[aduy]

i want to flash the 1.03v bios for my 485m in windows 7 64bit, but i can't get nvflash or nibitor to work. can some one walk me through how to do this. any help would be great, thanks.

Use this nvflash version: nvflash windows 5.100.0.1 it'll work with your card.

Be sure to run "nvflash --save backup.rom" just to be safe.

Usage:

Primary Commands:

Update firmware:            nvflash [options] 
Save firmware to file:      nvflash [options] --save 
Compare adapter firmware:   nvflash [options] --compare 
Update TV data:             nvflash [options] --tv 
Display version:            nvflash [options] --version []
Display firmware bytes:     nvflash [options] --display [bytes]
Check for supported EEPROM: nvflash [options] --check
Write protect EEPROM:       nvflash [options] --protecton
Remove write protect:       nvflash [options] --protectoff
Change soft straps:         nvflash [options] --straps=
Set IEEE 1394 GUID:         nvflash [options] --guid=
Set IEEE 1394 GUID source:  nvflash [options] --guidsource=
List adapters:              nvflash [options] --list

                          This allows flashing a corrupted or erased EEPROM.  
                          Note: Make sure there is a physical EEPROM present

Use a single dash ("-") to use the single letter version of a command.
Use a double dash ("--") to use the longer descriptive version of a command.
Use equals ("=") to specify parameters, with separating commas (",").

Excellent good sir + rep, but im not really sure how to use it. any help. i tried to type in but every time i hit a key it just displays more commands, and then closes

Are you first booting from a device with nVFlash on it?

[aduy]

honestly i searched google for 10 minutes about how to use it and found nothing, so i need a step by step instruction list, because i don't understand at all what to do. from what you said, i guess you stick nvflash on a bootable disk, and possibly some other files, like the system files included, and the bios that i want to flash. then i boot it and use the commands to do the flash.

That's pretty much it.

Here's an extensive guide on vBIOS flashing:

well if its this simple can someone post step by step instructions to do it, cause im not really comfortable, doing this on the fly, i need some instructions, from someone who has done this before.

The version I linked is for Windows 32/64, it does NOT run from dos, you use the Windows command prompt.

To flash go to the nvflash directory in command prompt and type "nvflash biosfilename.rom" without quotes and with the actual name of your bios file.

alternatively you can make a batch file for it, just open a text editor and type in:
nvfash.exe vbios.rom

Then save this as flash.bat and put it in the same directory as nvflash, then name your bios file vbios.rom and double click the batch, it'll prompt for elevated privileges and flash the bios in a command prompt Window, if you want to make a batch file for backing up put in a text editor:
nvflash.exe --save backup.rom

save as backup.bat, hope this helps.

i did the second way and it beeped...?

What is the actual name of your bios? I doubt it is vbios.rom ?

I prefer putting nvflash and the bios onto a bootable usb flash disk and boot from it.
