into the usb as an
.exe file
Now running gts speeds haven't run 3D mark test yet but ran ff14 benchmark test and everything seemed real stable gained 234 points from the 1987 score I was benching on stock

 

I've done this, flash with nvflash, the operation was successful but now the computer doesn't boot anymore.
Cd's light goes on, fan starts and then nothing happens. It's not just a black screen, nothing happens, I tried blind flash but the computer's not working and the flash usb isn't booting anyway.
Any solution please?
It's an acer aspire 5920g laptop with 9500m gs video card

 

You need to get it to pass POST somehow, maybe this will help:

Or it might be time to upgrade to an ati HD 4650.

 

A bit complicated for me
Any non-hardware solution? I've read about that "Fn+Esc" boot recovery for motherboard bios, might it help ?

 

try to remove battery/power cable & press power button for 30-40 sec. Hope that might help. BTW did your Vbios successfully flashed the card without force flash method? got any error msg?

 

No I didn't get any error, it went ok, got the message "Operation successful" or something like that, it rebooted and.. Nothing.
I tried to remove battery/power cable etc but it didn't work unfortunately

 

hello I am a newbie but I can't undervolt my 8400mgs 256mb pci card becouse I can't extract or dump my vbios. all the programs found report error. nvflash 5.xx all version tested report "eeprom not found" and the comand "pciblocks" sayse corrupted and the backup I finaly made is 0 kb with v-bios version unavaileble(invalid).
ok boys that is all I hope you can't help me with my problem becouse my graf card is very hot on idle. ife you can't help me? plese do it and thx great job all of you

 

Most likely scenario is ur v-bios is integrated to system BIOS. in that case you can't extract V-BIOS. BTW if your card overheating try to clean vents and repaste it. you can get more help from people if you can start new thread for your matter.

 

sorry for my english. but I have dane the clean vents and repaste my pavilion dv6000 and undervolt the cpu and obtein 25-30° C lower temp but for the cpu and nordbrige. but I want to do that with my vcard too. my geforce after cooper mod made 10°C lower. I hope posten here I hope that sameone can't help me please. thx btw hawe can't I extract v-bios from my bios.

 

Hello im trying to trick my laptop to think that my gt 420m is 425m or higher, do you think changing the device id under the adv.info tab on nibitor can do the trick? anyone know the device id of an nvidia gt 425m?

 

Does anyone know what the minimum possible and maximum possible voltages are for any Geforce 7000 series is?

thanks
