Power Management Setup
Options related to power management can be altered through the following:

3.5.5 PCI Express PM Function

PCI Express components are permitted to wakeup the system using a wakeup mechanism
followed by a power management event (PME) Message. PCI Express systems may provide
the optional auxiliary power supply (Vaux) needed for wakeup operation from states where the
main power supplies are off. PCI Express-PM extends beyond the PME mechanism defined in
conventional PCI-PM as PCI Express PME Messages include the Requestor ID of the
requesting agent. These PME Messages are in-band TLPs routed from the requesting device
towards the Root Complex.
PCI Express PME
This option performs the same function as Wake-Up by PCI card, but is for PCI-Express cards.
