This field is used to pass data between the OS and the SMI handler. Basically, this is a scratchpad
register and is not affected by any other register or function (other than a PCI reset).
This field is used to pass an APM command between the OS and the SMI handler. Writes to this
port not only store data in the APMC register, but also generates an SMI# when the APMC_EN bit is
set.
