摘要： Systems and methods for providing instant-on functionality on an embedded controller are disclosed. A method of providing instant-on functionality on a controller comprises an initial state, an intermediate state and a final state. The initial state comprises installing a first responder code, enabling the first responder code and enabling a timer interrupt service routine. The intermediate state comprises registering the first responder code as a timer interrupt service routine. The timer interrupt service routine initiates periodic processing. The final state comprises registering a steady-state interrupt service routine.

摘要： An auxiliary power control system for enabling a software command that a management controller sends to the power supply to shut down auxiliary power. Such a power control system enables an AC cycle without needing to physically remove an AC power cord and provides additional power savings when a system is not in use. In certain embodiments, the auxiliary power control system includes a paradigm of a main power state, an auxiliary power state and a sub-auxiliary state. In this system many of the power states and wake vents apply to the auxiliary power state in addition to the main power state.

摘要： An information handling system has the capability of matching UART baud rates and other serial data parameters between a system UART and baseboard management controller (BMC) UART used for serial-over-LAN (SOL) access to the information handling system via an Ethernet connection, either locally or remotely by a user, administrator, maintenance technician, etc. The BMC may snoop set-up data sent to the control register(s) of the system UART, look up a corresponding baud rate from a baud rate table of the BMC and set the BMC UART to match the system UART baud rate and other serial data parameters so that SOL access to the information handling system is available no matter what baud rate and/or serial data parameters an application may have programmed the system UART configuration registers. The BMC may snoop system UART data over a simple data bus such a low pin count (LPC) bus.

摘要： An information handling system receives management information from a network, such as IPMI information, with plural network interface cards of the information handling system in a teaming configuration. Upon detecting management information, a network interface card issues an SMBus alert to a management processor of the information handling system. A team module running on the management processor reads the status of the network interfaces to identify the network interface associated with the alert and reads the management information from the network interface. Management information sent to the network is sent through a predetermined one of the network interfaces to ensure that, if teaming gets deactivated at the switch, there will not be multiple NICs with the same BMC MAC address transmitting to the switch.

摘要： An application programming interface (API) enables a telephone to utilize the hardware resources of a computer that is connected to the telephone in a master/slave relationship that causes the computer to function in the manner of a peripheral to the telephone. Specifically, the telephone attached to the computer can utilize the relatively large memory capacity of the attached computer to store excess telephone-specific data and can utilize the relatively high sophistication of the processing capability of the connected computer to perform intensive data processing operations. The API allows the functionality of the telephone to be extended without requiring a telephony-equipped computer.
