FreeBSD has a form of "generic AHCI" support, where for systems which indicate AHCI is available but has no direct AHCI chipset driver, will fall back to using a generic AHCI implementation that should work with most all AHCI implementations. I would say what you're seeing is good. AHCI == good. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
