I installed Leopard and then installed Windows XP Pro using boot camp assistant. All my drivers seemed to install correctly. I went to device manager in XP Pro there is the yellow question mark by SM Bus Controller. Anyone have any idea what this is and how to get the driver for this. I am running a this on a MBP 2.4 GHZ "Santa Rosa" platform.

Same thing happened to me on my Alu 24" when I installed the beta 1.4 drivers. I fixed it by manually installing the driver: insert the driver disk, then select the device in Device Manager and choose "update driver" (or perhaps "reinstall driver"--I'm working from memory here). Be sure to tell it to look on the CD you've inserted.
