Parent article: Garrett: Rebooting
I don't really get the conclusion of the article:
"And, shockingly, it turns out that on most systems the ACPI reboot vector points at 0xcf9 in system IO space. Even though most implementations nominally require two different values be written, it seems that this isn't a strict requirement and the ACPI method works."
I don't understand what Matthew means here. How does this relate to the "gaps" between writes, and how does it make reboots work better?
I've had a couple of cold ones so my brain might not be functioning at peak performance right now. Still, I'd appreciate an elaboration. :-)
