Detailed ways

The following embodiment of the computer booting method is executed in a computer device, and can selectively load two operating systems with different file systems for booting without requiring two partitions.

As shown in FIG. 1 , the processor 1 is coupled to a main memory 2 and storage devices 4 and 5 . The first operating system 70 is installed in the partition 51 of the storage device 5 . The first operating system 70 supports a first file system. Partition 51 is formatted with the first file system. The storage device 5 can be a hard disk drive or other storage media. When the computer storage device 10 is turned on, it can automatically load and execute the first operating system 70 .

The storage device 4 includes a second operating system 71 , a bootloader 72 and an installer 73 for installing the second operating system 71 to the partition 51 . The above-mentioned second operating system includes a kernel program (Kernel) 711 and a library 712, and supports a second file system different from the above-mentioned first file system. The core program 711 and the function library 712 can be compressed into a core program compressed file and a virtual disk file (RamDisk file) respectively in advance. It should be noted that the core program 711 and the function library 712 do not need to be compressed. The storage device 4 can be an optical disc, a disk, or other storage media. The installer 73 can be executed in the environment of the first operating system 70 . The format specification of the storage device 4 can conform to the first file system, and can store the second operating system 71 , the loading program 72 and the installation program 73 in the same format.

For example, the above-mentioned first file system is the file system (NT File System, NTFS for short) of Windows operating system NT of Microsoft Corporation, and the second operating system 71 is the Linux operating system. The Linux operating system has a virtual file system (virtual file system, referred to as vfs), which can support a variety of file systems, such as the second extended file system (the Second Extended file-system, referred to as ext2), NTFS, Network File System (the Network File -system, referred to as nfs), MS-DOS file allocation table file system (The MS-DOS File Allocation Table filesystem, referred to as FAT), and other file system read operations. The above-mentioned second file system may be the above-mentioned virtual file system.

Figure 2 shows a flowchart of a second embodiment of an operating system installation operation. After the computer device 10 is powered on with the first operating system 70, the processor 1 starts the installation program 73 using the first operating system 70 (step S2).

Using the installation program 73, the processor 1 uses the first file system to store the second operating system 71 in the partition 51 (step S4), as shown in FIG. 3 . For example, the processor 1 stores the compressed file of the second operating system 71 including the kernel program 711 and the library 712 in a predetermined directory of the partition 51 .

Using the above-mentioned installation program 73, the processor 1 stores a loading program 72 in the storage device 5 (step S6), which is used to load the core program 711 to the main memory 2 when the computer device 10 is turned on, as shown in FIG. 3 . For example, the storage device 5 is a hard disk drive, and the loading program 72 can be stored in the first magnetic area of the storage device 5, such as in the master boot magnetic area (Master Boot Record). If the original loading program already exists in the storage device 5, the loading program 72 can replace the original loading program or modify the original loading program, so that the core program 711 is loaded into the main memory 2 when the computer device 10 is turned on. Therefore, the loading program 72 needs to be capable of reading files in the above-mentioned first file system. The installation of the second operating system 71 is completed (step S8). At this time, different first operating systems 70 and second operating systems 71 are stored in the partition 51 of the storage device 5 , as shown in FIG. 3 .

FIG. 4 is a flowchart showing the computer device 10 booting and loading the second operating system 71 .

After the computer device 10 is powered on and executes the Power On Self Test (Step S20), the processor 1 executes the loading program 72. The processor 1 automatically detects the value of a register to determine whether to boot 71 with the second operating system (step S22). For example, the above-mentioned register reflects the state of an input key (such as a hot key (hot key) or function key (function key) of a keyboard or a remote controller), and when the computer device 10 is powered on, it is determined according to the state of the input key. Load the first operating system 70 or the second operating system 71 for booting. When the computer device 10 is powered on with the first operating system 70, the first operating system 70 is loaded into the main memory 2 (step S23). The computer device 10 enters a general computer operation mode (PC mode) (step S42).

When the computer device 10 is powered on with the second operating system 71, the loading program 72 obtains the core program 711 according to the predetermined directory (step S24). If the core program 711 is stored in the partition 51 in the form of a compressed file, the processor 1 needs to decompress the compressed file of the core program before loading it into the main memory 2 (step S26). The processor 1 loads the decompressed kernel program 711 from the partition 51 into the main memory 2, and starts to execute the kernel program 711 (step S28).

According to the kernel program 711, the processor 1 creates a part of the main memory 2 as a virtual disk (RAMdisk) 21, and its formatting specification conforms to the above-mentioned second file system (step S32). For example, the processor 1 establishes a directory as a mount point according to the core program 711, establishes the above-mentioned second file system (formats the virtual disk 21 with the specification of the above-mentioned second file system), and stores the second file system Mount it in the above directory. For example, the above-mentioned first file system is a file system (NT File System, NTFS) of a software company's Windows operating system, and the kernel program 711 is a kernel program of a Linux operating system that can support multiple file systems. The kernel program 711 can support the above-mentioned file reading operation of the first file system, and the above-mentioned operation of creating the virtual disk 21, and create the virtual disk 21 as an ext2 file system.

According to the core program 711, the processor 1 obtains the virtual disk compressed file in the predetermined directory (step S34), and decompresses the library 712 (step S36).

The processor 1 loads the second operating system 71, including the decompressed library 712, from the above-mentioned first file system of the partition 51 into the virtual disk 21 (step S38). Since the second operating system 71 supports the second file system, the second operating system 71 can normally read and write data, add and delete files, execute application programs and access the library 712 in the operating environment of the virtual disk 21 . At this point, the booting operation using the second operating system 71 has been completed, and the computer device 10 executes the second operating system 71, for example, enters the operation mode (AV mode) of an audio-visual appliance (step S40).

The above-mentioned computer booting method can be implemented by using a computer program. The above-mentioned computer program is stored in a computer-readable storage medium for executing the above-mentioned steps.

As shown in FIG. 5 , the storage medium 60 is used to store a computer program 620 for implementing a computer boot method. The computer program includes four logics, which are installation logic 621 , loading logic 622 , operating system core logic 623 , and operating system library logic 624 .

The installation logic 621 is used to install the loading logic 622 into a storage device, and store the operating system core logic 623 and the operating system library logic 624 in a partition of the storage device, wherein another partition has been installed operating system and formatted with the file system of another operating system. The loading logic 622 is used for loading the operating system kernel logic 623 into a main memory. The operating system core logic 623 is used to create a part of the main memory as a virtual disk and load the operating system library logic 624 . The formatting of the above-mentioned virtual disk is different from the above-mentioned partition.

Using the main memory 2 to establish the second file system of the virtual disk 21 allows the computer device to load the second operating system 71 from the partition 15 to boot without occupying another partition. Therefore, the above-mentioned computer booting method allows the computer device to use the same partition in its storage device when booting, but each supports different file systems for booting.
