Hard Disk parameters (caching/dma)
Linux uses hdparm to set these parameters, my question is: what tool uses BSD systems (FreeBSD/OpenBSD/NetBSD)? There is another thing which FreeBSD implements on their filesystems: softupdates. If I forgot to enable this option when I partitioned the disk, how could I enable it at a later time?

in freeBSD to enable the Soft Updates try:
# tunefs -n enable /filesystem

*tunefs - tune up an existing file system

I tried to check the similiars with hdparm in FreeBSD, NetBSD & OpenBSD but cant get and accurate answer for that.

Try to search in the man page hdparm for freebsd, openbsd and netbsd.
