Need Help to EFI Flash a Radeon HD 6870

[Washac]

Just in case I decide to EFI flash my new video card can anybody point me in the direction of a guide for complete noobs, I have a rough idea of what is required ?

I have Cindoris Zeus app.
The card to flash would be a - XFX Radeon HD 6870, HD-687A-ZDFC

Maybe also post the model of your card, in order for others to help you.

Card details added, sorry about that.

Very surprised nobody can help out with this so far

Look on netkas' forums, the way I did it involved doing it using terminal, none of the apps worked for me.

Also you need to flash in windows, mainly because OS X flashes didn't work either. This was 6+ months ago tho, so things might have changed.

Netkas has an XFX 6870 EFI ROM here: http://forum.netkas.org/index.php/topic,1085.msg6517.html#msg6517

Download that and follow instructions here to create your new ROM: http://forum.netkas.org/index.php/topic,1085.msg6487.html#msg6487

Or download romcreator and have it do it for you: http://forum.netkas.org/index.php/topic,1085.msg6648.html#msg6648

Flash with Zeus.

Thanks, I knew somebody would come up with the goods, I hope this is not too complicated.

So after installing the 6870 I can use Romecreator and then flash Zeus and jobs done, I assume that is correct ?

Theoretically, yes. Also, once flashed, the XFX 6870 only shows the apple boot screen in the lower DVI port, I believe, so if you're only using one of the other ports it might not be worth it.

OK, thanks for that bit of information

i believe zeus is outdated and you should use freya instead... found at groths.org

but frankly... there is no reason to flash a 6870... if you go to grorths you will also find a fix for the few issues that remain with the 6870 (steam and dvd player fixes etc). All you will get is a boot screen... and who needs a boot screen really? In there very few instances i do need a boot screen... i throw my old card back in... which has yet to happen since upgrading.

I think Zeus 2.3 was only one to flash SOME 6870s.

Flashing only helps cards used in 3,1 and later Mac Pros.

Flashing 6870 with 64-bit EFI does not mean anything for 32-bit EFI machines like MP 2006/2007. MP 3.1+ (Early 2008) have 64-bit EFI and they colud read 64-bit EFI from Radeon.

Here is what you're looking for. I flashed the same card a few months ago.
