Systems and methods for command-based entry into basic input/output system setup from operating system

摘要

In accordance embodiments of the present disclosure, a method may include, during execution of an operating system on an information handling system and responsive to a user input indicating a desire to invoke a basic input/output system (BIOS) setup program for configuring a BIOS, prompting for and receiving user-provided credentials via a user interface communicatively coupled to the processor. The method may also include, during execution of the operating system, passing BIOS credentials to the BIOS based on the user-provided credentials. The method may additionally include, during execution of the operating system determining, by the BIOS, if the BIOS credentials are valid. The method may further include, responsive to determining that the BIOS credentials are valid, setting a flag to a value indicating that the BIOS setup program is to be invoked on a subsequent boot of the information handling system.

1. An information handling system comprising:
a processor; an operating system comprising one or more instructions embodied in computer-readable media communicatively coupled to the processor, the instructions for causing the processor to, when read and executed by the processor:
responsive to a user input indicating a desire to invoke a basic input/output system (BIOS) setup program for configuring a BIOS, prompt for and receive user-provided credentials via a user interface communicatively coupled to the processor; andpass BIOS credentials to the BIOS based on the user-provided credentials; and the BIOS comprising one or more instructions embodied in computer-readable media communicatively coupled to the processor, the instructions for causing the processor to, when read and executed by the processor:
determine if the BIOS credentials are valid;responsive to determining that the BIOS credentials are valid, set a flag to a value indicating that the BIOS setup program is to be invoked on a subsequent boot of the information handling system;during a boot of the information handling system, determine the value of the flag;during the boot and responsive to determining that value of the flag is set, invoke the BIOS setup program prior to loading and executing an operating system on the processor; andduring the boot and responsive to determining that value of the flag is not set, load and execute the operating system without invoking the BIOS setup program.
