detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to FIG. 1 . FIG. 1 is a flow chart of a method for starting dual hard disks and dual systems provided by an embodiment of the present invention. The method can include:

Step 101: after the motherboard is powered on, read the value of the preset CMOS register in the BDS stage of Bios boot; wherein, the default value of the CMOS register is 0.

It can be understood that the purpose of this step can be to use the value of the CMOS register on the main board to select the corresponding first minimized system or the second minimized system to start. For the specific selection of the CMOS register and the setting of the value, it can be determined by design The staff can set it according to the practical scenario and user needs. For example, you can choose an idle CMOS register with a default value of 0 in CMOS 0x62, which only stores two values of 0 (low) or 1 (high), or you can choose other values that can store more values. register, as long as the value of the register can be used to select the corresponding first minimized system or the second minimized system to start, this embodiment is not subject to any limitation.

Correspondingly, the method provided by this embodiment can use the value read to the CMOS register to select the first minimization system or the second minimization system corresponding to the value, since the method provided by this embodiment is based on dual hard disks Dual systems are taken as an example. Therefore, only one CMOS register that stores two values of 0 (low) or 1 (high) can achieve the above-mentioned purpose; One register or multiple registers that store more values are used, and this embodiment is not limited in any way.

It should be noted that, in the method provided in this embodiment, interfaces of the first preset hard disk and the second preset hard disk may be provided on the motherboard, and the first minimization system and the second minimization system are respectively pre-installed on the first on the default hard disk and on the second default hard disk. For the specific types of the first preset hard disk and the second preset hard disk, they can both be SSD disks (solid-state hard disks); they can also be other hard disks such as mechanical hard disks; subject to any restrictions. Similarly, the specific types of the first minimized system and the second minimized system may be the same Linux system or other systems, or may be two different systems, which are not limited in this embodiment.

Step 102: If the value of the CMOS register is 0, set the value of the CMOS register to 1, and load the first minimized system stored in the first preset hard disk.

Wherein, setting the value of the CMOS register to 1 in this step can enter step 103 to start the second minimized system after the motherboard restarts when the first minimized system cannot be started.

It can be understood that if the first minimized system stored in the first preset hard disk cannot be started after loading the first minimized system, the mainboard can be restarted by the user or automatically, so as to enter step 103 through step 101 and start Second minimization system. As for the specific manner of restarting the mainboard, it may be to restart the mainboard according to receiving an instruction sent by the user; it may also be to automatically restart the mainboard after it is determined that the first minimized system cannot be started. This embodiment is not limited in any way.

Preferably, for the convenience of the user, after it is determined that the first minimized system cannot be started, the mainboard can be automatically restarted. That is to say, the method provided by this embodiment may also include: setting the preset GPIO value to 0; detecting whether the GPIO value is 1 within the preset time interval; if the GPIO value within the preset time interval is not 1, then restart the mainboard steps. And correspondingly, after the first minimized system or the second minimized system is started, the step of setting the value of GPIO to 1. Whether the first minimized system or the second minimized system is started successfully is determined by using a preset GPIO value, so that when the first minimized system or the second minimized system cannot be started, the motherboard is restarted.

Specifically, the specific method and process for detecting whether the value of GPIO is 1 within the preset time interval can be set by the designer according to practical scenarios and user needs, such as using CPLD (Complex Programmable Logic Device, complex programmable logic device) The watchdog detects the value of GPIO, and detects once every 5 minutes. The number of detections is set to 6, that is, the value of GPIO is not 1 within the preset time interval of 30 minutes, and the first minimum system or the second minimum system is determined. If the system cannot be started, you can pull down slp_S3 to restart the motherboard. This embodiment is not limited in any way. Similarly, as for the specific method of restarting the mainboard, the mainboard can be restarted by pulling down slp_S3, or by other methods, which is not limited in this embodiment.

Step 103: If the value of the CMOS register is 1, load the second minimized system stored in the second preset hard disk.

Wherein, the specific way of loading the second minimized system stored in the second preset hard disk in this step can be set by the designer himself, such as changing the startup sequence, as shown in Figure 2, if the value of the CMOS register is 1, then The priorities of the first default hard disk (HDD1) and the second default hard disk (HDD2) can be exchanged during this startup, and the second minimized system is loaded from the second default hard disk. As long as the second minimized system stored in the second preset hard disk can be loaded when the value of the CMOS register is 1, this embodiment does not impose any limitation on this.

It can be understood that, in order to further improve the system stability of the method provided by this embodiment and realize automatic system backup and repair, the minimized system that can be started at one time can be backed up to the hard disk storing another minimized system, and the other minimized system can be backed up. Deleting a minimized system means replacing another minimized system, so that the minimized systems stored in the two hard disks are all minimized systems that can be started at one time. That is to say, this step may also include: after the first minimized system is started, detecting whether the first minimized system started is loaded and started for the first time; if the first minimized system started is loaded and started for the first time, Then back up the first minimized system to the second preset hard disk, delete the second minimized system, and use the backed up first minimized system as the new second minimized system; when the second minimized system starts, Detect whether the second minimized system started is loaded and started for the first time; if the second minimized system started is loaded and started for the first time, then the second minimized system is backed up to the first preset hard disk, and the first The minimized system is deleted, and the backup second minimized system is used as the new first minimized system.

It should be noted that detecting whether the first minimized system or the second minimized system is started by loading for the first time may be to detect whether the first minimized system or the second minimized system can be loaded and started directly at one time, that is, Detect whether the performance of the first minimized system or the second minimized system has no problem, thereby backing up the minimized system with no problem to the hard disk storing another minimized system, so as to realize automatic backup and repair of the storage system.

Specifically, for detecting whether the first minimized system or the second minimized system is the specific detection time point for the first loading start, it may be performed directly after the first minimized system or the second minimized system is started. The step is, for example, a step of setting the value of the GPIO to 1; it may also be a step performed when the value of the GPIO is 1 within a preset time interval. This embodiment is not limited in any way.

Further, the method provided by this embodiment may also include the step of setting the value of the CMOS register to 0 after the first minimized system or the second minimized system is started, so that the minimized system is preferentially started from the first minimized system each time. The first minimized system stored in the preset hard disk is started; it may also be a step of setting the value of the CMOS register to 0 after the second minimized system is started. This embodiment is not limited in any way.

In this embodiment, the embodiment of the present invention reads the value of the preset CMOS register in the BDS stage of Bios boot after the main board is powered on and started, and the corresponding minimized system can be selected to start after the main board is turned on or restarted; If the value of the CMOS register is set to 1, when the first minimized system stored in the first preset hard disk cannot be started, the second minimized system stored in the second preset hard disk can be selected to start after the motherboard is restarted, so that not only can Resist the problem that the system cannot be booted due to the damage of the system file, and also avoid the problem of system disk failure caused by the link damage of one of the hard disks, and improve the stability of the system.
