Energy Star PCI Device

Q: I'm developing a PCI device for Mac OS X and I want it to be an energy star device. Can you point me to some documentation and/or supply me with any sample code or suggestions.

A: There is a document called I/O Kit Fundamentals at this URL:

http://developer.apple.com/documentation/Darwin/kernel.html

Chapter 10 Managing Power and Device Removal has the information you seek along with code examples.

Also remember that the PCI Specification requires all PCI devices to be operational from D.C. to 66 MHz. This means your device must be capable of the case where the PCI clock is turned off and then back on at some arbitrary time.
