Abstract
An information handling system includes a data processor, a security co-processor, and a baseboard management controller (BMC). The security co-processor operates during a first in time portion of a boot process of the information handling system. The BMC provides first video display content during the first in time portion of the boot process. The data processor provides second video display content during a second in time portion of the boot process.
Claims20
An information handling system, comprising:
- a data processor;
- a security co-processor;
- and
- a baseboard management controller (BMC);
- wherein:
- the security co-processor operates during a first in time portion of a boot process of the information handling system, the first in time portion of the boot process being prior to the launch of a Basic Input/Output System (BIOS) of the information handling system;
- the BMC provides first video display content during the first in time portion of the boot process;
- and
- the data processor provides second video display content during a second in time portion of the boot process, the second in time portion of the boot process being during execution of the BIOS.

A method, comprising:
- operating a security co-processor of an information handling system during a first in time portion of a boot process of the information handling system, the first in time portion of the boot process being prior to the launch of a Basic Input/Output System (BIOS) of the information handling system;
- providing, by a baseboard management controller (BMC) of the information handling system, first video display content during the first in time portion of the boot process;
- operating a data processor of the information handling system during a second in time portion of the boot process, the second in time portion of the boot process being during execution of the BIOS;
- and
- providing, by the data processor, second video display content during a second in time portion of the boot process.
2 more elements
A baseboard management controller (BMC), comprising:
- a processor;
- and
- a video controller;
- wherein the processor:
- receives a system reset for an information handling system that includes the BMC;
- determines that a co-processor of the information handling system is executing a first in time portion of a system boot process, the first in time portion of the boot process being prior to the launch of a Basic Input/Output System (BIOS) of the information handling system;
- initializes the video controller in response to determining that the co-processor is executing the first in time portion of a system boot process;
- provides first video display content to the video controller during the first in time portion of the boot process;
- determines that a data processor of the information handling system is executing a second in time portion of the system boot process;
- and
- releases the video controller to be controlled by the data processor during a second in time portion of the boot process, the second in time portion of the boot process being during execution of the BIOS.
