You would think there would be a simple way to check this.  The best I've come up with is to either:

Change the BIOS back to IDE.  If the system doesn't boot, then AHCI is enabled and working.  Then change BIOS back to AHCI.

You could also download AS-SSD Benchmark software (it is in German, but can still be used in the way you need here)

Run AS-SSD Benchmark, then check your driver in the upper corner of the program.  It should be msahci.sys, or possibly iastor, either means you are in AHCI mode.
This link gives some more info on that:

Hope that helps.
