I believe so, yes. I have several SATA systems running FreeBSD, as well as some ATA. Only difference is the numerical start- ad0 as opposed to ad4, but I believe that is mainboard bios dependent.

Subject: Onboard SATA Controller of Intel DH55HC Motherboard (FreeBSD 7.3
&
  FreeBSD 8.1)

Hello FreeBSD people all over the world,

There is an onboard Intel SATA controller on Intel DH55HC motherboard. I
have tried FreeBSD version 7.3 and 8.1 on this motherboard, it recognizes
the SATA controller but recognizes the hard disk as IDE devices. How can
this happen?

I did everything to prevent the FreeBSD kernel from recognizing the hard
drives as IDE. I turned off all IDE emulation options in the BIOS.

How can I fix that?
what are you -expecting- to see?   ATA drives, either PATA or SATA _are_
IDE interface.  the boot messages show they're being regocnises as SATA,
at 3 gigabit/sec.   Everything looks right to me. :)
