NVIDIA VGA BIOS Modification/Flash/Restore Guide
I give up driver level oveclocking and decide do BIOS level overclock using BIOS Flash .My Guide will show you how to modify your Nvidia video card BIOS and flashing it. This guide also tells you how to backup/restore your original BIOS .
Quote:
DISCLAIMER:
I test my guide with following desktop and Laptop cards
Laptops =Aspire 5920/ASUS C90
Desktops =ASUS 8800GTS/MSI 7600GT
So I can confirm my guide works and trouble free.
But .......
I am in no way responsible ,you do this at your own risk.

SUPPORTED CARDS:
You can use this guide to flash any GeForce Go 7xxx/8xxxM/9xxxM Card(Only MXM Type Cards) or Desktop GeForce 7xxx/8xxx/9xxx/GTX 2xx VGA Card with dedicated VGA BIOS
ASUS VX2S, G1S, G2S OWNERS PLEASE READ EXCLUSIVE ASUS V-BIOS MODDING GUIDE @ READ BEFORE FLASH YOUR CARD SECTION
|
YOU WILL NEED FOLLOWING THINGS TO FLASH YOUR VGA BIOS
1. USB Flash Drive
2. HP Bootable Flash Disk Maker or any software that can make bootable flash Drive
2. Rivatuner or ATITool(To do a driver level overclock before the BIOS Flash)
4. NiBiTor(To change bios values)
5. NVflash utility (To Backup/Flash your Nvidia VGA BIOS)
THINGS YOU NEED TO DO BEFORE THE BIOS FLASH
# Clean Install stable driver
# Install RivaTuner or ATITool
# Do driver level overclock using RivaTuner or ATITool
# After set overclocking levels as you wish using Rivatuner or ATITool : Test them to make sure card is stable.
Run 3DMark06 Tests.Repeat each test 16 times or more(select SM 2.0 & Sm 3.0 tests only)
Additionally you can try some GPU power hungry games (Eg:FEAR /SCDA/COD2)
# 3DMark06 tests are very important!!! please do it.
# Remember to monitor your VGA temperature while you are running 3DMark06 tests.
# FLASH YOUR VGA BIOS ONLY If 3DMark06 works perfectly.
# Lower your clock speeds if you got BSODs /ERRORs or ARTEFACTS
HOW TO BACKUP ORIGINAL VGA BIOS
# First make bootable Flash Drive and insert(copy) Nvflash files into it
# Restart your system and Set computer to boot from USB Flash Drive in BIOS
# After the system boot from USB Flash Drive
Type "nvflash[space]-b[space]OLDBIOS.ROM
(Eg= a:nvflash -b OLDBIOS.ROM)
# Press enter key
That command will save your original VGA bios on USB Flash Drive as a OLDBIOS.ROM
You can use that copy to flash back to original state if something goes wrong.
# Done. press ctrl+Alt+Del and restart your system into Windows
HOW TO MODIFY YOUR ORIGINAL VGA BIOS
# Copy your original VGA BIOS into Nibitor folder from USB Flash Drive
(Do not cut & paste .You need to keep original VGA BIOS copy on your Flash Drive until you successfully flash your card)
# Run NiBiTor and open OLDBIOS.ROM from it
# Modify 3D values(Core/Shader/Memory)
# Make sure to enter tested values using driver level overclock.
# Do not forget to reset all the driver level overclock settings to stock values
# GeForce 7xxx card owners can forget shader clock modify part
# You can Modify Voltage values(Strongly recommended only for Desktop VGA cards)
# Save modified VGA BIOS copy as a NEWBIOS.ROM
HOW TO FLASH YOUR ORIGINAL VGA BIOS
# Copy NEWBIOS.ROM into bootable Pen Drive
# Make sure OLDBIOS.ROM and NEWBIOS.ROM both copies available on your Flash Drive
# Restart your system and Set computer to boot from USB Flash Drive in BIOS
# After the system boot from USB Flash Drive
Type "nvflash[space]NEWBIOS.ROM
(Eg= a:nvflash NEWBIOS.ROM)
# Press Enter key
That command will flash your VGA BIOS and press "y" key or press Enter key when program ask your
confirmation
# Done.press ctrl+Alt+Del and restart your system into Windows
FIRST THING YOU NEED TO DO AFTER THE SUCCESSFUL VGA BIOS FLASH
# Run 3DMark06 tests again and repeat 16 times or more to make sure your VGA is stable after the BIOS flash.
WHAT YOU CAN DO IF VGA CARD IS UNSTABLE OR IF YOU GOT BSOD
(BLANK DEAD SCREEN) AFTER THE BIOS FLASH
FOLLOW THESE STEPS IF YOUR VGA BEHAVES STRANGELY
Your Simple solution is restore your original VGA BIOS again or Modify your 3D clocks to lower values .
# Restart your system and Set computer to boot from USB Pen Drive in BIOS
# After the system boot from USB Flash Drive
Type "nvflash[space]OLDBIOS.ROM
(Eg:a: nvflash OLDBIOS.ROM)
# Press Enter key
That command will flash your VGA BIOS to it's original state and Press "y" key or press Enter key
when program ask your confirmation
# Done.press ctrl+Alt+Del and restart your system into Windows
FOLLOW THEASE STEPS IF GOT BLANK (Dead Screen) AFTER THE VGA BIOS FLASH
Your only available option is boot blindly from the Flash Drive (That's why I told you to Set computer to boot from USB Flash Drive in BIOS)
# After the system boot from USB Flash Drive (Oh...sorry you can't see anything...so wait 1-2 min after you restart your system blindly)
Type "nvflash[space]OLDBIOS.ROM blindly
(Eg:a: nvflash OLDBIOS.ROM)
# Wait 2-3 second and Press Enter key blindly
That command will flash your VGA BIOS to it's original state and Press "y" key or press Enter key
# wait 10-20 second
# Done.press ctrl+Alt+Del and restart your system into Windows

FAQ:
GENARAL QUESTIONS:
Quote:
Can I use a mass storage external USB disk instead of the USB pen(Flash Drive)
No you can't
|
Quote:
what's the best clock speed for my card?
Every card have unique overclock level,so find it your self using Rivatuner or ATITool
|
Quote:
I got low score compared to others who have same clock speeds
Everything depend on your system spec and the way way you tweak your system.
BTW some users forget to increase shader clocks(Not valid for GF 7XXX Users)
|
Quote:
I seem to be having an issue...when i to try to test with 3dmarks05 after the driver level overclock,i get the error : "IDireect3DDevice9::Present failed: Device lost (D3DER_DEVICELOST)
Those kind of error shown if card is overclock too much.Lower your clock speeds and try again
|
Quote:
I have an ASUS G1Sn w/ a 9500M GS. I heard you can flash any GPU with the VGA BIOS of any other GPU's VGA BIOS of the same chipset: Is this true? (Eg: 9500M GS to 9650M GT just because both are based on G94 core)
No you can't do that & don't try to do it.It will may damage your VGA

INTEGRATED BIOS QUESTIONS(FOR LAPTOP USERS ONLY)
Quote:
I want to flash my 8600gt in a dell vostro 1500. But after I typed nvflash new.rom to flash the card i ever get this:
Warning: Firmware image Subsystem ID(1028.01F1) does not match adapter PCI Subsystem ID(1028.0228)
This can happen if vga bios integrated into your system bios .Integrated BIOS not work 100% correctly
Make sure you have mxm type vga card.BTW you can force nvFlash utility to flash your v-bios,but not recommended
|
Quote:
When I saved my stock bios,nvflash said that the version was unavailable, and the resulting file which it named OLDBIOS.ROM is
0 bytes. When I try and open the bios with nibitor I get an error message and it will not open.
# Make sure your vga card is MXM type & have dedicated vga bios
# Usb pen drive have free memory space to save the bios file(B'coz your flash drive act like a floppy & only few space available)

Re: Aspire 5920: VGA Bios modification/flash/restore guide
Nice and detailed guide! The HUGE red letters were clear and straight to the point. 
I've never really overclock before so please excuse these stupid questions:
1. For overclocking, is possible to just copy your settings without doing any testing since the system configuration is very similar?
2.If so, can you post your settings with Rivertuner? |

For Q 1-
It's possible,But I'm recommend you to do it with your BIOS  . You can send your original VGA BIOS to me ...then i can modify it and send it back to you.
For Q 2-
Wait for it  |
