Hi All
I've spent some time tracking where packets come from. I have traced it back to a jump table that is never called from the XBE. This is probably a memory mapped interupt list and I have a feeling that its the MCPX chip (southbridge) that triggers the interupt. If its not that then its in the bios. I'll fire up my linux xbox and do some multicast tests on there to see what happens. Is there anyone with more hardware hacking or bios experience out there who could put a bit more light onto it or do some tests?
Thanks
JC
