   Not sure if I can use COMPAT_4X libraries coz the recomendation is to
   use COMPAT_3X libraries for my application. I have read up lots of
   forum and discussion about the SATA but still have no any solution.
   Would you mind to send me any guide in steps to install SATA to
   freebsd v4.8. How can I configure this so my HDD can be detected? How
   can I go in to the kernel and run the command?

   To be honest, I'm still new to FreeBSD but I need to support FreeBSD
   to my customer. Hope anyone can help in this regards.

   Rgds, Ann
