Am I using IDE or AHCI?

I recently installed an SSD in my laptop, but according to what I've read AHCI mode is preferable to IDE mode for SATA drives, something that is set in the computer's BIOS. However, I don't have any such option in my BIOS. Is there a way to check which SATA mode I am using from inside the OS?

I own a Sony Vaio S13 running Ubuntu 12.04.1.
