    Abstract: An apparatus and method for loading BIOS stored on a direct access storage device (62,66) into a personal computer system (10). The personal computer system (10) comprises a system processor (26), a system planar (24), a random access main memory, a read only memory (36), and at least one direct access storage device (62,66). The read only memory (36) includes a first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS initializes the system (10) and the direct access storage device (62,66) to read in a master boot record into the system (10) from the direct access storage device (62,66). The master boot record includes a data segment (122-138) and an executable code segment (120). The data segment (122-138) includes data representing system hardware and a system (10) configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment (122-138) of the master boot record agrees with the system processor (26), system planar (24), and planar I/O configuration. If the master boot record is compatible with the system hardware, the first BIOS portion vectors the system processor (26) to execute the executable code segment (120) of the master boot record. The executable code segment (120) confirms that the system configuration has not changed and loads in the remaining BIOS portion from the direct access storage device (62,66) into random access memory (32). The executable code segment (120) then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the BIOS now in random access memory (32). BIOS executing in random access memory (32) then boots up the operating system to begin operation of the personal computer system (10).

    Abstract: For facilitating data communication between entities in a local area network (storage files, programs, devices, human operators, etc.), a method is disclosed for addressing such communications to logical names adopted for the entities; rather than to discrete physical locations in the network. The subject method allows for extension of name-directed communications across bridges (between separate communication media or between discrete frequency channels on one medium). Extensions of such communications across bridges are conditioned on the handling of respective communications within the channel or medium leading to respective bridges. If a named entity is reachable within a channel or medium leading to a bridge, the communication will be acknowledged by the processing facility at the node serving that entity, and the communication will not be extended. With the present method, a program running on a processor at one node of the network may call for retrieval of a data set by name, where the location of the data set need not be known or specifiable by either the program or the processor, and the respective data set may be retrieved through a process of communication which is entirely transparent to the program and processor, and also not ambiguous or burdensome when ■ the network path to the named data set contains bridges and/or gateways.

    Abstract: An apparatus and method for decreasing the memory requirements of BIOS in a personal computer system (10) includes storing a first portion of BIOS in memory and a second portion on a direct storage access device. The personal computer system (10) comprises a system processor (26), a random access main memory, a read only memory (36), and at least one direct access storage device (62,66). The read only memory (36) includes the first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS only includes routines for initializing the system (10) and the direct access storage device (62,66) to read in a master boot record into the system (10) from the direct access storage device (62,66). The master boot record includes a data segment (122-138) and an executable code segment (120). The data segment (122-138) includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment (122-138) of the master boot record agrees with the system processor (26), system planar (24), and planar (24) I/O configuration. If the master boot record is compatible with the system hardware, the first BIOS portion vectors the system processor (26) to execute the executable code segment (120) of the master boot record. The executable code segment (120) confirms that the system conf iguration has not changed and loads in the remaining BIOS portion from the direct access storage device (62,66) into random access memory (32) superseding the first BIOS portion. The executable code segment (120) then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the remaining BIOS now in random access memory (32). The remaining BIOS in main memory includes reusable routines for operating the system (10) in a normal manner.
