Just had a nightmare as when I installed 10.1, it disabled my 2nd 5870 and Crossfire disappeared!!
Even after uninstalling and re installing 9.12 still no Xfire!!
In the end I had to repeat these instructions below:
"It is a driver issue of sorts for me, this ended up being a residual driver install, where the ccc of 9.12 would not remove itself.
In the end, i had to uninstall drivers, use driver sweeper, remove the second card from mobo.
Boot into windows, install drivers for the first card, and then shut down.
Install second card into mobo (no crossfire bridges attached), boot into windows, install drivers again, then shut down.
Then attach crossfire bridges, boot into windows, enable crossfirex, then reboot windows. "
Did install 10.1 each install from above and now Xfire is back!! Phew!!
