Intel®Server Board S1200BT TPS Functional Architecture 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 Dual Monitor Video Enabled Disabled Enabled Disabled 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. 3.7.2 Video for Intel® 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.
