 DragonFly BSD has supported AHCI with NCQ since 2.3 in 2009.Newer mainstream Linux kernels support AHCI natively, and FreeBSD fully supports AHCI since version 8.0.Windows Vista and Windows 7 also natively support AHCI, but their AHCI support (via the msahci service) must be manually enabled via registry editing if controller support was not present during their initial install.
