A computing system using a persistent, unique identifier may be used to authenticate the system that ensures software and configurations of systems are properly licensed while permitting hardware components to be replaced. The persistent, unique system identifier may be coupled to serial numbers or similar hardware identifiers of components within the computing system while permitting some of the hardware components to be deleted and changed. When components that are coupled to the persistent, unique identifier are removed or disabled, a predefined time period is provided to update the coupling of the persistent, unique identifier to alternate hardware component in the system.

System and method for providing a mechanism to virtualize a perpetual, unique system identity on a partitioned computer system

A method and system for maintaining the execution speed of a multiprocessor computer system includes automatically detecting a change in instruction execution rate in a disabled processor by a threshold amount and determining an amount of change in instruction execution rate to adjust an actual system-level instruction execution rate to approximate a target system-level instruction execution rate. The target system-level execution rate being pre-determined. Thereafter, the method adjusts one or more instruction processor execution rates such that the actual system-level instruction execution rate approximates the target system-level instruction execution rate to overcome the loss of the disabled processor. One embodiment of the invention involves the use of a processor key for licensing of processor resources within the computer system and offers the option of enabling a dynamic processor recovery method as well as an automatic execution rate regulation method.

System and method for maintaining a constant processor service level in a computer

A method and apparatus enables a newly installed peripheral device such as a disk device to be used with a computer system without changing the operating system. The peripheral device is identified as a type which is not recognized by an operating system operating in conjunction with the computer system. A value which identifies at least one logical attribute of said peripheral device is obtained from said peripheral device. A determination is made as to whether the operating system and the peripheral device are compatible based on the logical attribute obtained from the peripheral device. The operating system and the peripheral device communicate if it is determined that the operating system and the peripheral device are compatible (i.e., can operate together).

Self-identifying peripheral device

System and method of encouraging computer system customers to purchase licenses before employing certain types of peripheral devices for use with their computer system. The computer system establishes contact with a peripheral device. It then verifies that the peripheral device is supported by the operating system. If the peripheral device is supported, the system determines whether the peripheral device is licensed (and therefore requires a driver license key in order for the peripheral device to be accessed by the system). If the peripheral device requires a driver license, the system determines whether the corresponding driver license key is installed in the keys file of the computer system. If the driver license key is not installed, the system compels (or encourages) installation of the driver license key by (1) displaying a licensing violation message instructing the customer to obtain the proper license; and/or (2) precluding access of the peripheral device by the computer system.
