Abstract

A critical area in desktop corporate computers is remote system management and reducing the total cost of ownership. One of the key methods is remotely waking up the system for system level maintenance. System level maintenance can include backing up critical files, virus scanning, or even downloading a new operating system. Currently, the system administrator, who initiates the waking up of the remote system, has no way of knowing if the system successfully booted and is ready for system level maintenance.

Power On Self Test Complete Alert for Remote Management System Level
Maintenance

      A critical area in desktop corporate computers is remote system
management and reducing the total cost of ownership.  One of the key
methods is remotely waking up the system for system level
maintenance.  System level maintenance can include backing up
critical files, virus scanning, or even downloading a new operating
system.  Currently, the system administrator, who initiates the
waking up of the remote system, has no way of knowing if the system
successfully booted and is ready for system level maintenance.

      The Local Area Network (LAN) administrator sends a Wake On LAN
(WOL) packet to the desktop computer.  The desktop computer receives
the WOL packet and starts the system level reboot to return the
desktop computer to a working state from power off.  When the desktop
computer is in the working state, the LAN administrator can start
remote system level  maintenance.  However, there is no way of
knowing if the desktop computer  successfully rebooted.  This
invention adds a Power on Self Test (POST)  complete alert to the
system level start-up code.  POST is the desktop  computer start-up
code.  When successfully completed, it indicates the  desktop
computer is operational.  This invention will detect a system hang
during POST and/or a successful boot.  During POST, checkpoints are
written to the service processor.  A timer is also set.  If the timer
