Question one: how do I disable write caching on IDE drives? I know the
setting is hw.ata.wc=0, but where do I put that? In loader.conf? This is
FreeBSD 4.10, btw.

Also, has any thought been given to making the default 0, like it is for
SCSI devices? I'm honestly surprised and disappointed that the default
is speed over data integrity.

Question two: is there any support for SMART in FreeBSD? I see that
atacontrol cap displays the status (supported and disabled), but I don't
know of any way to turn it on. Likewise, what about the other options
shown by atacontrol cap?
