Abstract
Abstract 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
263 words
For a computer network having at least one computer system operatable therein, said computer system having a plurality of components interconnected by a system bus for the transferring of information between said components, said computer system further having a local console and a remote console, said local console being connected to the system bus and said remote console being connected to the computer system via an asynchronous line, said local console having a local central processing unit and a system board therein, a remote system reboot facility comprising: means for resetting said local central processing unit, said means for resetting disposed within said local console; means for effecting a bus reset, said bus reset being when said system bus is supplied with a driver reset signal which causes said system board to be reset, said means for effecting disposed within said local console; means for triggering said means for resetting said local central processing unit, said means for triggering said means for resetting disposed within and independently actuatable at said remote console; means for triggering said means for effecting a bus reset, said means for triggering said means for effecting a bus reset disposed within and independently actuatable at said remote console; said asynchronous line interconnecting said means for resetting and said means for triggering said means for resetting, and further, said asynchronous line also interconnecting said means for effecting and said means for triggering said means for effecting, wherein said means for resetting and said means for effecting are independently triggerable via their respective means for triggering located at the remote terminal.
Claim 2
Dependent Claim
