Is it Ok to flash BIOS like this

Hi, Just got these instructions from MSI to flash my GTX 970. Is this method safe to use?
Is there a better way to do it. Many thanks for any help.


1.Download the attached rar file and extract it on your disk ;
2.Open a command prompt in Windows (shortcut key: windows+R) go to the folder(cd filename);
3.Type: nvflash.exe NV316MH.186.rom -A -6
4.Press enter;
5.When it prompts you reboot, please type:reboot and press enter to reboot your systerm.

 

Well the command line itself (#3) does not look odd to me. -a shows all available adapters (cards that have the right hardware, as in all 970s in your system), -6 overrides not matching PCI subsystem ID (of your card, in case you'd be flashing somebody else's bios, as in a new one, not your own factory bios modified).


Use this as a reference:

edit: just as I noticed, you need to disable your device (970) in the device manage before flashing since Maxwell, iirc. Somebody else please correct me if wrong. Disable, flash bios, reboot.

 

Hi the BIOS is from MSI and I will have one card in the system at a time. This is the latest MSI BIOS as obtained from MSI today. Regards

 

You should be fine. Just disable the card in the device manager first, or flashing won't work properly. Use the command lines given to you by MSI.

 

Ok thank you very much.

 

The command should be a bit different IIRC. The last two bits should be before the nameofBIOS.rom

 

Thank you, did flash just as MSI said but did not see your post until just now but all is good in the world. It works! thank you any way. (I did disable device though just to be sure)

By the way this is the 84.04.36.00.F1 BIOS.

 

Good that it's not bricked I hope MSI's bios takes care of your issues.

 

you need joedirt's nvflash from overclock.net

nvflash --protectoff
nvflash --index=0 -6 yourbios.rom
y to confirm
nvflash --protecton
reboot

EDIT:
Just saw that you successfully flashed you bios. Glad it worked out!

 

Thank you all!

 

thank you
