detailed description

The following will clearly illustrate the spirit of the present invention with the accompanying drawings and detailed descriptions. After any person with ordinary knowledge in the art understands the preferred embodiments of the present invention, he can change and modify it by the technology taught in the present invention. without departing from the spirit and scope of the present invention.

Please refer to FIG. 1 , which is a flowchart of an operating system processing method according to an embodiment of the present invention. In the operating system processing method, according to the data of the specific address on the master boot record sector of the host computer, it is judged whether the characteristic value of the current operating system version matches the characteristic value of the image file used for installation, as the basis for whether to install the operating system . The operating system processing method is implemented through a host and a computer program, and the computer program can be stored in a computer-readable recording medium, so that the host executes the operating system processing method after reading the recording medium. The computer-readable recording medium can be read-only memory, flash memory, floppy disk, hard disk, optical disk, pen drive, magnetic tape, database accessible by the network, or a computer-readable recording medium having the same function can be easily conceived by those skilled in the art . When the program code is loaded and executed by the host, the host becomes a system for participating in the present invention. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique device that operates similarly to application-specific logic circuits.

The operating system processing method 100 is applied to a host. Wherein, the host includes a master boot record sector. The applied host can be a physical host or a virtual host. Wherein, when the host is a virtual host, the virtual host will also have a virtual host operating system, a boot priority of the virtual host, a boot reading device, and the like. The operating system processing method 100 includes the following steps:

When the host is powered on (step 110), a boot loader (bootloader) is read from a boot reading device of the host according to a boot priority of the host (step 120). Wherein, the boot loader includes a default version feature value. In addition, by changing the boot priority setting in the basic input/output system (BIOS), different reading devices can be set as the boot reading devices. Generally speaking, the reading device set as the first order in the booting priority is the booting reading device. For example, a flash memory, a floppy disk, a hard disk, an optical disk, a flash drive, a magnetic tape, a remote server that can be accessed through the network, or a reader device that can be easily imagined by those skilled in the art to have the same function can be set as a bootable read device. Thus, the boot loader can be stored or loaded into the set boot reading device for reading in step 120 . In addition, an operating system image file of an operating system to be installed can also be stored or loaded into the set boot-reading device.

In step 130 , a feature detection program in the boot loader is executed to detect data at a specific address of the master boot record sector of the host. Wherein, the data of the specific address corresponds to a characteristic value of a current version of the host. Therefore, in step 140, it can be judged according to the data of the specific address whether the characteristic value of the current version matches the characteristic value of the preset version (step 140). In an embodiment of the present invention, the data at the specific address can be the characteristic value of the current version, and step 140 is to judge whether the data at the specific address (the characteristic value of the current version) is equal to the characteristic value of the preset version to determine whether they match. Wherein, the 444th byte or the 445th byte on the master boot record sector can be used as the preset position, so as to prevent the master boot record sector from being regarded as damaged by the host or overwritten by other information of the host. In another embodiment of the present invention, the data at a specific address can be a storage location of the current version characteristic value in the host, and in step 130, the data at the storage location can be read as the current version according to the data at the specific address. The characteristic value is used for step 140 to judge. In this way, the characteristic value of the current version can be stored in other locations (such as a specific file, a specific location on the operating system of the host computer, or a specific sector on the storage device of the host computer), so as to avoid the storage space required by the characteristic value of the current version from being too large. Too large to be stored in the master boot record sector.

When the characteristic value of the current version matches the characteristic value of the preset version, the host can be enabled to enter the operating system (step 180).

In step 150, when the characteristic value of the current version does not match the characteristic value of the preset version, an operating system image file is read from the boot reading device of the host computer, and an operating system to be installed is installed on the host computer according to the operating system image file , as the host's current operating system.

In step 160 , modify the data of the specific address of the master boot record sector according to the feature value of an image file version of the operating system to be installed, so as to correspond to the feature value of the current version of the operating system installed in step 150 . For example, when the data at the specific address of the master boot record sector is the version feature value of the currently installed operating system, the version feature value of the image file version of the operating system to be installed can be written into the specific address of the master boot record sector as the current version feature value. When the data at the specific address is a storage location of the current version feature value in the host, the image file version feature value of the operating system to be installed can be written into another storage location and then another storage location can be written into the main boot Record the specific address of the sector, or write the characteristic value of the image file version of the operating system to be installed into the original storage location, so as to modify the current version characteristic value of the original storage location.

Furthermore, after step 160, the host computer can be restarted, so that the host computer can execute the installed current operating system. In this way, the operating system to be installed or the operating system to be installed can be installed or updated on the host only by pre-storing or loading the boot loader and the operating system image file of the operating system to be installed on the boot-reading device set on the host Version. And no matter whether any operating system has been installed on the host, it can be installed by using the present invention. In a preferred embodiment of the present invention, the boot priority of the host can be set to boot from the network, and when the boot read device of the host is a remote server on the network, the present invention only needs to store the boot on the remote server. The loader and the operating system image file can remotely install the operating system to be installed on the host, without manual operation by the user or going to the location where the host is installed to perform the installation operation. Therefore, in an application scenario of the present invention, the user can simultaneously install the operating systems of multiple hosts without manual operation.

In an embodiment of the present invention, in step 140, when it is determined that the data at the specific address does not match the preset version characteristic value, the version characteristic value of the image file is further read to determine whether an update is required. When it is determined that an update is required, the current operating system of the host is updated according to the operating system image file, and the data at a specific address of the master boot record sector is modified according to the version feature value of the image file to correspond to the current version feature value. The host can then execute the updated operating system. In this way, the operating system on the host can be installed or updated only by pre-storing or loading the boot loader and the operating system image file of the operating system to be installed on the boot reading device set on the host.

In addition, in another embodiment of the present invention, in step 140, when it is determined that the data at the specific address does not match the characteristic value of the preset version, it is further determined whether the data at the specific address is smaller than the characteristic value of the preset version. In this embodiment, the characteristic value of the newer version is set to a larger value, that is, when the version is updated, its characteristic value will become larger. Therefore, when the data at the specific address is smaller than the characteristic value of the preset version, according to the operating system image file, the operating system to be installed is installed on the host as the current operating system of the host. Then, modify the data at the specific address of the master boot record sector according to the feature value of the image file version, so as to update and correspond to the feature value of the current version.

In yet another embodiment of the present invention, the characteristic value of the current version can be generated through a debugging method. Therefore, by means of error detection, it can be judged whether the characteristic value of a current version of the host corresponding to the data of the specific address is correct, as a basis for judging whether the characteristic value of the current version matches the characteristic value of the preset version. In an embodiment of the present invention, the error detection method may be Cyclic Redundancy Check (CRC) or other bit error detection methods. Therefore, the corresponding error detection method can be used to determine whether the data at the specific address is correct. In another embodiment of the present invention, the version feature values of the released versions of the operating system may be pre-stored as a basis for judging whether the data at a specific address is correct. However, in other embodiments of the present invention, the determination can be made in other ways, which is not limited to the present disclosure.

Therefore, when the judgment is incorrect, the operating system to be installed can be installed on the host computer as the current operating system of the host computer according to the operating system image file. For example, when the data at the specific address of the master boot record sector is the characteristic value of the current version, it is judged whether the data at the specific address is correct through an error detection method; when the data at the specific address of the master boot record sector is a storage location, read according to the storage location Get the data (that is, the characteristic value of the current version), and then judge whether it is correct through the error detection method. Then, modify the data at the specific address of the master boot record sector according to the image file version characteristic value, so as to update the characteristic value corresponding to the current version. Next, the host can be restarted, so that the host can execute the current operating system after installation. This allows the operating system on the host to be reinstalled if the data at a particular address is incorrect. In particular, in an application scenario of the present invention, if the host is infected by a boot-type virus and its master boot record sector is modified, the above-mentioned verification process can be used to allow the host to reinstall an operating system that is not infected by the virus.

Please refer to FIG. 2 , which is a functional block diagram of a processing system of an operating system according to an embodiment of the present invention. The processing system of the operating system judges whether the characteristic value of the current operating system version matches the characteristic value of the image file used for installation according to the data of the specific address on the master boot record sector, as the basis for whether to install the operating system.

The operating system processing system 200 is set on a host. The operating system processing system 200 includes a boot readout device 210 , a storage component 220 and a processing component 230 . The processing component 230 is communicatively connected to the boot reading device 210 and the storage component 220 . In an embodiment of the present invention, the boot reading device 210 and the storage component 220 can be electrically connected to the processing component 230 respectively, so that the processing component 230 can communicate with the boot reading device 210 and the storage component 220 . In another embodiment of the present invention, the processing component 230 can communicate with the boot readout device 210 and the storage component 220 through a network. However, in other embodiments, the processing component 230 can communicate with the boot reading device 210 and the storage component 220 in other ways, and the boot reading device 210 and the storage component 220 can also communicate with the processing component 230 in different ways. , is not limited to this example.

The boot readout device 210 can be a flash memory, a floppy disk, a hard disk, an optical disk, a flash drive, a magnetic tape, a remote server accessible through the network, or a readout device with the same function that those skilled in the art can easily think of. When the host is powered on, the boot reading device 210 reads a boot loader according to the boot priority of the host. The boot loader contains a default version signature. The storage component 220 includes a master boot record sector.

The processing component 230 includes a booting module 231 , a judging module 232 and a characteristic value modifying module 234 . The boot module 231 executes a feature value detection program in the boot loader to detect data at a specific address of the master boot record sector of the storage device. The data at the specific address corresponds to a feature value of a current version of the host. Wherein, the boot-up reading device 210 can be set as a priority reading device after boot-up by changing the boot-up priority setting in the host computer's BIOS. Therefore, the boot loader can be stored or loaded into the boot reading device 210, so that the boot module 231 can be preferentially read when the host is powered on. In addition, an operating system image file of an operating system to be installed can also be stored or loaded into the boot reading device 210 .

The judging module 232 judges whether the characteristic value of the current version matches the characteristic value of the preset version according to the data of the specific address of the storage component 220 . When the judging module 232 determines that it does not match, it reads an operating system image file from the boot reading device 210 of the host, and installs an operating system to be installed on the host according to the operating system image file as the current operating system of the host. The characteristic value modification module 234 modifies the data of the specific address of the master boot record sector according to the characteristic value of the image file version of the operating system to be installed to correspond to the characteristic value of the current version. For example, when the data at the specific address of the master boot record sector is the feature value of the version of the currently installed operating system, the feature value modification module 234 can write the feature value of an image file version of the operating system to be installed into the master boot record of the storage component 220 The specific address of the sector, as the characteristic value of the current version. When the data at the specific address is a storage location of the current version feature value in the host, the feature value modification module 234 can write the image file version feature value of the operating system to be installed into another storage location and then store another The location is written to the specific address of the master boot record sector of the storage component 220, or the characteristic value modification module 234 can write the characteristic value of the image file version of the operating system to be installed into the original storage location, so as to modify the current version characteristics of the original storage location value.

Furthermore, the processing component 230 can reboot the host, so that the host can execute the installed current operating system. In this way, the operating system can be installed on the host only by pre-storing or loading the boot loader and the operating system image file of the operating system to be installed on the boot reading device 210 of the processing system 200 . In a preferred embodiment of the present invention, the boot priority of the host computer can be set to boot from the network, and when the boot read device 210 of the host computer is a remote server on the network, the present invention only needs to store the The boot loader and the operating system image file can remotely install the operating system to be installed on the host, without manual operation by the user or going to the location where the host is installed to perform the installation operation.

Please refer to FIG. 3 , which is a functional block diagram of a computer host according to another embodiment of the present invention. It should be understood that in the following description, the content that has been described in the above embodiments will not be repeated.

The processing system 200 may support an operating system update function. Therefore, the processing component 230 may further include an update module 236 . When the data at the specific address does not match the preset version characteristic value, the update module 236 can further read the image file version characteristic value of the operating system image file to determine whether to update. When the update module 236 determines that an update is required, the current operating system of the host is updated according to the operating system image file. In addition, the characteristic value modifying module 234 modifies the data of the specific address of the master boot record sector of the storage component 220 according to the characteristic value of the image file version to correspond to the characteristic value of the current version. In this way, the operating system of the host can be updated only by pre-storing or loading the boot loader and the operating system image file of the operating system to be installed on the boot reading device 210 . In particular, in one embodiment of the present invention, when the boot-reading device 210 of the processing system 200 is a remote server on the network, only the boot loader and the operating system image file need to be stored in the remote server without manual operation by the user. The operating system update is now complete.

In another embodiment, the characteristic value of the current version may be generated through a debugging method, and the processing component 230 may further include a debugging module 237 . The error detection module 237 judges whether a current version characteristic value of the host computer corresponding to the data of a specific address is correct by means of error detection, as a basis for judging whether the current version characteristic value matches the preset version characteristic value. When the determination is incorrect, the processing component 230 installs the operating system to be installed on the host as the current operating system of the host according to the operating system image file. In addition, the characteristic value modifying module 234 modifies the data of the specific address of the master boot record sector according to the characteristic value of the image file version to correspond to the characteristic value of the current version. Next, the host can be restarted, so that the host can execute the reinstalled current operating system. This allows the operating system on the host to be reinstalled if the data at a particular address is incorrect. In particular, in an application scenario of the present invention, if the host is infected by a boot-type virus and its master boot record sector is modified, the above-mentioned error detection process can be used to enable the host to reinstall an operating system that is not infected by the virus.

In addition, the judging module 232 may include a reader 232a. The reader 232a can read data at a specific address on the master boot record sector of the storage device 220 . Wherein, the 444th byte or the 445th byte on the master boot record sector of the storage component 220 can be used as the above-mentioned preset position, so as to prevent the master boot record sector from being regarded as damaged by the host or overwritten by other information of the host . In another embodiment of the present invention, the data at the specific address is a storage location of the current version characteristic value in the storage component 220 . Therefore, the reader 232a can read the data in the above-mentioned storage location as the characteristic value of the current version for the judging module 232 to judge. In this way, other locations on the storage component 220 (such as a specific file, a specific location on the operating system of the host computer, or a specific sector on the storage component 220) can be used to store the current version characteristic value, thereby avoiding the current version characteristic value. The required storage space is too large to be stored in the master boot record sector.

Although the present invention has been disclosed above in terms of implementation, it is not intended to limit the present invention. Any skilled person can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of protection should be based on the scope defined by the appended claims.
