Problems solved by technology

Therefore, similar UEFI extended applications are currently stored in the embedded memory (Embedded Multi Media Card, eMMC) chip controlled by the Baseboard Management Controller (BMC), and the BMC is virtualized into a USB device and mounted to the host The terminal is called by the host, but it depends on the USB bus from the BMC to the host (Host). The code stored in the eMMC chip can only be run after the Host BIOS completes the USB initialization and device operation, resulting in a late system startup time. Slow to start

Abstract

The embodiments of the invention provide an extension component, an electronic apparatus and a start method and aim at improving system start efficiency of an electronic apparatus. The extension component comprises a platform controller hub (PCH) which is connected with a central processing unit (CPU); a baseboard management controller (BMC) which comprises a first serial peripheral interface (SPI), wherein a first storage component is mounted under the BMC and stores main boot files of a basic input / output system; a second storage part which comprises a second SPI and is used for storing initialization boot files of the BIOS; an SPI bus used for mutual connection of the PCH, the BMC and the second storage part. When the BIOS is started, the second SPI is accessed via the SPI bus; the initialization boot files are executed and the first SPI of the BMC is accessed via the SPI bus, and the main boot files in the first storage part are read.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an expansion component, electronic equipment and a starting method. Background technique [0002] The Unified Extensible Firmware Interface (UEFI) is a standard describing in detail a new type of interface, which is applicable to a standard firmware interface of an electronic device. UEFI is a concept opposite to the Basic Input / Output System (BIOS). This interface is used to automatically load the operating system from the pre-boot operating environment to an operating system, so as to achieve the simplification of the boot program. Jane time-saving purpose. The traditional BIOS technology is gradually being replaced by UEFI. In the recent new computers, many of them have already used UEFI. Therefore, it is the trend to use UEFI mode to install the operating system. [0003] Currently, the size of the BIOS flash chip used by Intel x86-based server systems is usually 16MB t...
