How to flash bios from an Nvidia Geforce 8600M GT card. Help.

[workas21]

Hola a todos por favor necesito ayuda para flashear la bios de la tarjeta de video 8600M GT. Tengo un laptop acer aspire 7720G con windows 10 y sistema operativo de 67 bits con 4 de ram, la tarjeta de este pc se dañó, y compre una igual, como la que venia en el pc, de las siguientes características. Marca de GPU NVIDIA, Modelo de tarjeta 8600M GT, Tipo memoria DDR2, Tamaño de la memoria 512 MB. Pero el tema esta en que esta tarjeta estuvo montada en un pc ASUS.

Al encender el pc me da el siguiente error: estructura MXM no encontrada o inválida. Reflash MXM ROM! con un pitido durante 30 segundos.
He investigado ha cerca de este problema y he encontrado la versión adecuada para mi pc y también tres maneras de flashear la rom de la tarjeta grafica pero no me funcionan.
El primer intento lo hice con la ultima versión de Nvflash la 5. 715.0 y tengo este resultado.
​

El segundo intento lo hice con la versión 5.287.0 Joe dirt y tengo este resultado.

El tercer intento con la versión 5.590.0 tengo el siguiente resultado.

De ante mano gracias por su ayuda.

Hello everyone please I need help to flash the 8600M GT video card bios. I have an acer aspire 7720G laptop with windows 10 and a 67-bit operating system with 4 ram, the card of this pc was damaged, and I bought the same one, like the one that came in the pc, with the following characteristics. GPU brand NVIDIA, Card model 8600M GT, Memory type DDR2, Memory size 512 MB. But the issue is that this card was mounted on an ASUS pc.

When I turn on the pc it gives me the following error: MXM structure not found or invalid. Reflash MXM ROM! with a beep for 30 seconds.
I have researched this problem and have found the right version for my pc and also three ways to flash the graphics card rom but they don't work for me.
The first attempt I did with the latest version of Nvflash version 5. 715.0 and I have this result.

The second attempt I did with version 5.287.0 Joe dirt and I have this result.

The third attempt with version 5.590.0 I have the following result.

Thank you in advance for your help.

You seems to be flashing mobile GPU which is usually a bad idea since the video BIOS is embedded in the main BIOS. You can try to re-flash the laptop BIOS with latest version.

If you desire to ignore my warning, use old version of modded NvFlash, maybe 5.287, with the command line -5 -6 -7 filename.rom

If you replaced GPU with one from another laptop, try to flash the video BIOS where you taken the chip from:

Parece que está flasheando la GPU móvil, lo que generalmente es una mala idea, ya que el BIOS de video está integrado en el BIOS principal. Puede intentar volver a actualizar el BIOS de la computadora portátil con la última versión.

Si desea ignorar mi advertencia, use la versión anterior de NvFlash modificado, tal vez 5.287, con la línea de comando -5-6-7 filename.rom

Si reemplazó la GPU con una de otra computadora portátil, intente actualizar la BIOS de video de donde tomó el chip:

Hello friend, thanks for replying, I have followed your steps to the letter but I have the same error board ID mismatch!

After many hours of testing and researching on the internet I found the solution.
I used Nvflash version 5.134.01 and with the following commands:
-- protectoff
-4 -5 -6 name.rom

I leave this note in case anyone ever finds themselves in the same situation.

Thank you and regards.
