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.
