摘要： A network computer (12) receives instructions from a network manager (11), including a control interrupt instruction, a system management instruction, and a release instruction. A processor (16) associated with the network computer (12) executes the control interrupt instruction first to produce a control interrupt signal. This control interrupt signal causes an operating status controller (17) associated with the network computer (12) to disable local operational status control at the network computer. After local operational status control is disabled at the network computer (12), the processor (16) executes the system management instruction and performs a system management operation at the network computer. Finally, after the system management operation is completed, the processor (16) executes the release instruction to produce a release signal. The release signal causes the operational status controller (17) to enable local operational status control at the network computer (12).
摘要翻译：网络计算机（12）从网络管理器（11）接收包括控制中断指令，系统管理指令和释放指令的指令。与网络计算机（12）相关联的处理器（16）首先执行控制中断指令以产生控制中断信号。该控制中断信号使得与网络计算机（12）相关联的操作状态控制器（17）在网络计算机上禁用本地操作状态控制。在网络计算机（12）上禁用本地操作状态控制后，处理器（16）执行系统管理指令，并在网络计算机上执行系统管理操作。最后，在系统管理操作完成之后，处理器（16）执行释放指令以产生释放信号。释放信号使操作状态控制器（17）在网络计算机（12）上启用本地操作状态控制。

摘要： A system reset arrangement (12) resides alternately in an enabled condition or a disabled condition. When the system reset arrangement (12) is in the disabled condition, a switching input provided through a switch (11) does not effect a system reset. However, in the enabled condition, the switching input through the switch (11) causes system reset arrangement (12) to produce a reset output which resets the system. A reset disable arrangement (14) maintains the system reset arrangement (12) in the disabled condition in response to a disable input. When the disable input is removed, reset disable arrangement (14) maintains system reset arrangement (12) in the enabled condition. An interrupt output (15) develops an interrupt signal in response to the switching input. This interrupt signal prompts an interrupt controller (16) to issue a desired system management command to be processed by the system processor. This command may place the system in a standby mode and, in any event, removes the disable input, causing the reset disable arrangement (14) to maintain the system reset arrangement (12) in an enabled condition. Thus, activating the switch (11) while the computer is in a normal operational state causes the computer to go into a standby state; and, activating the switch (11) while the computer is in the standby state causes the computer to reset back to the normal operational state.

摘要： A computer network that includes a network server and a network client. The network server includes a storage medium configured with boot code data preferably comprising operating system software for the network client. The network client includes a power status indicator and is configured to query the power status indicator as part of a boot code sequence that is initiated in response to a boot event. The network client is configured to schedule retrieval of boot code data from the network server based upon the power status indicator. Preferably, the power status indicator includes a power fail circuit that indicates whether power to the network client has failed since a previous boot event. In one embodiment, the power fail circuit includes a flip flop arranged such that the output of the flip flop is preset when power is restored to the network client after a power failure. Preferably the clear input of the flip flop is programmably assertable. The power status indicator preferably further includes a power mode indicator that conveys information about the last known power mode of the network client. Preferably, the power mode indicator includes at least one nonvolatile memory bit.

摘要： A network computer including a motherboard powered by a power supply via a single power supply plane, a clock generator, a processor, a system memory, and a network interface. The network computer is configured to assume a low power state in response to a low power event and further configured to transition from the low power state to a full power state in response to a wake up event. The wake up event may comprise a LAN wake up in the form of a command issued by a server computer coupled to the network computer via a network. In one embodiment, the network computer lacks a disk based storage device, but includes local permanent storage comprising a compact flash card. Preferably, the network computer's clock generator is configured to produce a clock signal for the processor when the network computer is in the full power mode, and further configured to produce no clock signal in the low power mode. In one embodiment, the network computer further includes at least one peripheral device coupled to the processor via a peripheral bus, such as a PCI bus. In this embodiment, the computer is preferably configured to transition each peripheral device on the peripheral bus to a power management mode when the network computer enters low power mode. The wake up event may be a LAN wake up event in which a wake up signal is received via the network interface, or a “wake on ring” event in which the wake up signal is received via a modem connection to the computer.

摘要： A method and system for booting a multiple network adapter user station in a computer network are disclosed. The user station includes at least first and second network adapters. Initially, one of the adapters is selected based upon an ordering of the adapters. The user station then determines whether the selected adapter is connectable to the computer network. If the selected adapter is not connectable to the network, an iterative process is initiated in which a next adapter is selected and a determination made as to whether the next adapter is connectable to the network. Upon successfully determining which adapter is connectable to the network, the adapters are re-ordered to prioritize the adapter connectable to the network such that the network connectable adapter is selected first during a subsequent boot attempt. Determining whether the selected adapter is connectable to the computer network may include attempting to boot the user station from a remote server using the selected adapter. The ordering of the adapters may be recorded in and retrieved from a list in a nonvolatile storage device of the user station. The adapter list may be edited by a user to re-order the list of adapters. At least one of the network adapters may comprise an Ethernet adapter while at least one other adapter may comprise a token ring adapter.

摘要： A compact connector for a data processing system motherboard facilitates the performance of diagnostics on data processing system components. The connector includes first, second, and third terminals in communication with respective first, second, and third lines in the motherboard for serial port interrupts, system data, and keyboard interrupts, respectively. In an illustrative embodiment, the first and second lines comprise lines of an Industry Standard Architecture (ISA) bus, and the compact connector also includes a fourth terminal in communication with a fourth line in the motherboard for real-time-clock interrupts. This embodiment allows the motherboard to receive real-time-clock interrupts via the connector, so that a startup program of the data processing system may boot to an operating system that requires a real-time-clock. That operating system may then be utilized to test the motherboard. In addition, this embodiment allows one or more input devices in communication with the connector to be utilized to interact with the motherboard.

摘要： Initially, a SMI trap detects an application accessing a memory location associated with a physical hardware device. The SMI trap receives the device address for the address bus and compares that address with memory addresses for hardware devices being virtualized by virtual device simulators. If the address matches an available virtual device, the SMI caches the address, hooks and caches the corresponding IO instruction for the memory address and issues a SMI. A SMI handler receives the SMI and determines which virtual device simulator to call. Once activated by the SMI handler, the virtual device simulator interacts with the application and then returns control to the processor.
