The problem can bite before the kernel has been loaded. Your BIOS should have an option to disable "IDE readhead" or similar, and this is the correct place to turn it off. > In any event, if my intution is correct here, I can't get FreeBSD running > until the read-aheads are disabled.

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.
