Intel® Server Board S1200BT TPS Functional Architecture
Revision 1.0
Intel order number G13326-003
In dual mode, the onboard video controller is enabled and is the primary video device.
The external video card is allocated resources and is considered the secondary
video device.
When KVM is enabled in iBMC FW, dual video is enabled.
Table 10. Dual Video Modes
Onboard video controller.
Warning: System video is completely disabled if
this option is disabled and an add-in video
adapter is not installed.
If enabled, both the onboard video controller
and an add-in video adapter are enabled for
system video. The onboard video controller
becomes the primary video device.

®
Server Board S1200BTS
SM712 is a video chip from Silicon Motion, Inc (SMI). It is one in SMI‘s LynxEM family. It is PCI
2.1 compliant with the standard PCI 33MHz & 66 MHz PCI Master/Slave interface.
33 MHz & 66 MHz PCI Master/Slave interface
PCI 2.1 compliant
Memory control is provided for the 4MB internal memory
Support 640x480, 800x600, 1024x768 resolution and up to 85Hz.
Dual Video mode is supported.
3.8 Network Interface Controller (NIC)
The Intel
®
Server Board S1200BT supports two network interfaces, One is provided from the
onboard Intel
®
82574L GbE PCI Express network controller; the other is the onboard Intel
®
82579 Gigabit Network controller.
3.8.1 Gigabit Ethernet Controller 82574L
The 82574 family (82574L and 82574IT) are single, compact, low-power components that offer
a fully-integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) port.
The 82574 uses the PCI Express* architecture and provides a single-port implementation in a
relatively small area so it can be used for server and client configurations as a LAN on
Motherboard (LOM) design.
External interfaces provided on the 82574:
PCIe Rev. 2.0 (2.5 GHz) x1
MDI (Copper) standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASETX,
and 10BASE-T applications (802.3, 802.3u, and 802.3ab)
NC-SI or SMBus connection to a Manageability Controller (MC)
EEE 1149.1 JTAG (note that BSDL testing is NOT supported)
3.8.2 Gigabit Ethernet PHY 82579
The 82579 is a single port Gigabit Ethernet Physical Layer Transceiver (PHY). It connects to
the Intel
®
C200 series Chipset‘s integrated Media Access Controller (MAC) through a dedicated
interconnect. The 82579 supports operation at 1000/100/10 Mb/s data rates. The PHY circuitry
