3.4 I/O Sub-system
Intel
®
C200 Series PCH provides extensive I/O support.
3.4.1 Digital Media Interface (DMI)
Direct Media Interface (DMI) is the chip-to-chip connection between the processor and C202
chipset. This high-speed interface integrates advanced priority-based servicing allowing for
concurrent traffic and true isochronous transfer capabilities. Base functionality is completely
software-transparent, permitting current and legacy software to operate normally.
3.4.2 PCI Express Interface
The PCI-E configurations for each SKU are defined below:
 Intel
®
Server Board S1200BTL
One PCI-E x16 connector to be used as a x8 link, two PCI-E x8 connectors to be used as a
x4 link and one SAS module connector to be used as a x4 link connected to the PCI-E
ports of the processor. One PCI-E x8 connector to be used as x4 link connected to the PC-
E ports of PCH.
 Intel

Server Board S1200BTS
One PCI-E x16 connector to be used as x8 link, one PCI-E x8 connectors to be used as a
x8 link connected to the PCI-E ports of the processor. One PCI-E x8 connector to be used
as x4 link connected to the PCI-E ports of PCH.
There is one 32-bit, 33-MHz 5-V PCI slot, common on both SKUs.
Compatibility with the PCI addressing model is maintained to ensure all existing applications
and drivers operate unchanged.
The PCI Express* configuration uses standard mechanisms as defined in the PCI Plug-and-
Play specification. The initial recovered clock speed of 1.25 GHz results in 2.5 Gb/s each
direction, which provides a 250-MB/s communications channel in each direction (500 MB/s
total). This is close to twice the data rate of classic PCI. It is a fact that 8b/10b encoding is used
accounts for the 250 MB/s where quick calculations would imply 300 MB/s. The external
graphics ports support 5.0 GT/s speed as well. Operating at 5.0 GT/s results in twice as much
bandwidth per lane as compared to 2.5 GT/s operation.
When operating with two PCI Express* controllers, each controller can operate at either 2.5
GT/s or 5.0 GT/s. The PCI Express* architecture is specified in three layers: Transaction Layer,
Data Link Layer, and Physical Layer. The partitioning in the component is not necessarily along
these same boundaries.
3.4.3 Serial ATA Support
The Intel
®
C200 Series chipset has two integrated SATA host controllers that support
independent DMA operation on up to six ports and supports data transfer rates of up to 6.0
Gb/s on up to two ports (Port 0 and 1 Only on S1200BTL) while all ports support rates up to 3.0
Gb/s. The SATA controller contains two modes of operation – a legacy mode using I/O space,
