Problems solved by technology

At present, there are two common methods: one is that the management personnel go to the computer room to operate the server, and enter the BIOS Setup interface to modify the order of the BIOS startup items. However, this method is extremely inconvenient to operate and requires the management personnel to operate in the computer room; The other is to remotely control the server to enter the BIOS Setup interface through BMC’s built-in remote monitoring such as KVM, and modify the order of startup items. However, this method needs to log in to the server’s BMC client, which is inconvenient to implement.

Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The BIOS startup item is a set of sequential bootable device options composed of multiple devices that can be booted into the OS. The BIOS creates and maintains the sequence table of the bootable devices during the POST process, which is called Boot Option in the BIOS. Boot Option is an array of pointers, and each array item points to a bootable device. When the BIOS searches for a bootable device, it searches in the Boot Option array in sequence.

[0018] The intelligent platform management interface IPMI (Intelligent Platform Management Interface) provides two useful commands that can be u...

Abstract

The invention discloses a method for modifying the sequence of boot options of a basic input / output system (BIOS). The method comprises the following steps of: acquiring data which shows whether the boot options of the BIOS are needed to be modified or not and what sequence of the boot options is needed to be modified from a block multiplexer channel (BMC) through a Get System Boot Options Command of an intelligent platform management interface (IPMI); writing codes to modify the priority sequence of the boot options of the BIOS; and transmitting a Set System Boot Options Command to a target system through an IPMI tool and filling out corresponding parameters. By the method, the sequence of the boot options can be modified by adding a small number of logical codes into BIOS codes, a Boot option can be directly changed at a remote control end, and a server is not required to be restarted immediately; and after the Boot option of the server is directly changed by the IPMI tool, the normal operation of the server system is not influenced, and the Boot option becomes effective when the server is started next time.

Description

technical field [0001] The invention belongs to the technical field of computer BIOS, and relates to a method for modifying the sequence of BIOS startup items. Background technique [0002] In a basic server system, there are many different bootable devices, such as commonly used CD / DVD drives, floppy drives, hard drives, and bootable USB devices. All bootable devices will have a default boot order in the BIOS, for example: the first boot item is the CD / DVD drive, the second boot item is the floppy drive, and the third boot item is the hard disk. By default, the BIOS will try to boot into the OS one by one according to the order of the boot items. If the first boot item fails to boot, it will automatically try the next one until all bootable devices have been tried. [0003] In the process of using the server, sometimes the default boot sequence of the BIOS is changed for certain needs. At present, there are two common methods: one is that the management personnel go to th...
