An in-band/out-of-band alert delivery system for a computer system manager includes an alert log which maintains a record of alerts to be delivered and the status of those alerts, an alert manager for making a first attempt to deliver each alert, and a retry manager for making subsequent attempts to deliver alerts as becomes necessary and appropriate. The alert delivery system may also include a bus master interface manager for making in-band alert deliveries and a communications manager for making out-of-band alert deliveries. Telephone numbers are provided to the communications manager by an alert destination list. Out-of-band alert deliveries may be made via a modem, a universal asynchronous receiver transmitter, or the like.

A protocol for communicating messages between a manager for a computer system and a remote facility asynchronously connected with the system manager and a method for exchanging messages using the protocol. The protocol determines whether the system manager is ready to exchange messages with the remote facility, determines whether the remote facility is ready to exchange messages with the system manager and exchanges messages between the system manager and the remote facility. To exchange messages, a command message which includes a first field for identifying a command transmitted by the command message and a second field for identifying the command message is transmitted. In response, a command reply message which includes a first field for identifying the command to which the command reply message is in response to, a second field for matching the command response message to the command message and a third field for transmitting a response to the command message is transmitted.

A remote console emulation for a computer system manager operates by transferring video screen images from system memory to the remote console and by inserting keystrokes from the remote console into the system keyboard controller. This emulation constitutes a marked improvement over prior art emulations because it does not require software on the host system.

A remote system reboot facility effects reboots by resetting the central processing unit within a local or host console and by effecting a bus reset. The remote system reboot facility is actuated by signals transmitted over an asynchronous line from a remote console to a computer system manager within the host. The computer system manager, and possibly also a keyboard controller associated with the computer system manager, generates or generate the reset signals. Effectively, cold booting is accomplished by the remote simulating the effect of power cycling on the host and warm booting is accomplished by emulation of 'control'--'alt'--'del' keystrokes.

A system for innately monitoring a computer system. All address and data signals transferred over the system bus. Certain ones of the address signals are selected as related to the operating conditions of the computer system. A data filter selects data signals which correspond to the selected address signals and the selected address and data signals related to operating conditions of the computer system are then stored, either in a register if the selected address and data signals are composed of dynamic information requiring frequent status updates or in a first-in, first-out memory, when the selected address and data signals are composed of less dynamic information.

Innate bus monitoring system for computer system manager

A system manager for a computer system. The system manager transparently monitors signals transferred between computer system components along a system bus and stores objects related to the monitored signals in an object space. Information related to operating conditions within the system can then be provided from the object space. Later, the object space can be updated and the updated object space used to provide updated information regarding the operating conditions of the system.

Computer system manager for monitoring events and operating parameters

A protocol for local data transfers between a system manager for a computer system and a network operating system associated with the computer system and a method for exchanging command and response messages between the system manager and the network operating system using a bus master interface provided between the two. Various ones of the interface registers are reserved by the side transferring information, command written to the interface registers and the other side notified of the information transferred to the interface and the reservation released. The interface is also used to transfer responses to the side originating the command.

Computer implemented method for transferring command messages between a

A power supply for a computer system manager, wherein the power supply has its own secondary power source operable when input power to the system manager no longer meets preset threshold values. The power supply functions in one of a discrete number of power modes depending upon the amount of energy available from either the computer input power or the secondary power source. The power supply switches to one of the group of power modes to conserve secondary power when the computer input power is no longer available. The power modes are controlled by a power mode controller which selectively directs power to discrete components of the system manager as a power conservation technique. The power mode controller always energizes the random access memory of the system manager in order to maintain data integrity. Upon detecting insufficient energy within the secondary power source, the power mode controller terminates all power flow from the power supply, including power flow to the random access memory, at which point the entire system has lost all data and configuration settings.
