Nice tool, but it cannot find one of my cards. I have two 5830s installed, both are being detected by Linux and ATI drivers:
I have one mobo that does this with it's 2 x 5830's. One boot only card 2 and only video on card 2 (even boot up bios screen). One or two reboots and video moves to card 1 where it should be and Diablo can then use both cards. Seems that something gets messed up on a soft reset. Power off for 3 mins and it always comes up right.
I have another very similar machine, same OS, same drivers, same config files, both i7-87x 1156 sockets, different mobos and it never does this. The one that gives me the problem is a MSI H55-GD65 (H55) the one that doesn't is a BioStar T5 XE (P55) mobo.
