Abstract
A method and apparatus are disclosed for conditionally enabling/disabling PCI power management in a computer-based system employing a central resource and an operating system. Non-CLKRUN# compatible PCI devices in the system are identified and whether or not the non-CLKRUN# compatible PCI devices are enabled is determined. The CLKRUN# support capability of the central resource, if available, is enabled or disabled based on, at least in part, the established status of the non-CLKRUN# compatible PCI devices. If enabled, PCI power management is provided by the CLKRUN# support capability according to the PCI CLKRUN# protocol for all CLKRUN# compatible PCI devices present in the computer-based system.
