Thanks for the clarification.

The issue I was referring to is AVR-54 in that same spec update. "System May \
Experience Inability to Boot or May Cease Operation" I didn't see a way a BIOS update \
could resolve that issue! But I'm really glad to read that my box doesn't use the LPC \
bus at all. That does immunize it from AVR-54. ;-)
