Intel® Server Board S1200BT TPS Functional Architecture each device is treated as a master - and hardware assisted native command queuing. AHCI also provides usability enhancements such as Hot-Plug. AHCI requires appropriate software support (for example, an AHCI driver) and for some features, hardware support in the SATA device or additional platform hardware. 3.4.3.1 Intel® Matrix Storage Technology The Intel® C200 Series chipset provides support for Intel® Rapid Storage Technology 11.0, providing both AHCI (see above for details on AHCI) and integrated RAID functionality. The RAID capability provides high-performance RAID 0, 1, 5, and 10 functionality on up to 6 SATA ports of the PCH. Matrix RAID support is provided to allow multiple RAID levels to be combined on a single set of hard drives, such as RAID 0 and RAID 1 on two disks. Other RAID features include hot spare support, SMART alerting, and RAID 0 auto replace. Software components include an Option ROM for pre-boot configuration and boot functionality, a Microsoft Windows* compatible driver, and a user interface for configuration and management of the RAID capability of PCH. 3.4.4 Low Pin Count (LPC) Interface The Intel® C200 Series chipset implements an LPC Interface as described in the LPC 1.1 Specification. The Low Pin Count (LPC) bridge function of the C202 resides in PCI Device 31: Function 0. In addition to the LPC bridge interface function, D31:F0 contains other functional units including DMA, interrupt controllers, timers, power management, system management, GPIO, and RTC. 3.4.5 USB 2.0 Support On the Intel® C200 series PCH Chipset, the USB controller functionality is provided by the dual EHCI controllers with an interface for up to ten USB 2.0 ports. All ports are high-speed, full- speed, and low-speed capable.  Four external connectors are located on the back edge of the server board.  Two internal 2x5 headers (J1E1 and J1D1) are provided, each supporting two optional USB 2.0 ports.  One port on internal smart module connector (J1J2) on Intel® Server Board S1200BTL. 3.4.5.1 Native USB Support During the power-on self-test (POST), the BIOS initializes and configures the USB subsystem. The BIOS is capable of initializing and using the following types of USB devices.  USB Specification-compliant keyboards.  USB Specification-compliant mouse.  USB Specification-compliant storage devices that utilize bulk-only transport mechanism. USB devices are scanned to determine if they are required for booting. The BIOS supports USB 2.0 mode of operation, and as such supports USB 1.1 and USB 2.0 compliant devices and host controllers.
