摘要:
A maximum power usage setting for a computing device is based on one or more of: a user-specified setting corresponding to how often a frequency of a processor of the computing device is likely to have to be decreased to reduce power usage by the computing device; an average frequency of the processor during a previous period in which the computing device was operated; a minimum frequency of the processor during the previous period; a maximum power that the computing device used during the previous period; and, a nominal frequency of the processor. When the computing device starts to use more power than the maximum power usage setting, the power used by the computing device is reduced so as not to exceed the setting, such as by decreasing the frequency at which the processor operates.

Apparatus and procedure for accurately positioning and magnetically holding a flexible ferrous plate on the surface of a rotary printing cylinder. Movable registering pins and a permanent bar magnet are mounted to the rotary cylinder and controlled by a single operating means. The pins and magnetic bar are alternately moved toward and away from the cylinder surface such that, when the pins are initially projected to register with positioning holes in the plate, the magnet is withdrawn. When the pins are withdrawn the magnet is simultaneously advanced to "grab" the leading edge of the plate. The operating means is controlled by a foot pedal linkage. The trailing edge of the plate is held in position by a second bar magnet. To remove the plate, the procedure is reversed so as to simultaneously advance the register pins and retract the bar magnet to release the leading edge of the plate.

Mechanisms are provided, in a bare metal computing device, for executing a network based boot operation for booting the bare metal computing device. In response to powering-on the bare metal computing device, firmware is executed that executes a stub from a virtual media image accessible by the bare metal computing device. The configuration information of the bare metal computing device indicates that the bare metal computing device is being booted from a local media. The stub configures the firmware environment and a network boot program to utilize a network connection by modifying the configuration information of the bare metal computing device to indicate that the bare metal computing device is being booted from a network device. A control program is obtained from a remotely located boot server using the network boot program and is executed to complete the booting of the bare metal computing device.

A personal computer system is disclosed which is compatible with application programs and operating system software. The personal computer system includes a microprocessor electrically coupled to a data bus, non-volatile memory electrically coupled to the data bus, volatile memory electrically responsive to the data bus, a memory controller electrically coupled to the microprocessor, the volatile memory and the non-volatile memory, and a direct access storage device electrically responsive to the data bus. The non-volatile memory stores a first portion of operating system microcode and the volatile memory includes a volatile operating system portion intended for use by the first portion of the operating system microcode. The memory controller regulates communications between the volatile memory, the non-volatile memory and the high speed microprocessor. The direct access storage device stores a second portion of operating system microcode which is accessed by the microprocessor as needed.

A multi-color printing press having a single segmented impression cylinder with multiple, segmented blanket cylinders of equal diameter arranged about the periphery thereof. The segments of the impression cylinder and the blanket cylinders are equal in length and the number of segments on the impression cylinder is equal to the number of segments on the blanket cylinders multiplied by a whole number, plus one additional segment. Each blanket cylinder is provided with a plate cylinder of equal diameter which has the same number of segments. Color rolls provide each segment of the plate cylinder with a different color. Sheets to be printed are fed to the gripping means on the successive segments of the impression cylinder and delivery means removes sheets after printing. Each sheet is held on the impression cylinder for a number of revolutions equal to the number of segments on any one blanket cylinder.

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.

A plate clamping system and apparatus for holding a flexible printing plate in position on a rotary printing cylinder. The system includes a plate clamp assembly mounted in a gap in the wall of the rotary printing cylinder for holding the leading edge of the flexible printing plate and a tail clamp assembly mounted in the same longitudinal gap in the cylinder wall for gripping and applying tension to the flexible printing plate to hold it against the surface of the printing cylinder. The plate clamp includes a plurality of individual clamping mechanisms which are air pressure engaged and spring released to hold the leading edge of the flexible plate. The tail clamp assembly includes a plurality of tail clamp mechanisms which are spring applied and air pressure released. The tail clamp mechanisms have a two-stage operation wherein compression springs clamp the tail end of the printing plate and a second set of tension springs moves the mechanism to apply tension on the printing plate. The air cylinders of the clamp assemblies are connected by separate single air pressure lines to a union on the rotary shaft of the printing cylinder with air pressure to the clamping assemblies being individually controlled by means of foot pedal operated air pressure control units.

A multiprocessor computer includes a planar board and a processor card mounted on the planar board. An interrupt controller is mounted on the planar board and has a plurality of interrupt input lines for receiving interrupt requests from a plurality of interrupting devices. The interrupt controller also has an output line that transmits an interrupt to the processor card. The processor card includes an interrupt director having a plurality of interrupt request lines respectively connected to interrupt request pins of the different processors. The director is also connected to the output line coming from the interrupt controller. In response to receiving an interrupt request from the interrupt controller, the director performs an interrupt acknowledge cycle and transmits an interrupt request, on only one of the interrupt request lines, to a specific processor predetermined by the director. The specific processor then reads an interrupt vector from the director. The interrupt vector uniquely identifies the interrupt level and is used by the processor to execute an interrupt handler for that specific interrupt level.
