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.

Claims (44)

1. 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.

2. The information handling system of claim 1 , wherein the first video content comprises static image information and dynamic image information.

3. The information handling system of claim 2 , wherein the dynamic image information includes first information associated with a first step of the first in time portion of the boot process.

4. The information handling system of claim 3 , wherein the dynamic image information changes to include second information associated with a second step of the first in time portion of the boot process.

5. The information handling system of claim 3 , wherein the security co-processor provides first status information to the BMC related to the first particular step.

6. The information handling system of claim 1 , wherein, prior to providing the first video display content, the BMC initializes a video controller of the BMC.

7. The information handling system of claim 6 , wherein, prior to providing the second video display content, the data processor reinitializes the video controller.

8. The information handling system of claim 1 , wherein the data processor does not operate during the first in time portion of the boot process.

9. 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.

10. The method of claim 9 , wherein the first video content comprises static image information and dynamic image information.

11. The method of claim 10 , wherein the dynamic image information includes first information associated with a first step of the first in time portion of the boot process.

12. The method of claim 11 , further comprising:

changing, by the BMC, the dynamic image information changes to include second information associated with a second step of the first in time portion of the boot process.

13. The method of claim 11 , further comprising:

providing, by the security co-processor, first status information to the BMC related to the first particular step.

14. The method of claim 9 , further comprising:

initializing, by the BMC, a video controller of the BMC prior to providing the first video display content.

15. The method of claim 14 , further comprising:

reinitializing, by the data processor, the video controller, prior to providing the second video display content.

16. The method of claim 9 , wherein the data processor does not operate during the first in time portion of the boot process.

17. 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.

18. The BMC of claim 17 , wherein the first video content comprises static image information and dynamic image information.

19. The BMC of claim 18 , wherein the dynamic image information includes first information associated with a first step of the first in time portion of the boot process.

20. The BMC of claim 19 , wherein the dynamic image information changes to include second information associated with a second step of the first in time portion of the boot process.
