First, I want to thank James and the other responders for help getting me squared away. Something that may be of specific use for others (James has covered the most relevant points...at blazing speed, what an asset to the community), is that the isci support in 8.3-R will now enable FreeBSD compatibility with most of the new Supermicro server platforms. And a new lesson was learned....first thing to try when sysinstall fails to recognize hardware is to re-scan devices. Never needed that across thousands of installs (dating to 2.2.8), and didn't even know it existed. Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---
