While it's building I decide to re-read the recent thread http://docs.freebsd.org/cgi/mid.cgi?6.0.3.0.0.20040226131930.10513908 I'd discounted this as I wasn't seeing the EEPROM message. Sure enough, moving the em0 card seems to fix the problem. I'll reply to self again once I confirm the conflicting item ;) -- i j hart ICT Technician Cardinal Newman Catholic School & Community College
