Embodiment Construction

[0018] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] reference figure 1 The present invention provides a computer operating system startup method, which includes the following steps: powering on the computer; BIOS requests the hard disk to read the MBR boot program through the control hardware; the control hardware intercepts the MBR boot program from the hard disk, and The predetermined control program is transmitted to the computer mainboard; the computer mainboard executes the predetermined control program and authenticates the user of the computer. When the user passes the identity authentication, the computer mainboard sends a verification instruction to the control hardware; When the control hardware receives the verification pass instruction, it sends the MBR boot program intercepted from the hard disk to the computer; the computer motherboard reads the MBR boot program and guides...

Abstract

The invention provides a computer operating system starting method. The computer operating system starting method includes that: a computer is powered; a request is sent to a hard disk to read an MBR (master boot record) bootstrap program via control hardware by a BIOS (basic input/output system); the MBR bootstrap problem is captured from the hard disk by the control hardware, and a scheduled control program is transmitted to a computer mainboard; the scheduled control program is executed by the computer mainboard, identity of a user of the computer is authenticated, and an authentication pass instruction is sent to the control hardware by the computer mainboard when the user passes the identity authentication; the MBR bootstrap program captured from the hard disk is sent to the computer when the control hardware receives the authentication pass instruction; the MBR bootstrap problem is read by the computer mainboard, and an operating system on the hard disk is booted to start. Since the control hardware is not related to the specific computer mainboard and the operating system, customization of a special mainboard is not required, good compatibility is provided, starting of a slave disk is controlled effectively, and safe starting of the computer operating system is guaranteed.

Description

Technical field [0001] The invention relates to a method for starting a computer operating system. Background technique [0002] The hard disk is the data carrier of the computer operating system, and the operating system is generally installed in the hard disk. When the computer operating system is started, the following steps are generally performed: load and start the main boot sector (MBR) of the hard disk through the basic input output system (BIOS), usually located in the first sector of the hard disk, which can store a small program and the main The boot program in the partition table; the MBR boot program scans all partition tables to find the active partition; the MBR boot program loads and starts the boot program saved in the partition boot area (PBR) of the active partition; the boot program in the active partition PBR Load and start the operating system installed on it. If the computer CPU boots the operating system stored in the hard disk to the computer memory thr...
