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?
