Reading method for boot sequence of computer boot equipment

Abstract

The invention relates to a reading method for a boot sequence of computer boot equipment, which is applied to a computer which is provided with a plurality of sets of computer boot equipment. The method is characterized in that a fixed address space is defined in a memory of the computer; subsequently, a BIOS (Basic Input Output System) memory is used for establishing a BIOS boot specification (BBS for short) table in the fixed address space of the memory in the process of executing the procedure of a boot built-in test; default boot sequence codes of the boot equipment are recorded; practical boot sequence codes are generated and added to the BBS table in the process of the built-in test; and finally, a corresponding relationship between the practical boot sequence codes in the memory and the boot equipment is read for displaying practical boot sequence information.

Description

technical field [0001] The invention relates to a computer startup technology, more specifically, to a method for reading the startup sequence of a computer startup device. Background technique [0002] A single computer device can be connected to many external storage devices, such as floppy disks, U disks, optical discs, hard disks, or network cards, etc., and each of these storage devices can be used as a boot device to guide the computer device with the help of the boot program stored in each of the storage devices. Load the operating system. While a single computer device may be connected to multiple types of boot devices at the same time, the computer device's Complementary Metal-Oxide Semiconductor Random Access Memory (Complementary Metal-Oxide Semiconductor Random Access Memory, CMOS RAM) stores information about different types of boot devices accordingly. The related information of the boot order (boot order) of the system can prevent the system from loading the ...

Problems solved by technology

[0004] Apparently, it is extremely cumbersome to perform the startup sequence checking operation through the above operation method, and the user must hold down the del key or the F2 key at the moment of starting the machine. Press and hold the del key or F2 key at the beginning, no matter how much you press the key, the computer device will not be able to enter the CMOS setting interface. In addition, there are many other important system configuration parameters stored in the CMOS setting interface. The setting of other parameters of the system will affect the normal operation of the system
