The problem can bite before the kernel has been loaded.

If I recall correctly, the ATA-2 spec says that drives should not default to green mode; you're probably going to have to check with the spec and add some special code to the 'wd' driver to recognise your drive and disable 'green mode'. > --Brett > > P.S. -- I do like FreeBSD's configuration and installation routines much > better than the ones that come with Caldera, by the way.
