You would think so wouldn't you? However, I believe it's all done in
software via System Management Mode.
I once worked on an OS which we ran on PC hardware for development

millisecond or more, making it impossible for a modern PC to even keep a
bog standard 115kbit/sec serial port UART from underflowing. :-(
