Such as the fine year of the next month 2 Kaiguo ^ the brain (four) 'name of the "switchable operating system shouting brain system" invention patent, = brain and an expansion device: the ribbon type computer contains a display device, when the portable computer is not When connected to the expansion device, when the It === flap type computer is connected to the expansion device, the second operating system is loaded into the second operating system, and is stopped, by the application modification or by the external expansion device. It is inconvenient to switch the operating system. Therefore, it is necessary to provide a method for switching the operating system by using a hot key. By writing a command in the dirty, the user can press the self-set hot key to enable the BI0S to automatically modify the main boot record (MBR, m^ Rbootrecord) ^ 糸 system. [Summary of the Invention] The above content is necessary to provide a method for switching the operating system by using a hot key during the power-on self-test of the s, to achieve fast switching of the operating system, and also for the production of the system and Start the backup system of the compromised system. The preferred embodiment of the present invention provides a method for switching the operating system of the job key, and the hot key of the history can be quickly switched. The 総 includes the steps of the town: MM performs the daily self-test 1316681 (P〇ST) 'displays the prompt information of various user settings or system default hot keys; the BIOS uses Intl9 (an interrupt command) to determine whether the user presses the preset Hotkey; if it is confirmed that a preset hotkey has been pressed, the system will detect whether it is connected to the hard disk drive; if it is not connected to the hard disk drive, the process ends; if it is confirmed that it is connected to the hard disk drive, The command in BI〇s has been written, so that BI〇s automatically modifies the hard disk partition table in the main boot record', that is, the partition parameter of the operating system corresponding to the hotkey is modified; after the modification, the BIOS self-test is returned; BI0S The master boot record will be loaded after executing its own program; the parameter 'hard disk master boot bootloader retrieves the operating system corresponding to the hotkey pressed by the user' and starts the operating system. If the user presses the non-preset hotkey, the BIOS performs a self-test and starts the internal operation system. This implementation method can also be used to initiate a backup system for a compromised operating system. According to the conventional technology of the parent vehicle, the method for switching the operating system by using the hot key is to realize fast switching of the operating system by using a preset hot key during the power-on self-test of the BI0S, and the method It can also be used in the production of multi-boot systems and to boot backup systems for damaged systems. [Embodiment] Referring to the first figure, a schematic diagram of a hard disk structure of a computer in a preferred embodiment of the present invention is shown. The computer generally includes a basic input/output system (BIOS ' BasicInput/Output System), hard disk 1 and memory. The hard disk 1 is composed of a plurality of platters, each of which has a read/write head (Heads), and the heads are sequentially numbered from 〇, χ, 2; each disc Concentric circles with a fixed radius r form a cylinder (Cylinders) with the motor spindle as the axis, starting from the outside to the inside with 〇, 1, 2; each track on each disc It is divided into dozens of magnetic regions (Sect〇r), and the usual capacity is 512 bytes, which are numbered starting from according to certain rules. Thus, the cylinders X heads are formed. These three parameters are the physical parameters of the hard disk. The main boot record (MBR, Master Boot Record) is located at the zeroth cylinder of the entire hard disk and the first magnetic region of the zeroth magnetic head, and mainly stores the hard disk master booting program. 111 and Disk Partition Table (DPT) 110. When the computer is powered on, the BIOS will control the system to the master boot record η after executing its own program. The hard disk master boot program lu stored in the master boot record 11 will retrieve the hard disk partition. In the boot partition 'in order to boot. The hard disk partition table 110 is used to record the partition information of the hard disk. The first disk partition 12 and the second disk partition 13 are boot partitions in the computer system, and have a first operating system 120 and a second operating system 130. The first operating system 120 and the second operating system 130 are various types of operating systems installed by the user according to personal preferences, such as various types of Windows operating systems of Microsoft Corporation, or a backup of one of the operating systems. In addition to the first disk partition 12 and the second disk partition 13, a plurality of disk partitions may be set in the boot partition in the computer system and a corresponding operating system may be stored, and the master boot may be modified. Recording U makes one of the partitions a hidden partition, which is convenient for protecting the operating system stored in the partition. The partition in which each operating system is located can be represented by three parameters: Cylinders X Heads X Sector - and these data are stored in the hard disk partition table U〇.
