To All CrossFire Users:Anyone Needed To Bios Flash to Enable CrossFire?

From the 'NVIDIA drivers Vs AMD drivers' thread found here:

Bhavv pointed out something I have never known about, or indeed ever had to do myself:

4870 crossfire - didn't work without a bios flash
5770 crossfire - gray screens of death without a bios flash

GTX 460 / 560 SLI - worked perfectly out of the box.

Skyrim - Zero day SLI support added as an SLI profile by Nvidia, AMD crossfire didn't work, produced negative scaling, AMD blamed Bethesda.

NVIDIA drivers support driver level FXAA, adaptive vsync, 3d vision and physx. Only one of those is an NVIDIA exclusive, AMD drivers still don't support the other 3.

And:

Dude Nvidia rolled out full SLI support profiles for Skyrim the day before it realeased, and it has been working flawlessly since.

Any system with crossfire ran skyrim at a 20 fps slideshow for several months after the game had launched.

Plenty of Nvidia issues with Skyrim ... Yea right, making things up as you tend to do.

I didn't even mention anything about scaling in my comparison, all the scaling in the world wouldn't matter the slightest if the multiple GPU setup simply doesn't work well in the latest games, or needs severe measures like bios flashing to get it working, which tends to be a recurring case with crossfire.

Also your 2 Gb memory on the 6970s was always worse and beaten in just about everything by 1280 Mb GTX 570s, even at 2560x1600 resolution.

ATI 6900 series - most useless and misleading GPUs ever released with 2 Gb vram. Worse in almost everything than 1.2 - 1.5 Gb on GTX 570 / 580.

As I said, has any CrossFire users past/present had to flash their bios, to get CrossFire to work?

Thanks in advance.

Thanks for the info folks, just thought I would find out from CrossFire users if there was any truth in the matter, but the answers given were what I was expecting tbh.
