System and method for providing instant video in an information handling system

摘要

Before initializing a memory of an information handling system, a method includes loading an image of a video option ROM code for a graphics interface device to a cache associated with a processor of the information handling system, and executing the video option ROM code to initialize the graphics interface device. The method also includes executing a memory reference code to initialize the memory, and while executing the memory reference code, providing status information from the graphics interface device.

1. A method comprising:
prior to initializing a memory of an information handling system:
loading an image of a video option read-only memory (ROM) code to a cache, wherein the video option ROM is for a graphics interface device of the information handling system and the cache is associated with a processor of the information handling system, and wherein the image of the video option ROM code is loaded from a basic input/output (BIOS) ROM device associated with the information handling system;executing by the processor the video option ROM code to initialize the graphics interface, wherein executing the video option ROM code further comprises:
fetching instructions of the video option ROM code from the video option ROM device; andexecuting write instructions of the BIOS ROM code to the cache; andexecuting a memory reference code to initialize the memory.
