Description

A method, device and equipment for identifying UEFI OS startup items

technical field

The present invention relates to the field of computer design and calculation, in particular to a method, device, equipment and computer-readable storage medium for identifying UEFI OS startup items.

Background technique

BIOS (Basic Input Output System) is a set of programs that are solidified on a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, system setting information, self-test programs after power-on and system self-starting programs. . The BIOS is responsible for initializing the hardware, detecting the hardware and finally booting the operating system.

UEFI (Unified Extensible Firmware Interface) is a unified extensible firmware interface. It is a standard that describes a new type of interface in detail. It was jointly established by more than 140 technology companies in the UEFI alliance. UEFI is a standard computing interface for computers, designed to replace BIOS, improve software interoperability, and address the limitations of BIOS. At present, BIOS has been basically replaced by UEFI. The latest computers are all using UEFI, and the use of UEFIOS is also the trend.

To install UEFI OS, master boot record is no longer needed, active partition is no longer needed, and no tools are needed, as long as there is an EFI boot program in the hard disk partition. To recognize that UEFI OS has been installed, the existing technology is to pass in the BIOS. Add the path of the OS startup file, such as \\EFI\\Redhat\\grub.efi, and the BIOS will create the corresponding OS startup options based on the path. This method is feasible when an OS only corresponds to one path file, but some customer OS will create two paths at the same time, such as Centos, which will create \\EFI\\Centos\\shim.efi and \\ at the same time EFI\\Redhat\\grub.efi, in this case, the BIOS will create two startup items for Centos Redhat according to the path, but only one is bootable, which will cause boot failure.

In the prior art, the UEFI OS path is added to the BIOS system, and the customer data center cannot boot after updating and upgrading the BIOS in batches, and needs to manually add and adjust startup items or redeploy the OS.

From the above, it can be seen that how to boot the UEFI OS normally when the OS is updated and the OS hard disk is replaced is a problem to be solved at present.

Traversing the boot items in the BDS BOOT Device Select stage, identifying the boot items created by the client OS; judging that the boot path corresponding to the boot items created by the client OS is not in the UEFI OS path list, then saving the client The boot path corresponding to the boot item created by the OS is added to the UEFI OS path list.

Step S102: After saving the startup path to the UEFI OS path list, search for the target startup file according to the UEFI OS path list;

Step S103: Identify the UEFI OS startup item created according to the target startup file, and enter the BIOS system.

Searching for the target startup file according to the UEFI OS path list after saving the startup path, so as to identify the UEFI OS startup item created by the target startup file, thereby entering the BIOS system.

In this embodiment, a method for identifying UEFI OS startup items is provided. There is no UEFI OS path at the beginning of the BIOS. When the user installs the UEFI OS, the UEFI OS will create a startup item BOOTXXXX, and the BIOS will create and save it according to this startup item. This OS path, since these paths are created by the client OS, must be bootable, which can solve the problem that the client OS creates multiple OS paths. When the customer updates the BIOS, the BIOS will reserve these paths by default, which not only meets the requirements of the OS installed before the BIOS update, but also avoids the disadvantages of writing as many OS paths as possible in advance in the BIOS.

On the basis of the above embodiments, in this embodiment, search for the target startup file according to the UEFI OS path list: determine whether the current startup item has a startup item with the same path as the target startup file; if it exists, then After traversing the current startup items and deleting duplicate startup items, enter the BIOS system according to the startup sequence in the target startup file. Please refer to Fig. 2, Fig. 2 is the flow chart of the second specific embodiment of the method for identifying UEFI OS startup items provided by the present invention; The specific operation steps are as follows:

Step S201: traversing the startup items in the BDS stage, saving the startup path corresponding to the startup item created when the user installs the UEFI OS, and saving it in the UEFI OS path list;

Step S202: After saving the UEFI OS path list for saving the boot path, search for the target boot file according to the UEFI OS path list;

Step S203: judging whether the current startup item has a startup item with the same path as the target startup file;

Step S204: If it exists, traverse the current startup items and delete duplicate startup items;

Step S205: If there is no startup item with the same path as the target startup file among the current startup items, then create a UEFI OS startup item according to the target startup file;

Step S206: Identify the UEFI OS startup item created according to the target startup file, and enter the BIOS system;

Step S207: When the BIOS system needs to be updated, use the UEFI OS path list that stores the boot path corresponding to the boot item created when the user installs the UEFI OS to search for the target boot file, thereby creating a UEFI OS boot item, and start the update BIOS system.

It should be noted that the method provided in this embodiment is also applicable to retaining the UEFI OS startup path of the client when updating the BIOS in other ways, such as updating through the BMC, replacing a defective motherboard, and the like.

In the method provided in this embodiment, the startup items created by the UEFI OS are used to identify the real startup path of the client OS, and the BIOS retains and uses these startup paths to ensure that it can be used normally in different application scenarios such as updating the OS or replacing the OS hard disk.
