The SMBus specification describes the data protocols, device addresses, and electrical requirements that are superimposed on the I2C bus specification. The SMBus is used to physically transport commands and information between the Smart Battery, SMBus Host, Smart Battery Charger, and other SMBus Devices. This item is used to enable/disable System Mangement Bus controller. ► Debug Code Control This item allows you to select debug code control mode. Select "LPC", you can use onboard seven segment LED; Select "PCI", you must insert debug card into PCI slot. ► SLP_S4# Min. Assertion Width SLP_S4# is a signal for power plane control. This signal shuts off power to all non-critical systems when in the S4 (Suspend to Disk) or S5 (Soft Off) state. This setting indicates the minimum assertion width of the SLP_S4# signal to ensure that the DRAMs have been safely power-cycled. Setting values are: [4 to 5 seconds], [3 to 4 seconds], [2 to 3 seconds], [1 to 2 seconds]. ► PCIE Ports Configuration PCIE Port 0/1/2/3/4 This option is used to enable or disable the PCI Express port. Setting to [Auto] allows the system to detect the PCI Express devices automatically. If detected, the PCI Express Port is enabled, or else the PCI Express Port is disabled. 36
