Abstract
A call from a user operating system (UOS) to BIOS to configure a connected device into a reduced energy consumption mode is routed through a virtual machine monitor (VMM). The VMM determines whether a service O.S. (SOS) is in need of the device and if so the VMM informs the UOS that the device has been configured as ordered, while allowing the SOS to complete its task with the device. If the SOS is not in need of the device, or at the completion of the SOS task with the device, the VMM passes the call to ACPI/BIOS to configure the device in the demanded energy consumption mode.
