摘要： Arrangements for physically partitioning a bus having a well defined architecture as a physical entity, wherein the partitioning is logically transparent to a computer and devices which communicate through the bus and serves to avoid problems potentially arising because of the scope of actions permitted by the architecture. A typical bus architecture to which present arrangements have relevance is that associated with SCSI (Small Computer System Interface) buses. The potential problems allowed to occur architecturally involve: (a) exposures of data security/integrity; (b) excessive signal degradation due to use of signal rates which although allowed by the architecture are inappropriate for a particular bus loading environment also allowed by the architecture; (c) restrictions preventing parallel transfer of data between the computer and multiple storage devices; (d) restrictions unduly limiting the number of devices attachable to one logical bus path (one input-output channel of the computer). The disclosed arrangement partitions the bus into two or more physical entities which to the computer appears as one logical entity.

摘要： On board diagnostic capability for a SCSI controller is provided within an adapter by providing a gate array driven by a microprocessor on board the adapter. The gate array has data and control inputs driven from the microprocessor and data and control outputs which are dot OR'ed with corresponding in/out terminals of the SCSI controller. A reset signal from a SCSI bus forms a further input to the gate array. For testing purposes the microprocessor drives the gate array inputs to simulate a fault-free or faulty device. The microprocessor detects the response of the SCSI controller to the device simulation and thereby can determine the state of health of the SCSI controller.

摘要： Apparatus and method for increasing efficiency of command execution from a host processor over an SCSI bus. Arbitration, selection and message out functions of SCSI protocol are implemented using a background arbitration state machine. Additional protocol functions are implemented in a foreground state machine. When the host processor issues a command for access to the SCSI bus, the background state machine can be programmed before the foreground machine completes the protocol function for a previous command. Thus, the background state machine is ready to arbitrate for access to the bus at the very next bus free condition.

摘要： Apparatus for assigning addresses to devices connected to a small computer system interface (SCSI) bus. A second configure bus interconnects address assignable devices on the SCSI bus. The assignable devices may be used in a mixed system where some devices have fixed non-assignable addresses. The master device in the SCSI bus transmits configuration commands over the configuration bus and addresses for assignment over the SCSI bus. Acknowledgements are received back from a device which has accepted an address. Once configured with an address, the device propagates subsequent configuration commands to an adjacent device.

摘要： This invention relates to personal computers and, more particularly, to a personal computer having an interface controller providing an economical way to achieve access to a direct access storage device by a small computer system interface. In accordance with this invention, the system CPU is selectively allowed to access all or only a portion of the internal registers in an interface controller, enabling implementation in conjunction with a conventional subsystem microprocessor interface to the registers if desired. With this change, either interface has full access to the interface controller's internal registers. By allowing such access, the number of component parts required can be reduced where multitasking possibilities are not desired, and the cost of providing SCSI capability significantly reduced.

摘要： In order to more effectively use read only memory space of a personal computer system, ROM code is selectively located or mapped to either an address boundary which is an even or odd integer multiple of one half the capacity of the read only memory device in which the ROM code is stored. The ROM code is stored in the read only memory device in two fields. In a first field, the ROM code is broken up into two segments, and the first segment precedes the second segment. In the second field, the same two segments are stored, but the second segment is stored preceding the first segment. A register, for storing page select bits, provides an input to an address decoder and an input to an adder, which adds unity to the contents of the register and provides its outputs to the address decoder as well. Accordingly, the address decoder will respond to either the page which is identified by the page select bits or the page following the identified page. The LSB of the page select bits is used in addressing the read only memory device to select between the first field (selected when the LSB is zero) or the second field (selected when the LSB is unity).

摘要： This invention relates to personal computers, and more particularly to a personal computer using a small computer systems interface (SCSI) controller coupled directly to the local processor bus for controlling data transfer with storage memory devices such as fixed or removable media electromagnetic storage devices. The personal computer system has a high speed local processor data bus, at least one logical processor device coupled directly to the local processor bus and capable of signalling through the local processor bus an occurrence of the transfer of blocks of data, and a storage controller coupled directly to the local processor bus for regulating communications between the processor device and storage memory devices. The storage controller has a FIFO memory for transitory storage of blocks of data being exchanged with the local processor bus and is capable of signalling through the local processor bus the state of the FIFO memory. The processor device and storage controller cooperate for exchange of blocks of data between the local processor bus and FIFO memory when the FIFO memory has available one of data to be transferred and space for reception of data and for emptying of the FIFO memory through the local processor bus as necessary.

摘要： A method for supporting multiple interface standards in a connection between a computer system and a Redundant Array of Independent Disks (RAID) unit is disclosed. The method includes receiving a message indicating an initialization routine and reading a first indicator associated with a first interface standard. The method further includes loading configuration data for the first interface standard. The method further includes configuring a RAID initiator using the configuration data, if the first interface standard is identical to the actual interface standard to which the RAID unit is coupled.
