Abstract: A fault tolerant method of powering up and powering down a server through either a local or remote client machine. The remote machine accesses the server by use of a dial-in modem connection, while the local machine accesses the server by a local serial connection. The power up operation brings the server to a maintenance state such that diagnostics or recovery can be performed even though the server operating system software is not operational. Power down is used when certain types of diagnostic, maintenance, or administrative tasks need to be done.

Abstract: Bracket for connection to a chassis of an electronic apparatus without the use of screws is described. The bracket may feature a support arm having at least one connection means, a ledge portion connected to the top of the support arm, and a flexible section connected to the ledge portion. The flexible section may extend at an angle to the ledge portion to impart a tension force on the chassis when installed, and contains an engagement device for attachment to a chassis connection element. In a described embodiment, when installed, a protrusion of the flexible section engages a pre-existing hole in the chassis of the electronic apparatus, and the flexible section exerts a bias force against the chassis to ensure a secure connection. The bracket may also include a handle attached to the flexible section, to permit a person to disengage the engagement device of the flexible section from the chassis connection element.

Abstract: An attachment assembly for removably mounting a computer component to a chassis. The assembly includes first and second engaging members. The first engaging member has a first protrusion which extends away from the first engaging member and is received by a first aperture positioned in a first surface of the component. The second engaging member has a second protrusion extending away therefrom and is received by a second aperture positioned in a second surface of the component to substantially prevent motion of the assembly relative to the component. The assembly further includes a chassis coupling member which engages first and second surfaces of the chassis to restrict motion of the assembly and the component to which it is attached relative to the chassis.

Abstract: The present invention provides a method for identifying components based upon selected physical characteristics. Initially, a characterization function that will produce a unique characterization value within a set of components, is (or has been) assigned to the set of components. The characterization function is a function of at least one physical characteristic that is shared by the components within the set of components. Next, the measurable physical characteristics defined as part of the characterization function are measured by testing. A characterization value, which is calculated from the assigned characterization function, is determined for each component. Each component that is to be subsequently identified is then identified by its associated characterization value.

Abstract: A computer system having a motherboard that is adapted to receive a daughterboard containing a CPU coupled to a PCI bus and a memory device through a system controller. The PCI bus is, in turn, coupled to a storage device, such as a programmable array logic device, containing CPU data identifying the type of CPU or other hardware installed on the daughterboard. The motherboard includes a memory device storing a BIOS program as well as a startup program. The startup program is executed by the CPU at power up or reset to cause the CPU to compare the CPU data identifying the CPU to BIOS data identifying the CPU adapted to execute the BIOS program. In the event that the CPU data and the BIOS data match, the CPU executes the BIOS program in a normal manner. In the event the CPU data does not match the BIOS data, the CPU executes a crisis recovery routine which may involve writing the proper BIOS program from a floppy disk to a programmable memory device containing the BIOS program on the motherboard.

Abstract: In a method and apparatus for displaying data on a video display that is controlled by a video controller, the video controller is coupled to a high-speed memory and a low-speed memory. The memories have separate data paths. A video address corresponding to a location on the video display is received. If a specified address bit is in a first state, then data is displayed from the high-speed memory. If the specified address bit is in a second state, then data is displayed from the low-speed memory. The specified address bit may be a high order address bit that is not utilized by a conventional VGA controller to transmit address information.

Abstract: One embodiment of the present invention provides a system for skipping a track on a disc in a disc player. Unlike current systems, this system does not rely on identifying tracks to be skipped based upon which slot a disc is located in. Instead, one embodiment of the present invention identifies discs based upon identification data read from discs in the disc player. Thus, one embodiment of the present invention provides an apparatus for playing discs that skips a track on a disc. The apparatus includes a disc player including a sequencing mechanism that generates a sequence of tracks from discs in the disc player. The disc player also includes an identification mechanism within the disc player that reads identification information from discs in the disc player and determines from the identification information if a specific disc is in the disc player.

The configuration system creates and maintains a memory structure having bus and device configuration information. The system includes a configuration manager which creates a memory structure containing configuration information for a bus and devices located on the bus within the computer system in which it operates. When a device on the bus is replaced, the configuration manager retrieves the configuration information for the replacement device from the memory structure and uses that information to configure the replacement device. In another aspect of the invention, when a device is added on the bus in the computer system, the configuration manager retrieves selected configuration information for the added device from the memory structure and uses that information to configure the added device.

Abstract: One embodiment of the present invention provides a method for calibrating a rotary encoder including a rotatable disk including at least two index points located along a circumferentially extending row. These index points contain information specifying an angular position of the index point. This allows the rotary encoder to be calibrated by turning it through a sufficient angular displacement to ensure that an index point passes over a sensor. This sufficient angular displacement is less than a complete revolution because there are multiple index points along the circumference of the disk. This design allows a rotary encoder to be calibrated without turning it through a complete revolution. This is advantageous where turning the rotary encoder through a complete rotation is not possible or is inconvenient, for example in applications such as a wind direction indicator, a rudder position indicator or a joystick.

Abstract: One embodiment of the present invention provides a method for determining a source of failure during a failed file access in a computer system. This method generates a sequence of file references from a first location in the computer system, and maintains a record of parameters specifying the sequence of file references. The results of the sequence of file references are examined to detect a failure during a file reference. If a failure is detected, the failed file reference is reconstructed using the record of parameters, and is then retried to determine the source of failure. In between retries, the method allows various system components to be manipulated to isolate the source of failure. In one embodiment, these manipulations include: replacing hardware components; replacing system firmware; replacing software components; and inserting debug code into a program on the computer system.
