Maybe you already know this, but I would not expect the superio to be involved very much in the dualbios mechanism - at most an IO pin would be used for the handshake with the patented timer.
Still I would like to get the spec.
Yes, fair enough. :)
It may also depend on a particular motherboard, chip, etc. Perhaps the "patented timer" is implemented in Super I/O.
I doubt this since Gigabyte owns the patent for the dual bios invention, and ITE is unrelated to Gigabyte. The dual bios invention might *use* a timer within the superio though - that's possible.
At least, we see that some undocumented Super I/O register(s) are used to switch between the flash chips and some other related things.
IO pins and timer on the superio could certainly be used.
