Description

boot method

technical field

The present invention relates to a booting method, in particular to a method for displaying a first booting icon during a booting stage.

Background technique

With the development of information technology, electronic devices based on processors, such as various computers (Computers, also known as computers) have been widely used by enterprises and individuals. The general computer boot procedure is as follows. After turning on the power, the computer first performs the Power On Self Test (POST). The computer loads the Basic Input/Output System (BIOS) to determine the most basic hardware architecture and perform necessary initialization operations on the hardware. The BIOS then executes a boot loader (Boot Loader), and loads a boot program, such as a core program of an operating system of a computer, according to a boot device sequence (also called a boot order). After the startup program is loaded, the control right of the computer is handed over to the startup program to complete the booting operation of the entire computer.

The aforementioned boot device refers to a hardware device that may store a boot program inside, such as a hard disk, an optical drive, or a flash device. The boot device sequence is a sequence obtained by at least one boot pointer pointing to at least one boot device and arranged according to priority. According to the boot device sequence, the BIOS searches for the startup program in each boot device in order to load and start the computer. The boot device sequence allows the user to freely change the settings. The user can enter the setup menu (setup menu) to change the settings by pressing a hotkey (such as the F2 key on the keyboard) when the computer system is booting to execute the BIOS.

However, when executing the BIOS, the time for the user to enter the setting menu is not only very short, but also difficult to grasp the timing. In order to enter the setting menu to change the boot device sequence, the user may repeatedly press the preset hotkey after turning on the power, wasting a lot of unnecessary effort. In addition, the user cannot know the content of the boot device sequence except for entering the setting menu. Therefore, even if the user only wants to confirm the boot device sequence at that time, he must enter the setting menu to confirm when booting, which is very inconvenient. After entering the setting menu, no matter whether the boot device sequence is changed or not, the computer will usually restart again, which is also a waste of time.

Contents of the invention

In view of the above problems, the purpose of the present invention is to provide a boot method that can display a first boot icon when the BIOS is executed, so that the user can easily know the boot device that is set as the first priority when booting. . At the same time, the user can easily change a first boot indicator pointing to the first boot device by pressing a hot key before the boot program is loaded and executed.

The invention provides a booting method, which is suitable for a computer. The computer has a BIOS memory, a random access memory and a display device, and the BIOS memory has a BIOS. The BIOS accesses a boot device sequence, and the boot device sequence has a first boot index. The booting method includes: initializing random access memory; reading boot device sequence; initializing a video graphics array; loading a first boot icon into random access memory; The first boot icon is displayed on the display device; according to the sequence of the boot device, a startup program is loaded; and according to the startup program, the computer is started. The first boot icon is stored in the BIOS memory and corresponds to the first boot indicator.

According to the present invention, after the first boot icon stored in the random access memory is displayed on the display device by the video graphics array, and before loading a boot program according to the boot device sequence, it may further include: initializing an input device, the input device Used to receive an instruction input by a user; initialize an interrupt, the interrupt includes a setting program; judge whether the instruction is input; when the instruction is input, judge whether the instruction is a predetermined value; and when the instruction is the predetermined value , to execute the setup program.

The above-mentioned setting procedure may include: changing the first boot indicator according to a predetermined value; changing the first boot icon according to the changed first boot pointer, and loading the changed first boot icon into the random access memory; and borrowing Displaying the modified first boot icon stored in the random access memory on the display device by the video graphics array

According to an embodiment of the present invention, the BIOS memory can be a read-only memory, and the boot device sequence is stored in a complementary metal oxide layer conductor memory. The above-mentioned first boot icon can be a bitmap, the input device can be a keyboard, and the startup program can be an operating system.

In addition, according to the boot device sequence, the step of loading the first boot icon into the random access memory may further include: decompressing the first boot icon; and loading the decompressed first boot icon into the random access memory.

Detailed ways

The detailed features and advantages of the present invention described below are sufficient to enable any person familiar with the relevant art to understand the technical content of the present invention and implement it accordingly. Those skilled in the art can easily understand the related objects and advantages of the present invention.

Please refer to FIG. 1 , which is a schematic structural diagram of a computer according to the present invention. The computer 20 includes a processor 30, a BIOS memory 50, a random access memory (Random Access Memory, RAM) 40, a video graphics array (Video Graphics Array, VGA) 42, a display device 44 and at least one boot device 46. The BIOS memory stores a BIOS 52 , a boot device sequence 54 , a first boot icon 56 and a first boot indicator 58 .

The processor 30 may be a central processing unit (Central Processing Unit, CPU), for processing the calculation of the computer 20. After the computer 20 is powered on, the processor 30 performs a power-on self-test (POST) and loads the BIOS 52 . The processor 30 then initializes the basic hardware of the computer 20 , such as the random access memory 40 , the video graphics array 42 and the display device 44 .

The random access memory 40 can directly exchange data with the processor 30 . Since the random access memory 40 can be read and written at any time and has a high speed, it will be initialized as early as possible in the boot process for subsequent use. During the booting process, the program codes stored in the BIOS memory 50 will also be copied to the random access memory 40 for execution.

The video graphics array 42 is a computer display standard using analog signals. General personal computers and other devices must support the video graphics array 42 standard before loading their own unique drivers. The video graphics array 42 usually uses fixed addressing locations between 0xA0000 and 0xC0000 in the random access memory 40 during startup. Although the resolution and the number of loaded colors are insufficient, the computer can display information on the display device 44 after the video graphics array 42 and the random access memory 40 are initialized.

The boot device 46 can be the basic hardware of the computer, or a peripheral device connected to the computer 20, or even a remote computer connected via a network. A startup program for completely starting the computer 20 can be stored in the boot device 46 . For example, the boot device 46 can be a hard disk, an optical drive or a flash device. The startup program may be, but not limited to, an operating system, or a core program of the operating system.

The BIOS memory 50 is usually a memory that will not lose data content even after a power failure, such as a read-only memory (Read Only Memory, ROM), or a read-only flash memory (flash memory). The program content of the BIOS 52 is stored in the BIOS memory 50 , and is used to control the program between the computer 20 being powered on and the computer 20 being fully activated by the activated program.

The boot device sequence 54 may have at least one boot target, and when there are multiple boot targets, these boot targets point to different boot devices 46 according to priorities. The sequence in the boot device sequence 54 can be a built-in sequence, and can also be changed by the user. In addition, the content of the boot device sequence 54 can be, for example, optical drive-hard disk-flash device.

The BIOS 52 accesses the boot device sequence 54 , and searches for a boot program in each boot device 46 according to the priority recorded in the boot pointer in the boot device sequence 54 , so as to load and start the computer 20 . The boot device sequence 54 has a first boot pointer 58 for pointing to the boot device 46 (ie, the first boot device) whose priority is set to be the first. When the processor 30 wants to load the startup program, it first searches for the startup program in the first boot device to load and execute it.

According to the present invention, the BIOS memory 50 can be but not limited to a read-only memory, and the boot device sequence can be stored in a Complementary Metal-Oxide-Semiconductor (CMOS), or other power-off Data will not disappear and non-read-only memory devices, such as flash memory. In addition, multiple boot icons can be stored in the BIOS memory 50, and each boot icon corresponds to and represents a boot device 46, such as a hard disk or an optical drive. The boot icon corresponding to the first boot device is called the first boot icon 56 . The format of the first boot icon 56 and other boot icons may be a bitmap (bitmap, also called BMP). By displaying the first boot icon 56 to the user, the user can know which boot device 46 is the currently set first boot device from the displayed first boot icon 56 .

Please refer to FIG. 2 , which is a schematic flowchart of booting up according to an embodiment of the present invention. As can be seen from the figure, the steps of booting with the display method of the boot device sequence include step S60: initializing the random access memory 40; step S70: reading the boot device sequence 54; step S80: initializing the video graphics array 42; step S90: The first boot icon 56 is loaded in the random access memory 40; step S100: display the first boot icon 56 stored in the random access memory 40 on the display device 44; step S180: load the startup program according to the boot device sequence 54; and steps S190: Start the computer 20.

In step S60, the random access memory 40 is initialized. Taking a general computer as an example, after the computer 20 is powered on, it will initialize the processor 30, the North bridge chip (North bridge, not shown), the random access memory 40, and the South bridge chip (South bridge, not shown) in sequence. After the random access memory 40 is initialized, the processor 30 can use the random access memory 40 to execute subsequent programs and calculations.

The processor 30 reads the boot device sequence 54 at step S70, and initializes the video graphics array 42 at step S80. Following the above-mentioned initialization sequence when the general computer is turned on, after the processor 30 initializes the south bridge chip, it continues to initialize the keyboard controller (Keyboard Controller, KBC) (not shown), the video graphics array 42 and the peripheral component interconnection (Peripheral Component Interconnect , PCI) device (not shown) and other hardware. After the video graphics array 42 is initialized, the display device 44 will display the data at addresses 0xA0000 to 0xC0000 in the random access memory 40 on the display device 44 . That is to say, if the user sees the screen after booting, it means that the video graphics array 42 has been initialized.

Then step S90 loads the first boot icon 56 corresponding to the first boot device into the random access memory 40 . Please also refer to FIG. 3 , which is a schematic flowchart of step S90 according to an embodiment of the present invention. According to the present invention, when loading the first boot icon 56 into the random access memory 40, it may further include step S92: decompressing the first boot icon 56; and step S94: loading the decompressed first boot icon 56 into the random access memory 40. Memory 40.

In order to save the space of the BIOS memory 50, the first boot icon 56 may be a graphic file stored in the BIOS memory 50 after being compressed. Then when wanting to load the first boot icon 56 into the random access memory 40, the compressed icons stored in the BIOS memory 50 must be decompressed and then loaded into the random access memory 40. The aforementioned steps S90 , S92 , and S94 are to decompress the compressed first boot icon 56 and then store it in the random access memory 40 at addressing locations 0xA0000 to 0xC0000. The video graphic array 42 usually fixedly uses the addressing position in the random access memory 40 when starting up to be between 0xA0000 and 0xC0000, so the first boot icon 56 can be loaded to the above address to wait to be displayed on the video graphic array 42. on the display device 44. In addition, the location where the first boot icon 56 is loaded into the random access memory 40 corresponds to the memory address used by the video graphics array 42 . According to the present invention, the loading location is not limited to address 0xA0000 to 0xC0000 in the random access memory 40 , but can be changed according to the setting of the video graphics array 42 .

After the first boot icon 56 is loaded into the random access memory 40 , the processor 30 displays the first boot icon 56 on the display device 44 in step S100 for user's reference. The processor 30 loads the first boot icon 56 into the random access memory 40 according to the first boot indicator 58 of the boot device sequence 54 , and makes the video graphics array 42 display the loaded first boot icon 56 . This allows the user to learn the content of the first boot indicator 58 from the displayed first boot icon 56 without entering the setting menu. Please refer to FIG. 4 , which is a schematic display diagram according to an embodiment of the present invention. As shown in the figure, the first boot icon 56 represents the boot device 46 pointed to by the first boot indicator 58 and is displayed on the display device 44 .

In step S180 , the processor 30 sequentially searches each boot device 46 for a boot program according to the boot device sequence 54 , so as to fully boot the computer 20 . When no usable startup program is found in the boot device 46 pointed to by the first boot pointer 58 , the processor 30 searches for the boot program in the second boot device 46 . If still can't find the startup program that can use, just continue to go to the startup device 46 of next order according to the startup device sequence 54 and look for.

After finding the startup program, the processor 30 loads the startup program in step S190, and transfers the control right of the computer 20 to the startup program from the BIOS 52, so as to complete the startup operation of the entire computer 20.

Please refer to FIG. 1 again. According to another embodiment of the present invention, the computer 20 may further include an input device 47 and an interrupt (Interrupt) 48 . The input device 47 is used to receive instructions input by the user, and the input device 47 may be but not limited to a keyboard. The interrupt 48 refers to a module that receives a signal from hardware or software other than the processor 30 and performs corresponding processing, and the interrupt 48 includes a setting program. The input device 47 may include at least one hotkey, and each hotkey is set to correspond to a booting device 46 . Each hotkey can trigger the setting program through the interrupt 48 to change the first boot indicator 58 to the boot device 46 corresponding to the hotkey.

Please refer to FIG. 5 , which is a schematic flowchart of booting up according to another embodiment of the present invention. Please refer to FIG. 2 and FIG. 5 at the same time, wherein the same reference numerals represent similar steps.

As can be seen from FIG. 5, the boot method includes step S60: initializing the random access memory 40; step S70: reading the boot device sequence 54; step S80: initializing the video graphic array 42; step S90: loading the first boot icon 56 on Random access memory 40; step S100: display the first boot icon 56 stored in random access memory 40 on display device 44; step S110: initialize input device 47; step S120: initialize interrupt 48; step S130: determine whether to command input; step S140: determine whether the command is a predetermined value; step S150: change the first boot indicator 58; step S160: change the first boot icon 56, and load the changed first boot icon 56 into the random access memory 40 ; Step S170: Display the modified first boot icon 56 stored in the random access memory 40 on the display device 44; Step S180: Load the startup program according to the boot device sequence 54; and Step S190: Start the computer 20.

The contents of step S60 to step S100 are roughly as described in the previous embodiment. In a general computer, after initializing the video graphics array 42 , step S110 is followed to initialize the keyboard (which can be regarded as one of the input devices 47 ), and step S120 is to initialize the interrupt (Interrupt) 48 .

After seeing the first boot icon 56, the user can decide whether to change the first boot indicator 58 according to the requirement. Then in step S130 it is judged whether there is a designation input via the input device 47 , if so, in step S140 it is judged whether the input command is a predetermined value corresponding to each boot device 46 . For example, when the input device 47 is a keyboard, and the representative will change the first boot pointer 58 to the default value (ie hot key) of the CD-ROM drive as F2, the processor 30 judges whether the user presses F2 to turn the first boot pointer 58 Point to the CD-ROM drive.

When the command input by the user is the same as the predetermined value, it means that the user intends to change the first boot device represented by the first boot indicator 58 through the hot key. Therefore, in step S150, the first boot pointer 58 is changed to point to the boot device 46 corresponding to the command. Next, proceed to step S160 , modify the first boot icon 56 according to the changed first boot indicator 58 , and load the changed first boot icon 56 into the random access memory 40 . Then in step S170 , the first boot icon 56 reloaded and stored in the random access memory 40 is displayed on the display device 44 . In this way, the user can know whether the change of the first boot indicator 48 is successful or not through the newly displayed first boot icon 56 .

Please refer to FIG. 4 and FIG. 6 at the same time. FIG. 6 is a schematic view showing a modification according to another embodiment of the present invention. For example, when the original first boot pointer 58 points to a hard disk, as shown in FIG. 4 , the display device 44 displays the first boot icon 56 corresponding to the hard disk. And when the user changes the first boot pointer 58 to an optical drive by inputting a hot key, as shown in FIG. 6 , the display result will also be changed to the first boot icon 56 representing the optical drive.

After the modification of the first boot indicator 58 is completed, the processor 30 executes the aforementioned step S170 and step S180 to search for and execute the startup program in the modified first boot device.

And when the user does not input an instruction, or the input instruction is not for changing the default value of the first power-on pointer 58 , the processor 30 executes the aforementioned step S180 and step S190 . The processor 30 searches each boot device 46 for a startup program in sequence according to the boot device sequence 54 , and loads the startup program to start the computer 20 completely.

According to the booting method of the present invention, the first booting icon stored in the BIOS is displayed according to the booting device sequence. Even if the user does not enter the setting menu, he can know the content of the first boot indicator at that time through the displayed first boot icon. In addition, the first boot icon can be displayed after the video graphic array is initialized and before the startup program starts to load, and a hot key is provided to change the first boot indicator. Therefore, when the user needs to change the first boot icon, he can input the hot keys corresponding to each boot device to change it within the time when the first boot icon is displayed. Because the first boot index is changed before the boot program is loaded, it is possible to directly go to the pointed new first boot device to find the boot program and start the computer without restarting the computer after changing the settings.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
