Hi Andriy,
Thanks for the very detailed emails. It was great I could help.
I set Delivery Mode in the redirection table to the HyperTransport defined NMI message type, 0_011, and it worked!
Great, so there is a bug! Do you have some USB image I can try on more recent AMD system (with Hudson chipset). Or we can try to report this to AMD, but I have read somewhere that the new chipsets are done by Asmedia.
Thanks Rudolf
