The boot drives are plugged directly into the Motherboard's SATA ports, which I believe is powered by a ULi M1689 chipset. I also have a Supermicro AOC-SAT2-MV8 PCI-X HBA card which has a Hercules-2 Rev. C0 SATA host controller built in. I've added ahci_load="YES" in my /boot/loader.conf and I can see that ahci.ko was loaded using klstat, but I do not see any drives appearing that use the ahci module. All d rives are labeled /dev/ad* instead of /dev/ada* and hotswap doesn't work properly. Running dmesg |grep -i ahci comes back empty. I can't say about ULi SATA - I haven't tried any of them. Make sure that you have AHCI mode enabled in BIOS. ahci(4) driver should attach to any hardware that reporting AHCI compatibility via PCI class/subclass. Supermicro AOC-SAT2-MV8 - is not AHCI compatible. New driver for it named mvs(4). It was merged to 8-STABLE just a few weeks ago. You may update your system and try it. -- Alexander Motin
