Intel S1200BT Technical Product Specification - Page 45

Intel® Server Board S1200BT TPS Functional Architecture  In the single mode (dual monitor video = disabled), the on-board video controller is disabled when an add-in video card is detected.  In single mode, the onboard video controller is disabled when an add-in video card is detected.  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 11. 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 and 66 MHz PCI Master/Slave interface.  33 MHz and 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) Revision 2.0 33 Intel order number G13326-004
