In other words, it is an computer inside of computer.
in fact it seems to sort of change the whole firmware padagrim. we have
main pc bios
PCI video : video bios
super io : standalone firmware
some pci card : pci bios.
what's significant here is that the superio is compiled with the super
IO's cpu as target rather than main cpu being the compilation target.
As time go on I expect there to be more subcompoents go like this.
The very fact alone that the compilation target is differnet suggest it
being removed from pc linuxbios main to large degree.
who actually did go over that 1000 page pdf.
