Multiple PCI adapter cards are supported by a single PCI slot through the aspects of the present invention. A computer system aspect includes an &mgr;ATX planar including at least one PCI slot, and a riser card mounted in the at least one PCI slot, the riser card supporting multiple PCI adapter cards and providing signal generation to allow the multiple PCI adapter cards to utilize the at least one PCI slot. The riser card aspect includes a PCI connector for coupling to a PCI slot on the &mgr;ATX planar, a plurality of PCI slots for attaching a plurality of PCI adapter cards, and a logic device for providing separate bus signal pairs to each of the plurality of PCI adapter cards from a single signal pair of the PCI slot on the &mgr;ATX planar.

A system and method for installing a customized set of software on a personal computer, tailored to the requirements of the prospective user and avoiding unnecessary software and attendant license fees. Software (all that may be desired) in unusable form is loaded onto the personal computer then selected software (that which a particular user may require and/or desire) is converted (decompressed and/or decrypted) to produce usable versions of the selected software while the other software may be erased, if desired, to free up space in storage. The selection of software is done on the user's function (department and/or mission) and may be supplemented by a user selection from a menu, based on a selection utility.

Described is a computer system which is coupled to a remote computer via a network cable. The computer system has a normally closed enclosure and is capable of securing data retained within the system against unauthorized access and notifying the remote computer when an unauthorized access has occurred. The computer system includes an erasable memory element mounted within the enclosure for selective activation to active and inactive states and for receiving and storing a security password when in the active state. A manually operable option switch is mounted within the enclosure. The option switch is manually settable by a user of the computer system for setting the memory element to the active and inactive states. A tamper detection switch is mounted within the enclosure and operatively connected with the memory element for detecting opening of the enclosure and for generating a tamper alert signal and clearing any stored security password from the memory element in response to any switching of the tamper switch. The computer system further includes a network connector which is operative to receive the tamper alert signal and upon so receiving, transmit an alert packet over the communication line to the remote computer. The alert packet contains an alert message and information which specifically identifies the computer system.

A data processing system and method are disclosed for remotely recovering a client computer system's primary password. The primary password be correctly entered prior to the client computer system becoming fully accessible to a user. The client computer system is coupled to a server computer system utilizing a network. Prior to the client computer system completing a boot process, a user is prompted to enter the primary password. An interrogative password method is provided in response to an incorrect entry of the primary password. The primary password is recoverable in response to a successful execution of the interrogative password method. The primary password is recoverable from the server computer system by the client computer system prior to said client computer system completing said boot process utilizing the interrogative password method.

According to one embodiment, an apparatus for providing node redundant power to a system includes a plurality of devices, with each device including a power supply. Each power supply includes a first direct current (DC) input coupled to a first input of an OR logic gate, and a second DC input representing by an alternating current (AC) input. The second DC input is coupled to a second input of the OR logic gate, and at least one DC output is coupled to an output of the OR logic gate. Each power supply also includes a backup power supply for supplying a voltage coupled to a common node. The OR logic gate provides DC voltage to the DC output to power the system from the first DC input only when voltage from the AC input is not available.

Systems and methods to manage memory are provided. A particular method may include storing data in a primary memory that is in communication with a processor and storing in a mirrored data in a mirrored memory. The mirrored data may be compressed, and the mirrored memory may be in communication with the processor. A failure condition associated with the data of the primary memory may be detected. In response to the detected failure condition, the mirrored data in the mirrored memory may be accessed.

Systems and methods that provide power redundancy to a computer system without increasing the number of independent power supplies used. A system having N computing modules may have power redundancy using N power supplies, where each of the N power supplies are able to supply more power than required by an associated computing module, and where all but one (N−1) of the power supplies collectively can immediately supply power to any one of the computing modules when the power supply associated with that computing module fails.
