The Intel
complies with Revision 1.1 of the PCI Power Management
Specification.
This bit is set when the Intel
normally assert the PME# signal independent of the state of
the PME_En bit. Writing a ’1’ to this bit will clear it and cause
the internal PME to deassert when enabled. Writing a ’0’ has
no effect. This bit must be explicitly cleared by the operating
system each time the operating system is loaded.

The Intel
because it does not support the associated Data register.
A ’1’ enables the Intel
internal PME signal when PME_Status is 1. This bit must be
explicitly cleared by the operating system each time it is
initially loaded.
