Request for clarification on the BIOS of 5578

Hi,

      I have just bought a Dell Inspiron Laptop 5578. I would like to know whether the BIOS supports AHCI or is it a "UEFI" one? And how do I check that?

AHCI is one operating mode for the hard drive(s).  UEFI is a firmware technology that replaces the legacy BIOS.  These systems support both AHCI and UEFI.
