Abstract: Diskette media and drive determination mechanism in which a diskette controller attempts to read the diskette according to a variety of formats having, for instance, different data transfer rates. A successful read is registered by the controller and that format is thereafter identified with the diskette drive and the diskette media inserted in the drive.

Abstract: This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. This invention contemplates protecting a personal computer system which has the capability of becoming a secure system from being placed into that condition by an attack on an unsecured machine. Additionally, in a network environment, it is important to maintain network security that any given particular system be uniquely identified to the network, in order to guard against the substitution of an insecure "alternate" which would open the network to attack through an insecure system. This invention contemplates provision for such identification in a secure manner.

Abstract: An apparatus and method for loading BIOS from a diskette drive into a personal computer system normally connected to a hardfile, such as a fixed disk. The personal computer system further includes a system processor, a random access main memory, a read only memory and a switching means. The switching means generates a signal to indicate a mode for whether BIOS loads from either diskette or disk. In a priority mode, BIOS loads immediately from diskette. In a recovery mode, BIOS loads from diskette after testing the disk subsystem. The read only memory includes a first portion of BIOS and data representing the type of system processor and system planar I/O configuration. The first portion of BIOS initializes the system and queries the switching means. If the fixed disk is not available or the master boot record on the disk is invalid, the first portion of BIOS reads in a master boot record from the diskette drive. For either mode, the master boot record includes a data segment and an executable code segment. The data segment includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion transfers control to the executable code segment which confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment of the master boot record agrees with the system processor, system planar, and planar I/O configuration. If the master boot record is compatible with the system hardware, the executable code segment confirms that the system configuration has not changed and loads in the remaining BIOS portion from the diskette drive into random access memory. The executable code segment then verifies the authenticity of the remaining BIOS portion and vectors the system processor to begin executing the BIOS now in random access memory. BIOS, executing in random access memory, then boots up the operating system to begin operation of the personal computer system.

Abstract: This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. In particular, a personal computer system in accordance with this invention has a normally closed enclosure, an erasable memory element for selective activation to active and inactive states and for receiving and storing a privileged access password when in the active state, an option switch operatively connected with the erasable memory element for setting the erasable memory element to the active and inactive states, a tamper detection switch operatively connected with the erasable memory element for detecting opening of the enclosure and for clearing any stored privileged access password from the erasable memory element in response to any switching of the tamper switch, and a system processor operatively connected with the erasable memory element for controlling access to at least certain levels of data stored within the system by distinguishing between the active and inactive states of the memory element and between entry and non-entry of any stored privileged access password. In the presently preferred form of the invention, two non-volatile erasable memory elements are provided, one an EEPROM and the other battery backed CMOS RAM.

Abstract: An apparatus and method for reclaiming a portion of random access memory in a personal computer system. The personal computer system comprises a system processor, a memory controller, a random access main memory, a read only memory, and at least one direct access storage device. The read only memory includes operating system microcode. The memory controller regulates communications between main memory and the system processor. In response to signals from the system processor, the memory controller can either execute the microcode out of the read only memory and recover main memory previously used to store the microcode, or disable read only memory, copy the microcode to main memory and execute the microcode out of main memory.

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).
