Tony, That worked for the vfs.vmiodirenable, which can be enabled at anytime. However, for the "hw.ata.wc", I get an error for sysctl saying that it is read-only. According to the FBSD Handbook, it must be turned on before filesystems are mounted. The file /etc/sysctl.conf is executed right before you go into multiuser mode, which I think it too late and that probably why I'm getting that error. There are some kernel variables that are being set (although they are commented out) in /boot/defaults/loader.conf. I added my stuff in there, but like I said, it seems to be ignored.
