Intel Server Management (ISM) Installation and User's Guide Serial Data and the Command Line Interface Performing a graceful OS shutdown requires a proprietary OS agent be present. If this agent is not present or unable to respond after 7 seconds, an error message will be displayed for the user and the command will terminate (no reset or power off performed). Graceful shutdown commands will not perform hard resets or power off if OS shutdown does not complete. This model varies from previous implementations of graceful shutdown requests. Table 8-5. Boot Option Parameters Parameter # Set In 0 Progress (volatile) Service 1 partition selector (semivolatile) a Service 2 partition scan (semivolatile) a BMC boot 3 flag valid bit clearing (semivolatile) a Boot info 4 Parameter Data (nonvolatile unless otherwise noted) Data 1 - This parameter is used to indicate when any of the following parameters are being updated, and when the updates are completed. The bit is primarily provided to alert software that some other software or utility is in the process of making changes to the data. The change shall take effect when the write occurs. [7:2] - Reserved [1:0] - 00b = Set complete. If a system reset or transition to powered down state occurs while set in progress is active, the BMC goes to the set complete state. If rollback is implemented, going directly to set complete without first doing a commit write causes any pending write data to be discarded. 01b = Set in progress. This flag indicates that some utility or other software is presently doing writes to parameter data. It is a notification flag only, it is not a resource lock. The BMC does not provide any interlock mechanism that would prevent other software from writing parameter data while. 10b = Reserved 11b = Reserved Data 1 [7:0] - Service partition selector. This value is used to select the service partition from which BIOS should boot. This document does not specify which value corresponds to a particular service partition. 00h = Unspecified. Data 1 [7:2] - Reserved [1] - 1b = Request BIOS to scan for specified service partition. BIOS clears this bit after the requested scan has been performed. [0] - 1b = Service Partition discovered. The BIOS sets this bit to indicate it has discovered the specified service partition. The BIOS must clear this bit on all system resets and power-ups, except when a scan is requested. Data 1 - BMC boot flag valid bit clearing. Default = 0000b. [7:5] - Reserved [4] - 1b = Do not clear valid bit on reset/power cycle caused by PEF [3] - 1b = Do not automatically clear boot flag valid bit if IPMI Chassis Control command not received within 60-second timeout (countdown restarts when a IPMI Chassis Control command is received) [2] - 1b = Do not clear valid bit on reset/power cycle caused by watchdog timeout [1] - 1b = Do not clear valid bit on pushbutton reset / soft-reset (Ctrl-Alt-Del) [0] - 1b = Do not clear valid bit on power up via power pushbutton or wake event These flags are used to allow individual parties to track whether they have already seen and handled the boot information.
