So i'm thinking about flashing my 8800M GTX Vbios to 9800M GT. Reason is that my HDMI port isn't getting detected on my 8800M GTX. Read earlier thread http://forum.notebookreview.com/sager-clevo/541456-hdmi-no-signal-hdtv-2.html.
So i'm wondering if anyone could tell me how to go about it and if anyone got a Vbios for Clevo 9800M GT. My model is Clevo m570tu.

Flashing different vBIOS usually causes HDMI problems, not fixes them.
-
Except that the 8800M GTX came out before clevo had HDMI, therefore its vbios doesn't support it whereas I think the 9800M GT vbios (same physical card) might support HDMI.
-
Here is a 9800m GT vBIOS that works with M570RU/TU.
Hope it will help!

So did it fix your HDMI problem?
-
I got it all set but when i try to flash I get wrong Device ID. How do I change the device ID? Should i change the device ID on my card or the Device ID on the 98gt.rom?
-
Hello,
this is normal.
just type
nvflash -4 -5 -6 98gt.rom
and then say "yes" or "y".
Even if you modify your OWN Bios and flash that it will say "wrong device ID". -

I'm gone set back the device ID on the 98gt.rom. :X -
Ok it worked !
thanks again Tirenz! So now I have to use 9800M GT Drivers?
-
Yes, but I think the driver for the 9800m GT will extract himself from the 8800m GTX driver. Just see what I mean at next boot
.
-
Now to check if the hdmi is working !
-
Yesss! It works thanks a lot to everyone!!
-
Glad it worked!
Cheers! -
Will there be any gain or loss in speed with the bios shift?
-
I don't believe anyone had any noticeable difference
