Abstract
A method and system respond to a system reset by executing a BIOS that establishes pre-OS communication with a baseboard management controller (BMC) and determines the state of a flag maintained by the BMC. The flag indicates whether the system reset was part of a crash event or a controlled shutdown. If the flag indicated a crash event, contents of the server cache are copied to a persistent secondary memory. The content of the secondary memory may then be sent to a management resource and/or to a remote management system. Before booting to an operating system and resuming normal operation, the flag may be SET. When a subsequent system resent occurs, the flag is cleared if the system reset is part of a controlled shutdown. Otherwise, the flag will remain set to indicate the crash event when the boot sequence is initiated.
