Support for using this command forspecific system resources is system-specific.Initial ownership for a system resourcesemaphore after various system events (poweron, system reset, etc.) is configurable on asystem-specific basis.Definition for System Resource = 00h(SMBus).Note: BIOS is the owner of all CPUSMBus segments until POST completes.After POST completes, BMC is the defaultowner of all CPU SMBus segmentsunless BIOS has gained ownership viathis command.Instanc Definitione0 CPU #1 SPD SMBus segments1 CPU #2 SPD SMBus segments2 CPU #3 SPD SMBus segments3 CPU #4 SPD SMBus segmentsRevision 1.1Intel ® Confidential 113
