COORDINATED BOOT SYNCHRONIZATION AND STARTUP OF INFORMATION HANDLING SYSTEM SUBSYSTEMS: abstract simplified (17714824)

• This abstract for appeared for patent application number 17714824 Titled 'COORDINATED BOOT SYNCHRONIZATION AND STARTUP OF INFORMATION HANDLING SYSTEM SUBSYSTEMS'

Simplified Explanation

This abstract describes an information handling system that includes a processor, a subsystem, and a management controller. The management controller is responsible for managing the system, even when it is not actively running.

When the system goes through an alternating current power cycle, the management controller instructs the basic input/output system (BIOS) to pause its boot process before it starts recognizing the functions of the subsystem. Once the subsystem has completed its boot process and its virtual functions have been initialized, the management controller then allows the BIOS to continue its boot process and recognize all the functions of the subsystem, including the virtual functions.

Original Abstract Submitted

An information handling system may include a processor, a subsystem communicatively coupled to the processor, and a management controller communicatively coupled to the processor and the subsystem and configured for out-of-band management of the information handling system, the management controller further configured to, in response to an alternating current power cycle of the information handling system: cause a basic input/output system of the information handling system to pause its boot process prior to enumeration of functions of the subsystem; and upon completion of the boot process of the subsystem and initialization of virtual functions of the subsystem, cause the basic input/output system to unpause the boot process in order to enumerate the functions of the subsystem including the virtual functions.
