Maybe the 0xCF9 port is defined for NVidia, SiS and Several others

Of course IMO it is not a generic solution for reboot.
At the same time the value written to the 0xCF9 I/O port should not be a
fixed value. Maybe it varies on different vendors/chipset. Even the
value will vary on the boxes from different BIOS vendors although the
boxes are based on the same chipset.
And the value should be provided by BIOS. If BIOS doesn't provide
the above info, it is not safe to use them.
We all agree that we should try to get the ACPI stuff to work as the
first instance. **THAT IS ALL THE HELP WE WILL GET FROM THE BIOS**.
Now, it isn't working. Now what do you do?
In short, unless you have anything concrete to add to this discussion,
please stop pontificating.
