I got two 5800 series GPU installed on single machine. But the calDeviceGetCount API always return 1, and the calDeviceOpen(&dev, 1) API always fail. Is there any special requirement to use the secondary GPU?

My operating system is windows xp sp3. The SDK is atistream-1.4.0_beta-winxp32.exe and the driver is 9-12_xp32_dd.exe. No display is attached to any of the card.
