Hereinafter, embodiments will be described with reference to the drawings.
[1] One Embodiment [1-1] Configuration Example of Information Processing Device FIG. 1 is a diagram illustrating a hardware configuration example of an information processing device 1 as an embodiment, and FIG. It is a block diagram which shows the detailed structural example of these. In FIG. 2, illustration of some components is omitted for convenience of explanation.

The information processing apparatus 1 mounts UEFI (Unified Extensible Firmware Interface) as system firmware, and starts and executes a basic system corresponding to UEFI.
An example of the basic system is an OS (Operating System). Hereinafter, a case where the basic system is an OS will be described.

As illustrated in FIG. 1, an information processing apparatus 1 includes a CPU (Central Processing Unit) 2, a memory 3, an NVRAM (Non-Volatile Random Access Memory) 4, an HDD (Hard Disk Drive) 5, an input device 6, and a display. A device 7 is provided.
The memory 3 is a storage area for temporarily storing various data and programs. When the CPU 2 executes the programs, the data and programs are temporarily stored and expanded. As the memory 3, for example, a volatile memory such as a RAM can be cited.

The HDD (storage unit) 5 is a storage device that stores various data, programs, and the like, and in this embodiment, stores an OS (basic system) 5C corresponding to the UEFI shown in FIG. Other storage devices such as a semiconductor drive device such as an SSD (Solid State Drive) may be used instead of the magnetic disk device such as the HDD 5.
Here, the HDD 5 has a partition set by GPT (GUID Partition Table), and holds a partition GUID (Globally-Unique Identifier) 5A and a partition type GUID 5B in the partition (area) in which the OS 5C to be used is stored. is doing.

The partition GUID (first area information) 5A is a GUID related to the partition storing the OS 5C as described above, and is unique for each partition of the HDD 5.
FIG. 3 is a diagram illustrating an example of the partition GUID 5A held by the HDD 5 according to the embodiment.
As shown in FIG. 3, the HDD 5 has, for example, a GUID that is a 16-byte value (indicated as {GUID 1} in FIG. 3 for convenience) and the type of OS 5C to be stored (in this example, “Windows (registered trademark) x64 ”) Is stored as the partition GUID 5A.

The partition type GUID (first OS information, first basic system information) 5B is a GUID related to the OS 5C to be stored, and is a GUID uniquely determined by the OS 5C and the partition format used by the OS 5C as described above. The partition type GUID5B is a value of 16 bytes, for example. As an example, when the OS 5C to be stored is “Windows (registered trademark) x64” and the partition format is “LDM”, the partition type GUID 5B is “5808C8AA-7E8F-42E0-85D2-E1E90434CFB3”.

Hereinafter, the HDD 5 according to the present embodiment will be described assuming that the OS 5C to be stored is “Windows (registered trademark) x64” and the partition format is “LDM”.
Hereinafter, the partition GUID 5A is also simply referred to as GUID 5A, and the partition type GUID 5B is also simply referred to as GUID 5B.
The NVRAM (holding unit) 4 stores a UEFI F / W (firmware) 41 that is system firmware of the information processing apparatus 1. The UEFI F / W 41 is read by the CPU 2 after the information processing apparatus 1 is turned on, and controls until the execution of the OS 5C is started. Instead of NVRAM 4, another readable / writable nonvolatile memory may be used.

Further, the NVRAM 4 includes a variable area that is a specific area in the storage area of the UEFI F / W 41, and the partition GUID 4A corresponding to the partition GUID 5A of the HDD 5 is stored in the partition GUID list 42 when the OS 5C is installed. Note that the partition GUID 4A is written to the variable area by executing a runtime function of the UEFI F / W 41 by the OS 5C.

In the information processing apparatus 1 according to the present embodiment, the runtime function is also executed in the HDD 5 registration process by the GUID registration unit 22 described later, and the partition GUID 4A is written to the partition GUID list 42 in the Variable area. It is.
The partition GUID list (registration information) 42 has at least one partition GUID 4A.

The partition GUID (second area information) 4A is a GUID written by the runtime function as described above, and corresponds to the partition GUID 5A stored in the HDD 5.
Hereinafter, the partition GUID list 42 is also simply referred to as a GUID list 42, and the partition GUID 4A is also simply referred to as GUID 4A.

FIG. 4 is a diagram showing an example of the partition GUID list 42 held by the NVRAM 4 according to the embodiment.
As illustrated in FIG. 4, the NVRAM 4 holds, as a partition GUID 4A, information including at least the GUID and the type of the OS 5C to be stored in the variable area. As shown in FIG. 4, the NVRAM 4 may hold a GUID 4 </ b> A that is a set of a plurality of GUIDs and the type of OS 5 </ b> C to be stored in the GUID list 42.

For example, as shown in FIG. 4, the GUID list 42 in the variable area includes the same GUID as GUID 5A held by the HDD 5 (indicated as {GUID 1} in FIG. 4 for convenience) and the type of OS 5C to be stored (in this example). Includes at least “Windows (registered trademark) x64”) as GUID 4A. Further, for example, in this GUID list 42, another GUID (indicated as {GUID 2} in FIG. 4 for convenience) and the type of OS stored in the partition relating to the other GUID (in this example, “Linux ( The information including at least the registered trademark))) is further held as the partition GUID 4A.

Further, the NVRAM 4 holds a support partition type GUID list 43 related to the OS 5C that is permitted to be activated by the CPU 2.
In the supported partition type GUID list (startup permission information) 43, at least one partition type GUID4B and a startability flag 4C are registered.
The partition type GUID (second OS information, second basic system information) 4B is a GUID related to at least one OS, and is a GUID uniquely determined by the OS and the partition format used by the OS, similarly to the partition type GUID5B. .

The boot availability flag (boot availability information) 4C is information indicating whether the OS can be activated by the CPU 2, and is associated with the partition type GUID4B.
Hereinafter, the support partition type GUID list 43 is also simply referred to as a partition type GUID list 43 or a GUID list 43, and the partition type GUID4B is also simply referred to as GUID4B.

FIG. 5 is a diagram showing an example of the partition type GUID list 43 held by the NVRAM 4 according to the embodiment.
As shown in FIG. 5, the partition type GUID list 43 holds a plurality of partition types GUID4B and an activation enable / disable flag 4C associated with these GUID4B.

For example, as illustrated in FIG. 5, when the OS is “Windows (registered trademark) x64” and the partition format is “LDM”, the partition type GUID4B indicates that the system can be started as a bootable flag 4C. 1 "is set. On the other hand, in the partition type GUID4B when the OS is “HP-UX (registered trademark)” and the partition format is “Service”, “0” indicating that the activation is impossible is set as the activation permission flag 4C. .

In FIG. 5, for convenience of explanation, the OS type and the partition format are shown after the partition type GUID4B. However, in reality, only a 16-byte value is set in the partition type GUID4B.
Further, for example, the system administrator can update the GUID 4B by adding, changing, or deleting the GUID 4B in the partition type GUID list 43 by executing an application that rewrites the NVRAM 4 or the like. Thereby, addition of a new OS that is not included in the GUID list 43, deletion of an unnecessary OS, and the like can be easily performed without updating the UEFI F / W 41 itself, and convenience is improved.

Note that the activation permission flag 4C in the partition type GUID list 43 can be changed by setting the activation OS by the parameter setting unit 23 described later.
The input device 6 is used to input data, instruction contents, and the like to the CPU 2 by various inputs and operations performed by a user or administrator of the information processing device 1 (hereinafter simply referred to as a user or the like). For example, it is configured with a mouse and a keyboard.

The display device 7 displays various information from the CPU 2 and is configured to include, for example, a monitor.
The CPU (processing unit) 2 is a processing device (processor) that performs various controls and operations, and temporarily stores and expands programs stored in the HDD 5, NVRAM 4, ROM (not shown), etc. in the memory 3 and executes them. By doing so, various functions are realized.

The CPU 2 also includes a cache memory (hereinafter referred to as CM) 20 that holds data and the like transferred between the CPU 2 and the memory 3 or the NVRAM 4.
Further, the CPU 2 performs a setting process of the information processing apparatus 1 and a startup process of the OS 5C by executing the UEFI F / W 41. Here, the setting process of the information processing apparatus 1 includes a startup process (POST process) of the information processing apparatus 1 including a startup preparation of the OS 5C, a setting process of a startup OS and HDD registration setting process described later, and an HDD registration process. Etc.

Hereinafter, the information processing apparatus 1 and the OS activation process performed by the execution of the UEFI F / W 41 by the CPU 2 will be described with reference to FIG.
FIG. 6 is a flowchart for explaining an example of the boot process (POST process) of the information processing apparatus 1 and the boot process of the OS according to the embodiment.
As shown in FIG. 6, for example, when the power button of the information processing apparatus 1 is pressed and the power is turned on (step S1), the CPU 2 is initialized in the SEC (Security) phase, and the CM 20 becomes usable. (Step S2).

Next, in the PEI (Pre EFI Initialization) phase, the CPU 2 reads out the execution modules constituting the UEFI F / W 41 from the NVRAM 4 to the CM 20 and mainly executes initialization of the chipset and the memory 3 (step S3).
Here, the UEFI F / W 41 is a collection of execution modules called FV (Firmware Volume). After the power is turned on, a module called BFV (Boot Firmware Volume) is first executed in the UEFI F / W 41, and the PEI in step S3 described above is executed in this BFV.

Next, in the DXE (Driver Execution Environment) phase, the CPU 2 reads the execution module from the NVRAM 4 into the memory 3, and mainly executes the setting of the built-in device and various functions (step S4).
When the initialization process of the system platform in steps S2 to S4 is completed, a boot manager incorporated in the UEFI F / W 41 is activated, and a UEFI-compatible OS to be activated is selected (step S5). Then, the selected UEFI-compatible OS is activated by the Final OS Boot Loader (Steps S6 and S7), and the POST process is terminated.

Here, the CPU 2 includes an OS activation determination unit 21, a GUID registration unit 22, and a parameter setting unit 23.
The OS activation determination unit (basic system activation determination unit, determination unit) 21 determines whether or not the partition GUID 4A corresponding to the partition GUID 5A is held in the NVRAM 4 in the setting process of the information processing apparatus 1.

Specifically, the OS activation determination unit 21 acquires the partition GUID 5A (see FIG. 3) set in the HDD 5 of the OS 5C to be activated in the execution of the boot manager in step S5 illustrated in FIG. Then, the OS activation determination unit 21 determines whether or not the acquired GUID 5A matches the partition GUID 4A (see FIG. 4) in the partition GUID list 42 of the NVRAM 4.

Further, when the OS activation determination unit 21 determines that the GUID 4A corresponding to the GUID 5A is held in the NVRAM 4, the OS activation determination unit 21 stores it in the HDD 5 based on the partition type GUID 5B and the partition type GUID list 43 (see FIG. 5). It is determined whether or not to perform the startup process of the OS 5C.
Specifically, the OS activation determination unit 21 determines whether or not the GUID 4B corresponding to the GUID 5B is registered in the GUID list 43. If it is determined that the GUID 4B is registered, the OS activation determination unit 21 associates the GUID 4B with the GUID 4B. It is determined that the activation process of the OS 5C is performed according to the activation permission flag 4C. More specifically, the OS activation determination unit 21 determines to perform the activation process of the OS 5C when it is determined that the activation availability flag 4C associated with the GUID 4B indicates that activation is possible.

Then, the CPU 2 performs OS 5 C activation processing according to the determination result by the OS activation determination unit 21. Specifically, when the OS activation determination unit 21 determines that the OS 5C activation process is to be performed, the CPU 2 executes the processes of steps S6 and S7 shown in FIG. 6 to perform the OS 5C activation process.
FIG. 7 is a diagram illustrating an example of HDD registration processing by the GUID registration unit 22 according to an embodiment.

When the OS startup determination unit 21 determines that the partition GUID 4A corresponding to the partition GUID 5A is not held in the NVRAM 4, the GUID registration unit (registration unit) 22 stores the GUID 5A in the NVRAM 4 as the GUID 4A corresponding to the GUID 5A. sign up.
Specifically, when it is determined that the GUID 4A corresponding to the GUID 5A is not held in the NVRAM 4, the GUID registration unit 22 sets the GUID 5A as the GUID 4A based on a predetermined registration condition and the variable area (GUID list 42) of the NVRAM 4. In).

Here, the GUID registration unit 22 performs registration in the variable area of GUID4A using a runtime function of flash ROM (NVRAM4) access, which is a function of UEFI F / W41. That is, the GUID registration unit 22 according to the present embodiment executes the runtime function used when installing the OS 5C in the determination process performed by the OS activation determination unit 21.

When the partition GUID 5A is registered in the NVRAM 4 by the GUID registration unit 22, the OS activation determination unit 21 performs the OS 5C activation process based on the GUID 5A stored in the HDD 5 and the GUID 4A registered by the GUID registration unit 22. Determine whether or not to do so.
That is, even when the OS activation determination unit 21 determines that the GUID 4A corresponding to the GUID 5A is not held in the variable area of the NVRAM 4, when the GUID registration unit 22 registers the GUID 4A in the variable area, Then, it is possible to determine whether the OS 5C can be activated based on the GUID list 43.

Here, whether the GUID registration unit 22 satisfies a predetermined registration condition is determined by setting automatic registration and manual registration for the GUID 5A corresponding to the GUID 4A not held in the NVRAM 4, that is, the unregistered partition GUID 5A ( "Valid" or "invalid").
Specifically, the GUID registration unit 22 indicates that the automatic registration is “valid” and the automatic registration is “invalid” but the manual registration is “valid” and the registration is permitted by the user or the like. In any case, it is determined that a predetermined registration condition is satisfied.

For example, when the unregistered partition GUID 5A is recognized by the OS activation determination unit 21 and the automatic registration is “valid”, the GUID registration unit 22 determines that a predetermined registration condition is satisfied, Unregistered GUID 5A is registered in NVRAM 4 as GUID 4A.
Further, when the unregistered partition GUID 5A is recognized, the GUID registration unit 22 determines that the automatic registration is “invalid” but the manual registration is “valid” with respect to the display device 7 as shown in FIG. A selection screen 22A as shown in FIG. 6 is displayed, and the user or the like is allowed to select whether or not to register the HDD 5 (GUID 5A).

When the user or the like gives an instruction to permit registration (input “y” in the example shown in FIG. 7) via the input device 6, the GUID registration unit 22 uses a predetermined registration condition. Therefore, the unregistered GUID 5A is registered in the NVRAM 4 as the GUID 4A. On the other hand, when an instruction not to register (input of “n” in the example shown in FIG. 7) is issued, the GUID registration unit 22 determines that the predetermined registration condition is not satisfied, and registers the GUID 5A. Instead, the OS activation determination unit 21 determines not to activate the OS.

If both automatic registration and manual registration are “invalid”, the GUID registration unit 22 determines that the predetermined registration condition is not satisfied, does not register the GUID 5A, and the OS activation determination unit 21 It is determined that the OS activation process is not performed.
The setting information for automatic registration and manual registration is held in a predetermined area of the NVRAM 4 as, for example, a flag “1” indicating “valid” and a flag “0” indicating “invalid”. These flags are read by the GUID registration unit 22 and used to determine whether or not a predetermined registration condition is satisfied.

The parameter setting unit (setting unit) 23 can set the activation enable / disable flag 4C for each partition type GUID 4B in the GUID list 43.
Further, the parameter setting unit 23 can set automatic registration and manual registration used by the GUID registration unit 22 for a determination related to a predetermined registration condition.
The parameter setting process by the parameter setting unit 23 such as the activation enable / disable flag 4C and automatic registration / manual registration setting information is performed by, for example, the input device 6 by the user after the completion of the DXE phase processing in step S4 shown in FIG. This is executed when the UEFI F / W 41 setup (parameter setting) is requested via.

FIG. 8 is a diagram for explaining an example of a boot OS and HDD registration setting process by the parameter setting unit 23 according to the embodiment.
In the parameter setting process, the parameter setting unit 23 causes the display device 7 to display a setup screen 23A reflecting the current parameter setting value, for example, as shown in FIG. Specifically, the parameter setting unit 23 “bootable” according to the type of the OS related to the GUID 4B currently held in the partition type GUID list 43 and the value of the boot enable / disable flag 4C corresponding to the OS. Display the status of “Cannot start”. Further, the parameter setting unit 23 reads and displays “valid” or “invalid” setting information of automatic registration and manual registration related to the GUID registration unit 22 held in the NVRAM 4.

For example, as shown in FIG. 8, the “UEFI-compatible OS boot enable / disable setting” display field has an OS in which “1”, that is, “boot enable” is set in the value of the boot enable / disable flag 4C. (Registered trademark) x64 "and" Red Hat Linux (registered trademark) "are displayed (see FIG. 5). In the display column of “UEFI-compatible OS boot enable / disable setting”, “FreeBSD (registered trademark)”, “ "MacOS (registered trademark) X", "Solaris (registered trademark)", and "HP-UX (registered trademark)" are displayed (see FIG. 5).

As an example, in the case where both the automatic registration and manual registration flags in NVRAM 4 are set to “0”, as shown in FIG. 8, the display column of “setting of HDD GUID registration method” is displayed. “Invalid”, that is, “Not used” is displayed for automatic registration, and “Invalid”, that is, “Not permitted” is displayed for manual registration.
The user or the like can change and save the setting for each parameter described above through the operation of the input device 6 on the setup screen 23A of the UEFI F / W 41 displayed on the display device 7.

For example, when an HDD in which “FreeBSD (registered trademark)” is installed as the OS type is changed to “bootable”, the user or the like can set “boot” set in “FreeBSD (registered trademark)” on the setup screen 23A. Change “Disable” to “Startable” and save. As a result, even when an HDD in which “FreeBSD (registered trademark)” is installed is connected, if the GUID 5A in this HDD is registered in the NVRAM 4 (or if it is registered by the HDD registration process), the OS is started. become able to. As described above, by the setting process by the parameter setting unit 23, only the HDD in which the OS permitted by the user or the like (for example, the system administrator) is installed can be activated.

When the setting information is changed and saved by the user or the like for the parameters displayed on the display device 7 as shown in FIG. 8, the parameter setting unit 23 displays the changed parameters in the GUID held in the NVRAM 4. It is reflected in the setting information of the list 43 or automatic registration and manual registration. That is, the parameter setting unit 23 sets (overwrites) the changed parameter in the GUID list 43 or the setting information for automatic registration and manual registration.

When the setting process in the setup utility shown in FIG. 8 is finished by the parameter setting unit 23 and the setting information of the GUID list 43 or automatic registration and manual registration is changed, the changed content is the next OS activation determination unit 21. This is applied when determining whether or not the OS 5C can be activated using the GUID list 43, or when the GUID registration unit 22 registers the HDD 5.
Note that the setup menu item shown in FIG. 8 by the parameter setting unit 23 is preferably set with a password for transition to the setting screen 23A so that only the system administrator of the information processing apparatus 1 can operate, for example. As a result, registration by a user without system authority becomes impossible, which improves security and facilitates management.

[1-2] Information Processing Device Setting Processing and OS Startup Processing Next, an example of the information processing device 1 setting processing and OS 5C startup processing in the information processing device 1 according to the embodiment configured as described above. explain.
FIG. 9 is a flowchart illustrating an example of the setting process of the information processing apparatus 1 and the startup process of the OS 5C according to an embodiment. In addition, the flowchart shown in FIG. 9 explains the detail of the process of step S4 to step S7 shown in FIG.

First, as shown in FIG. 9, the CPU 2 executes the DXE dispatcher (Dispatcher) of the UEFI F / W 41, and executes processing such as initialization for the device in the DXE phase (step S11; see step S4 in FIG. 6). ).
Next, the CPU 2 detects a BDS (Boot Device Selection) entry in the HDD 5 (step S12). If no BDS entry is detected in step S12, the HDD 5 is not set in the GPT and does not store an OS corresponding to UEFI. Therefore, the CPU 2 does not perform the processes in and after step S13, That is, the OS is started by the conventional BIOS method. The legacy boot can be performed by a known method, and detailed description thereof is omitted.

When a BDS entry is detected in step S12, the CPU 2 executes the boot manager (OS activation determination unit 21) (step S13; see step S5 in FIG. 6).
Next, the partition GUID 5A is referenced (acquired) from the partition of the HDD 5 in which the OS 5C is stored by the OS activation determination unit 21. Further, the OS activation determination unit 21 refers to the partition GUID list 42 from the variable area of the NVRAM 4, and determines whether or not there is a GUID 4A that matches (corresponds) to the GUID 5A in the GUID list 42 (step S14). .

When it is determined that there is no GUID 4A that matches the GUID 5A (No route of step S14), the OS activation determination unit 21 executes a registration process of the HDD 5 (GUID 5A) shown in FIG. 10 described later (step S15). .
Then, the OS activation determination unit 21 determines whether or not the HDD 5 is registered in step S15 (step S16). If it is determined that the HDD 5 is not registered (No route in step S16), the OS activation determination unit. 21 determines that the OS 5C stored in the HDD 5 cannot be recognized (step S24), and the process ends. Specifically, the CPU 2 displays a message such as “OS Not Found” on the display device 7, and the OS startup process ends.

On the other hand, if it is determined in step S16 that the HDD 5 has been registered (Yes route in step S16), or if it is determined in step S14 that there is a GUID 4A that matches GUID 5A (Yes route in step S14). Then, the process proceeds to the following step S17.
That is, in step S 17, the partition type GUID list 43 is read from the NVRAM 4 into the memory 3 by the OS activation determination unit 21.

Further, the OS startup determination unit 21 refers to (acquires) the partition type GUID5B from the partition of the HDD5 in which the OS5C is stored, and whether the acquired GUID5B matches the GUID4B indicated by the current pointer of the GUID list 43 (whether it corresponds) It is determined whether or not (step S18).
If they do not match (No route of step S18), the OS activation determination unit 21 advances the pointer of the GUID list 43 next (step S22), and GUID4B is at the position indicated by the changed pointer of the GUID list 43. Whether or not the GUID list 43 has been referred to the end (step S23).

If it is determined that there is GUID 4B at the position indicated by the pointer of the GUID list 43, that is, the GUID list 43 has not been referred to yet (Yes route in step S23), the process proceeds to step S18.
As described above, in steps S17, S18, S22, and S23, the OS activation determination unit 21 compares the GUID 5B recorded in the partition of the HDD 5 with the GUID list 43 in the NVRAM 4, and selects the GUID 4B that matches the GUID 5B. Search for.

On the other hand, when it is determined that there is no GUID 4B at the position indicated by the pointer in the GUID list 43, that is, the GUID list 43 has been referred to the end (No route in step S23), the process proceeds to step S24, and the process ends.
If it is determined in step S18 that the acquired GUID 5B matches the GUID 4B indicated by the pointer in the GUID list 43 (Yes route in step S18), the OS activation determination unit 21 determines whether the activation is associated with the matched GUID 4B. The value of the flag 4C is confirmed (step S19).

Then, the OS activation determination unit 21 determines whether or not the value of the activation availability flag 4C is “1”, that is, “activation is possible” (step S20).
When the value of the boot enable / disable flag 4C is “startable” (Yes route in step S20), the CPU 2 registers the information related to the GUID 5B in the boot manager OS boot area of the NVRAM 4 so that the OS 5C can be booted. The Then, the CPU 2 executes a startup process for the UEFI-compatible OS 5C related to the partition type GUID 5B stored in the HDD 5 (step S21; see steps S6 and S7 in FIG. 6), and the process ends.

On the other hand, if it is determined in step S20 that the value of the activation feasibility flag 4C is “0”, that is, “activation is impossible” (No route in step S20), the process proceeds to step S24, and the process is performed. finish.
With the above processing, the setting processing of the information processing device 1 and the startup processing of the OS 5C in the information processing device 1 are performed.

[1-3] HDD Registration Processing Next, an example of HDD 5 (GUID 5A) registration processing in the information processing apparatus 1 according to the embodiment configured as described above will be described.
FIG. 10 is a flowchart illustrating an example of registration processing of the HDD 5 in the information processing apparatus 1 according to an embodiment. Note that the flowchart shown in FIG. 10 explains details of the processing in step S15 shown in FIG.

First, when the registration process of the HDD 5 (GUID 5A) is executed in step S15 of FIG. 9 (step S31), the GUID registration unit 22 is activated.
Next, the GUID registration unit 22 refers to the automatic registration setting information stored in a specific area of the NVRAM 4 to determine whether or not the automatic registration is set to “1 (valid)”, that is, “use”. (Step S32).

When the automatic registration is set to “use” (Yes route in step S32), the runtime registration function of the UEFI F / W 41 flash ROM (NVRAM4) is used by the GUID registration unit 22 and GUID5A is stored in the NVRAM4. It is registered (added) in the GUID list 42 (step S35). Then, the registration process of the HDD 5 ends, and the process proceeds to step S16 shown in FIG.

On the other hand, when the automatic registration is set to “not use” in step S32 (No route in step S32), the GUID registration unit 22 refers to the setting information for manual registration stored in a specific area of the NVRAM 4. Then, it is determined whether or not the manual registration is set to “1 (valid)”, that is, “permitted” (step S33).
When the manual registration is set to “permitted” (Yes route in step S33), the GUID registration unit 22 displays the selection screen 22A (see FIG. 7) on the display device 7 and causes the user or the like to display the HDD 5 ( Whether to register GUID5A) is selected (step S34).

When an instruction to permit registration of the HDD 5 is input (Yes route in step S34), the process proceeds to step S35.
On the other hand, when manual registration is set to “non-permitted” in step S33 (No route of step S33), or when an instruction not permitting registration of the HDD 5 is input in step S34 (step S34). No route), the GUID registration unit 22 does not register the HDD 5, and the process ends. And it transfers to the process of step S16 shown in FIG.

With the above processing, the HDD 5 registration processing in the information processing apparatus 1 is performed.
As described above, according to the information processing apparatus 1 according to the present embodiment, the GUID registration unit 22 registers the GUID 5A as the GUID 4A in the NVRAM 4 even when the GUID 4A corresponding to the GUID 5A is not held in the NVRAM 4.
Therefore, even when the HDD 5 is replaced in the information processing apparatus 1 on which UEFI is mounted, it is possible to start the OS 5C stored in the replaced HDD 5 that could not be performed in the past. The convenience of the device 1 is improved.

In addition, even when the copied OS 5C is installed in the HDD 5 having a capacity larger than that of the copy source HDD 5, the OS 5C copied from the copy destination HDD 5 can be activated according to the implementation of the boot loader. Will improve.
Moreover, according to the information processing apparatus 1 according to the present embodiment, the GUID registration unit 22 registers the GUID 5A as the GUID 4A in the NVRAM 4 based on predetermined registration conditions.

Therefore, even if the user replaces the HDD 5 without the administrator's permission, if the predetermined registration conditions are not satisfied, the OS 5C stored in the replaced HDD 5 can be prevented from being activated, and system management can be performed. As a result, the load on the operator and the support center can be reduced and the security can be improved.
Furthermore, according to the information processing apparatus 1 according to the present embodiment, the NVRAM 4 holds the GUID list 43 related to the OS that is permitted to be activated by the CPU 2. When the OS activation determination unit 21 determines that the HDD 5 (GUID 5A) is registered in the NVRAM 4, the OS 5C stored in the HDD 5 is stored in the HDD 5 based on the GUID 5B stored in the HDD 5 and the GUID list 43. It is determined whether or not to perform the startup process.

Therefore, in the UEFI environment, it is possible to perform control so that only the HDD 5 in which the OS 5C permitted (approved) by the administrator is installed can be activated. For example, it is possible to control to start only the OS 5C corresponding to the information processing apparatus 1 or the OS 5C that has been evaluated by the administrator, and the support load and cost can be reduced.
Even when the HDD 5 set by GPT is replaced, if the OS 5C permitted (approved) by the administrator is installed in the replaced HDD 5, the OS 5C can be easily started from the replaced HDD 5. The security and convenience of the information processing apparatus 1 are improved.

In addition, according to the information processing apparatus 1 according to the present embodiment, the parameter setting unit 23 sets the activation permission flag 4C for each GUID 4B in the GUID list 43.
Therefore, in the UEFI environment, setting of the OS 5C permitted (approved) by the administrator can be easily performed using, for example, the setup utility of the UEFI F / W 41, and the support load and cost can be reduced.

Furthermore, according to the information processing apparatus 1 according to the present embodiment, the OS activation determination unit 21 registers the GUID 4B corresponding to the GUID 5B in the GUID list 43, and the activation enable / disable flag 4C associated with the GUID 4B is activated. When it is determined that it is possible, it is determined that the OS 5C activation process is performed. In other words, when the activation permission flag 4C indicates that the activation is impossible, the OS activation determination unit 21 suppresses the activation process of the OS 5C.

Therefore, even if the user replaces the HDD 5 without permission from the administrator and the predetermined registration conditions are satisfied, if the unsupported OS 5C is installed in the replaced HDD 5, It is possible to prevent the OS 5C from starting up. As a result, the load on the system administrator and the support center can be reduced, and security can be improved.
