WAKE/SMI#. This command wakes the system if it is not already awake. If
system is already awake, an SMI# is generated.
NOTE: The SMB_WAK_STS bit will be set by this command, even if the system is
Unconditional Powerdown. This command sets the PWRBTNOR_STS bit, and
has the same effect as the Powerbutton Override occurring.
HARD RESET WITHOUT CYCLING: This command causes a hard reset of the
system (does not include cycling of the power supply). This is equivalent to a write
to the CF9h register with bits 2:1 set to 1, but bit 3 set to 0.

SMLINK_SLV_SMI_STS bit may get set but not serviced before the system
goes to sleep. Once the system returns to S0, the SMI associated with this
