Re: [flashrom] (update, update) Gigabyte GA-7ZXE v1.1

Oops, my bad, I was pretty sure the VIA chip was the Southbridge but I
questioned my own logic when I saw it listed as a super i/o chip in
the manual:

Chipset: VT82C686B PCI Super-I/O Integrated Peripheral
        Controller (PSIPC)

There's a chip just under the tail of the AGP slot that might be the
super i/o chip... it's an
ICS 94236AF but this is listed as the clock generator...

So where is the super i/o chip usually located?

Heh. This chip is special. It is a south bridge AND a SuperI/O in one
package.

Datasheet: http://linux.kernel.free.fr/VT82C686B.pdf

I sent a superiotool patch for this to the list a few seconds ago. Note
that that patch in its current form may mess with floppy configuration
instead of detecting the SuperI/O. This is due to missing PCI support in
superiotool. Still, it would be very valuable if you could try this patch.

And to make it work, please run superiotool again after executing
setpci -d 1106:0686 85.b=02:02

You can get back the original state of the chipset with
setpci -d 1106:0686 85.b=00:02
