摘要： Memory is logically partitioned into two regions. A first region may be a similar size relative to the second region or the first region may be a small subset of the memory. The first region of memory is initialized and an operating system utilizes the first region. A system handler simulates a physical hot add of the second region. After the simulated physical hot add, the operating system may utilize the second region as if it were newly added physical memory and/or may utilize both the first region and second region.

摘要： This invention generally provides a method for speeding up system boot time, by initializing a subset of memory during the system firmware test/initialization, and allowing the system to boot an operating system with this subset of installed memory. While the system is completing the operating system boot with the subset of installed memory, a remainder of the installed system memory is being initialized/tested. When the initialization the remainder of system memory is completed (and after the OS has booted), the SMI handler is invoked. The SMI handler then simulates a physical memory “Hot Add” event, and reports the event to the OS. This allows much of the memory initialization/test activity to occur in parallel with the firmware initialization/test and operating system startup processes.

摘要： A method identifies a plurality of PCI devices in a computer system by an associated PCI device handle, wherein each of the PCI devices is also associated with a default EFI device driver. The method further identifies a target PCI device to be disabled from within the plurality of PCI devices, provides a dummy driver that enables fewer functions for the target PCI device than would the default EFI device driver, and binds the dummy driver to the target PCI device instead of binding the default EFI device driver associated with the target PCI device. The dummy driver may be used to effectively disable the target PCI device so that the POST does not hang up or completes faster without loading the default EFI device driver.

摘要： A method, computer program product and system for controlling the maximum turbo mode of a processor in a turbo boost state. The method comprises limiting a maximum turbo mode available to the processor by over-reporting the amount of current drawn by the processor to the current monitoring feedback line to the processor, wherein the processor uses the over-reported current to maintain operation of the processor within performance specifications of the processor. An automatic calibration routine may be used to determine nominal amounts of current over-reporting that may be used to prevent the processor performance from exceeding the maximum turbo mode. In one embodiment, a digital potentiometer is included in the voltage regulator circuit to over-report the current as instructed.

摘要： Detection of a reset failure in a multinode data processing system is provided by a diagnostic circuit in each of a plurality of the server nodes of the system. Each diagnostic circuit is coupled to a code fetch chain of its corresponding node. At reset, prior to a node processor retrieving startup code from the code fetch chain, the diagnostic circuit provides diagnostic signals to the code fetch chain. A problem in the code fetch chain is detected from a response to the diagnostic signals. When a problem is detected, a node failure status for the problem node may be signaled to the other nodes. The multinode system may be configured in response to signaled node failure status, such as by dropping failed nodes and replacing a failed primary node with a secondary node if necessary.

摘要： A method and system for emulating a hardware Internet Small Computer System Interface (iSCSI) Host Bus Adapter (HBA) without risking an interruption of communication between a computer and a remote secondary storage device is presented. During normal operations, a (hardware emulating) software iSCSI HBA drives a Network Interface Card (NIC) to afford communication between the computer and the remote secondary storage. If an operating system (OS) anomaly occurs in the computer, the NIC is normally disconnected by the OS. To maintain communication between the computer and the secondary storage device if such an event occurs, a failover network device is called up by the computer's System Management Memory (SMM) Basic Input Output System (BIOS), which allows uninterrupted communication to continue between the computer and remote secondary storage device.
