Abstract

<P>PROBLEM TO BE SOLVED: To quickly start a quick-start operating system in a device that uses a normal-start operating system or the quick-start operating system. <P>SOLUTION: A determination means 30 determines whether a quick-start command has been output or not. When the quick-start command is output, quick-start processing is performed by a quick-start means 32. When no quick-start command is output, normal-start processing is performed by a normal-start means 36. The normal-start means 36 successively reads data from devices 40, 42, ..., 44 in accordance with predetermined priority 38. When a boot loader is stored in a read device, an operating system recorded in the device is started according to the boot loader. The quick-start means 32 reads a boot loader of a predetermined quick-start device 34, and starts an operating system recorded in the quick-start device 34 according to the boot loader. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to an operating system startup technique.

  FIG. 1 shows a block diagram of a conventional personal computer. The CPU 4 is connected to a companion chip 2 (for example, Intel G45). The companion chip 2 is placed between an input / output device, a memory, and the like and the CPU 4 and controls the exchange of signals between them. Connected to the companion chip 2 are a mouse / keyboard 6, a C-MOS memory 8 backed up by a battery, a flash memory 9, a CD-ROM drive 10, a hard disk 12, a solid state drive (SSD) 14, a RAM 16, and the like. ing.

  A switch 22 is connected to the power supply terminal POWER of the companion chip 2. When the switch 22 is off, the power source 20 is supplied to the terminal POWER through the resistor 18. That is, when the switch 22 is off, “H” is supplied to the terminal POWER. When the switch 22 is pressed, “L” is supplied to the terminal POWER.

  The companion chip 2 supplies power to input / output devices such as the CPU 4 and the hard disk 12, the RAM 16, and the like when the terminal POWER becomes “L”. Thereby, the CPU 4 executes a BIOS (Basic Input Output System) program recorded in the flash memory 9.

  The BIOS program performs processing such as setting the register value to an initial value in order to initialize the RAM 16 and the input / output device. Then, according to the priority order recorded in advance in the C-MOS memory 8, it is checked whether a boot loader is recorded in each device. When a device in which the boot loader is recorded is found, the operating system is started according to the boot loader. As described above, the operating system is activated.

  There are computers that can record two or more operating systems and select and start them. For example, a normal startup operating system that starts normally is recorded on the hard disk 12, and a fast startup operating system that starts at high speed is recorded on the SSD 14. The SSD 14 is accessed faster than the hard disk 12, and in this example, the function of the fast startup operating system itself is limited, so that the startup time is shorter than that of a normal operating system.

  Therefore, when the user thinks that the function of the fast startup operating system is sufficient, the user can realize quick startup by selecting the fast startup operating system at the time of startup.

JP 2003-150379 A

  However, the apparatus capable of switching between the normal startup operating system and the fast startup operating system as described above has the following problems.

  The priority order of devices in the BIOS is predetermined. Therefore, the boot loader for the fast start operating system is read according to this priority order even at the high speed start. For this reason, there is a problem that it takes time to reach the device in which the fast startup operating system is recorded, and it takes time to start up the fast startup operating system. In particular, in a device such as the CD-ROM drive 10 that requires tracking for reading with a laser beam in order to read data, there is a problem that it particularly takes time.

  In this regard, Patent Document 1 discloses that a part of the diagnosis step is skipped in order to quickly start up the operating system. However, even the technique disclosed in Patent Document 1 cannot solve the above-described problem.

  The present invention solves the above-described problems and provides a technology capable of quickly starting a fast-start operating system in an apparatus capable of switching between a normal start operating system and a fast start operating system. The purpose is to do.

(1) An operating system activation device according to the present invention is an operating system activation device capable of switching between normal activation and high-speed activation, and has a determination means for determining the presence or absence of a high-speed activation command and a high-speed activation command. If a fast startup boot loader is read out from a predetermined fast startup device and a fast startup operating system is started and there is no fast startup command, the boot loader is installed in the device according to a predetermined priority. It is sequentially checked whether or not it is recorded, and when a device in which the boot loader is recorded is found, the boot loader is read out, and normal booting means for booting up the normal boot operating system is provided.

  Therefore, at the time of high-speed start-up, it is possible to immediately read out and start up the high-speed start-up operating system recorded in a predetermined device, thereby realizing quick start-up.

(2) The operating system booting apparatus according to the present invention is characterized by comprising fast initialization means for initializing only devices required for fast startup before the fast startup step when a fast startup command is issued. .

  Therefore, a fast startup operating system can be started up more quickly.

  In the present invention, “normal activation” refers to an activation method scheduled to sequentially access devices at least according to priority.

  “Fast start-up” refers to a start-up method that is scheduled to start from a predetermined device.

  The “normal startup operating system” refers to an operating system started by normal startup.

  “High-speed startup operating system” refers to an operating system that is started by high-speed startup.

  In the embodiment, “determination means” corresponds to step S13.

  In the embodiment, “high-speed activation means” corresponds to step S21.

  “There is a high-speed start command” is a concept that includes not only a case where there is a high-speed start command, but also a case where there is a command indicating that it is not a normal start-up.

  In the embodiment, the “fast start command” corresponds to the case where the output terminal G of the I / O port 50 becomes “L”.

  The “normal start command” corresponds to a case where only the output terminal POWER of the I / O port 50 becomes “L” in the embodiment.

  “No fast start command” is a concept that includes not only a fast start command but also a normal start command.

  In the embodiment, “normal activation means” corresponds to steps S15, S16, S17, and S18.

  In the embodiment, “high-speed initialization unit” corresponds to step S20.

  The “program” is a concept that includes not only a program that can be directly executed by the CPU, but also a source format program, a compressed program, an encrypted program, and the like.

1. Overall Configuration FIG. 2 is a functional block diagram of an operating system booting apparatus according to an embodiment of the present invention.

  The judging means 30 judges whether or not there has been a fast start command. If there is a high speed start command, the high speed start means 32 performs high speed start processing. If there is no high-speed start command, normal start processing is performed by the normal start means 36.

  The normal activation means 36 sequentially reads out the devices 40, 42... 44 in accordance with a predetermined priority order 38. If it can be started from the read device (if a boot loader is recorded), the operating system recorded in the device is started according to the boot loader.

  The fast start means 32 reads a predetermined boot loader of the fast start device 34. In accordance with this boot loader, the operating system recorded in the fast startup device 34 is started.

2. Hardware Configuration FIG. 3 shows a hardware configuration of an operating system booting apparatus according to an embodiment of the present invention.

  A companion chip 2 is connected to the CPU 4. The companion chip 2 includes a mouse / keyboard 6, a C-MOS memory 8 backed up by a battery, a flash memory 9, a CD-ROM drive 10, a hard disk 12, a solid state drive (SSD) 14 using a flash memory and the like. RAM 16 and the like are connected.

  A power switch 26 and a fast start switch 28 are connected to the input terminals A and B of the logic circuit 24. The logic circuit 24 receives inputs from the terminals A and B and changes its outputs P and G. The terminals P and G of the logic circuit 24 are connected to the terminals POWER and GPIO of the companion chip 2.

  FIG. 4 shows details of the logic circuit 24. The logic circuit 24 includes a CPU 52, a memory 54, and an I / O port 50. One end of the power switch 26 is connected to the power source 20 via the resistor R1, and the other end is grounded. One end of the fast start switch 28 is connected to the power source 20 via the resistor R2, and the other end is grounded. One end of the power switch 26 is connected to the input terminal A of the I / O port 50, and one end of the fast start switch 28 is connected to the input terminal B of the I / O port 50.

  Therefore, when the power switch 26 is off, “H” is applied to the input terminal A of the I / O port 50. When the power switch 26 is on (pressed), the I / O port 50 “L” is given to the input terminal A. Similarly, when the fast start switch 28 is off, “H” is given to the input terminal B of the I / O port 50. When the fast start switch 28 is on. When the button is pressed, “L” is given to the input terminal B of the I / O port 50.

  The CPU 52 changes the states of the output terminals P and G according to the states of the input terminals A and B of the I / O port 50. The output terminals P and G of the I / O port 50 are connected to the terminals POWER and GPIO of the companion chip 2. The BIOS program recorded in the flash memory 9 performs normal activation or high-speed activation based on the states of the terminals POWER and GPIO of the companion chip 2.

  In this embodiment, when the fast start switch 28 is pressed and the terminal GPIO of the companion chip 2 becomes “L”, the fast start is performed. When only the power switch 26 is pressed and the terminal GPIO of the companion chip 2 remains “H”, normal activation is performed.

  FIG. 5 shows the relationship between the states of the input terminals A and B of the I / O port 50 and the states of the output terminals P and G. When the input terminal A is “L” and the input terminal B is “H” (that is, when only the power switch 26 is pressed), the CPU 52 sets the terminal POWER of the companion chip 2 to “L” and the terminal GPIO. Set to “H”. Therefore, normal activation is performed.

  When the input terminal A is “H” and the input terminal B is “L” (that is, when only the fast start switch 28 is pressed), the CPU 52 sets the terminal POWER of the companion chip 2 to “L”. Set GPIO to “L”. Therefore, high-speed activation is performed.

  When both the input terminal A and the input terminal B are “L” (that is, when both the power switch 26 and the fast start switch 28 are pressed), the CPU 52 sets the terminal POWER of the companion chip 2 to “L”. The terminal GPIO is set to “L”. Therefore, high-speed activation is performed.

  The processing as described above is executed by the CPU 52 in accordance with the control program recorded in the memory 54. FIG. 6 shows a flowchart of the control program. The output terminals P and G of the I / O port 50 are normally “H”.

  In step S <b> 1, the CPU 52 determines whether the terminal B of the I / O port 50 is “L”. If “L”, the CPU 52 sets the output terminals P and G of the I / O port 50 to “L”. Then, after 0.1 seconds, the output terminal P is returned to “H”.

  On the other hand, if the terminal A of the I / O port 50 is “L”, the CPU 52 sets the output terminal P of the I / O port 50 to “L”. Then, after 0.1 seconds, the output terminal P is returned to “H”.

As described above, the processing of the CPU 52 can realize the relationship between the terminals P and G as shown in FIG.

3. BIOS Processing Next, FIG. 7 shows a flowchart of the BIOS program recorded in the flash memory 9. The CPU 4 determines whether or not the terminal POWER of the companion chip 2 is “L” (step S10). If the terminal POWER is “L” (that is, if the power switch 26 is pressed), the process proceeds to step S11. In this embodiment, if the terminal POWER of the companion chip 2 continues to be “L” for a predetermined time or longer, it is determined that the terminal POWER has become “L” even if the terminal POWER returns to “H” thereafter. Proceed to the process.

3.1 Normal Activation In step S11, the CPU 4 performs minimum necessary initialization for causing the terminal GPIO of the companion chip 2 to function as an input terminal. Here, the terminal GPIO is a terminal that can be either an input terminal or an output terminal. In initialization, it is necessary to set whether to use as an input terminal or an output terminal.

  When the initialization is completed, the CPU 52 acquires the state of the terminal GPIO (step S12). If the acquired state of the terminal GPIO is not “L”, the CPU 52 performs normal startup processing. First, the CPU 4 initializes all devices such as the mouse / keyboard 6, the C-MOS memory 8, the flash memory 9, the CD-ROM drive 10, the hard disk 12, the SSD 14, and the RAM 16.

  Next, the CPU 4 reads the priority order recorded in the C-MOS memory 8, and sets the device with the highest priority as the target device (step S15). For example, the CD-ROM drive 10 is the target device.

  The CPU 4 determines whether or not the CD-ROM drive 10 that is the target device exists. If it exists, it is determined whether or not a CD-ROM is inserted in the CD-ROM drive 10. If the CD-ROM is inserted, the CD-ROM drive 10 is operated to adjust the tracking, and then it is determined whether or not the recording format is “el trito” (step S16).

  If the recording format is “el trito”, the boot loader is read and executed from a predetermined location of the stored CD-ROM, and the normal startup operating system is started according to the boot loader (step S18).

  In step S16, if the CD-ROM drive 10 does not exist, or if the CD-ROM is not inserted, or the CD-ROM is inserted and the recording format is not "el trito", the CPU 4 Uses the next priority device as the target device (step S17). For example, the hard disk 12 is the target device. First, it is determined whether or not a hard disk exists (step S16).

  If it exists, the CPU 4 reads the boot loader from a predetermined location on the hard disk 12, and further starts the normal start operating system according to the boot loader (step S18).

3.2 Fast Startup If the terminal GPIO is “L” in step S13 (that is, if the fast startup switch 28 is pressed), the CPU 4 initializes only the devices necessary for the fast startup (step S20). ). For example, initialization is not performed for functions that are not supported by the fast-start operating system (for example, RS232C terminal). Therefore, faster startup can be performed.

  Next, the CPU 4 accesses the fast startup device according to the fast startup device name recorded in the C-MOS memory 8 in advance. For example, when the SSD 14 is set as the fast startup device, the boot loader recorded in the SSD 14 is read, and the fast startup operating system is started according to the boot loader (step S21).

As described above, the operating system for high-speed startup can be started up at high speed.

4). Other
(1) In each of the above embodiments, the normal boot device and the fast boot device are separated. However, the normal boot device and the fast boot device may be the same device. For example, the normal startup operating system and the fast startup operating system may be recorded on the hard disk 12.

  FIG. 8 shows a state where the normal boot operating system 100 and the fast boot operating system 200 are recorded on the hard disk 12. A primary boot loader 102 for the normal boot operating system 100 is recorded at the head of the hard disk. The secondary boot loader 104 is recorded at the head of the partition α, and subsequently, the normal boot operating system 100 is recorded.

  At the head of the partition β, a primary boot loader 202 for the high-speed startup operating system 200, a secondary boot loader 204, and a high-speed startup operating system 200 are recorded.

  In this embodiment, WINDOWS (trademark) is used as the normal boot operating system 100 and LINUX (trademark) is used as the fast boot operating system 200.

  At the normal startup in step S18 of FIG. 7, the CPU 4 reads the partition type described in the primary boot loader 102. The partition type describes the data format of each partition. For example, the partition α is described as “NTFS”, and the partition β is described as “LINUX”.

  When the normal activation is WINDOWS (trademark), it is predetermined to read the partition of “NTFS”. For example, by recording a flag or the like in the C-MOS memory 8, it is determined in advance from which data format the partition is read. Therefore, the CPU 4 reads the primary boot loader 102 and reads and executes the secondary boot loader 104 of the partition α by the primary boot loader 102. The secondary boot loader 104 activates the normal activation operating system 100 (WINDOWS (trademark)).

  At the time of high-speed startup in step S21 in FIG. 7, the CPU 4 performs the following processing. When the fast startup is LINUX (trademark), it is predetermined to read the partition of “NTFS”. Therefore, the CPU 4 reads the primary boot loader 202 of the partition β and reads and executes the secondary boot loader 204 by the primary boot loader 202. The secondary boot loader 204 starts up a high-speed startup operating system (LINUX (trademark)) 200.

  As described above, the normal boot operating system 100 and the fast boot operating system 200 can be recorded on the same device to implement the present invention.

(2) In each of the above embodiments, both the normal boot operating system and the fast boot operating system are recorded. However, one operating system may be used for both the normal boot operating system and the fast boot operating system.

(3) In each of the above embodiments, the mechanical switch is used as the power switch 26 and the fast start switch 28, but a sensor such as a touch sensor or a photoelectric sensor may be used.

(4) In the above embodiments, a personal computer has been described as an example. However, the present invention can also be applied to devices such as PDAs and game machines with a built-in CPU.
