The system uses the Intel H57 (Ibex) chipset, which is documented here: http://www.intel.com/Products/Desktop/Chipsets/H57/h57-overview.htm The official datasheet is here (~4.4MBytes): http://www.intel.com/Assets/PDF/datasheet/322169.pdf Which does state AHCI is available, however Intel is known for making separate SKUs (revisions/models with different tweaks to the chips) that support different features. Table 1.3 on the PDF outlines what the H57 is capable of: Intel 5 Series Chipset SKUs (Desktop) SKU Name AHCI RAID 0/1/5/10 Support ----------------------------------------- Q57 Yes Yes H57 Yes Yes <==== H55 Yes No P55 Yes Yes ----------------------------------------- Intel 3400 Series Chipset SKUs (Server) SKU Name AHCI RAID 0/1/5/10 Support ----------------------------------------- 3400 No No 3420 Yes Yes 3450 Yes Yes ----------------------------------------- Further within the documentation, it states that for eSATA hot-plug to work, AHCI has to be enabled/in use. That's about all I can discern from the PDF without getting into technical specifics. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
