The above doc is for the AMD-768 Peripheral Bus Controller. Luckly the pre-production Thunder K7 mobos had AMD-766's in them. I don't know if Tyan switched to the 768 in later production. http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/23615.pdf In HTML format: http://www.google.com/search?q=cache:eipmgE1E_f4C:www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/23615.pdf+amd+766+revision+guide&hl=en&ie=UTF-8 Is the revision guide for the AMD-766 south bridge. There are 2 USB nits, but nothing serious like for the AMD-768 rev B1. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
