Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic block diagram showing a hardware configuration of an information processing apparatus 100 according to an embodiment of the present invention.
The information processing apparatus 100 according to the present embodiment includes a nonvolatile memory 110, a CPU 120, a memory 130, a root port 140, and a plurality of expansion cards 150-1 to 150-N (hereinafter, expansion cards 150-1 to 150-N are collectively referred to). In this case, the expansion card 150 is provided.

The nonvolatile memory 110 stores a BIOS (Basic Input / Output System) (program) of the information processing apparatus 100, automatic startup information indicating an OS (Operating System) that performs automatic startup, and a boot path for each OS. That is, the nonvolatile memory 110 is an example of a boot path storage unit that stores a boot path. The boot path is information indicating the location of the expansion card 150 used for starting the OS. That is, the OS is stored in an external storage medium (storage or disk) connected to the expansion card 150.
The CPU 120 executes the BIOS stored in the nonvolatile memory 110, initializes the expansion card 150, and starts the OS.
The memory 130 stores information used for processing executed by the CPU 120.
The root port 140 mediates the connection between the plurality of expansion cards 150 and the CPU 120, and determines whether the expansion card 150 and the CPU 120 under its control are logically connected (Enable) or disconnected (Disable) for each expansion card 150. A link register for storing is provided.
The expansion card 150 is a card that expands the functions of the information processing apparatus 100, and includes an option ROM 151 that stores an initialization program used for its own POST (Power On Self Test) (initialization). For example, a PCI card is used as the expansion card 150.

Next, the BIOS according to the present embodiment will be described.
FIG. 2 is a schematic block diagram showing a software configuration of the CPU 120 when the BIOS is executed.
When the BIOS stored in the nonvolatile memory 110 is executed, the CPU 120 includes an I / O unit 121 (Input / Output), an automatic activation determination unit 122, a boot path analysis unit 123, a link register setting unit 124, and a POST execution unit 125.

The I / O unit 121 reads information from the nonvolatile memory 110. Further, the I / O unit 121 writes information into the nonvolatile memory 110. The I / O unit 121 is an example of a boot path acquisition unit that acquires a boot path of an OS that performs automatic startup from the nonvolatile memory 110.
The automatic startup determination unit 122 determines whether there is an OS to be automatically started based on the automatic startup information read from the nonvolatile memory 110 by the I / O unit 121.
The boot path analysis unit 123 analyzes the boot path read from the non-volatile memory 110 by the I / O unit 121, and specifies the expansion card 150 used for starting the OS.
The link register setting unit 124 rewrites the link register of the root port 140. The link register setting unit 124 includes a disconnection unit that logically disconnects the expansion card 150 other than the expansion card 150 indicated by the boot path, and an expansion card 150 that is logically disconnected after the expansion card 150 is initialized. It is an example of the connection part which connects logically.
The POST execution unit 125 executes POST on the expansion card 150 whose link register value of the root port 140 indicates “Enable”. That is, the POST execution unit 125 is an example of an initialization unit that initializes the expansion card 150 indicated by the boot path.

Next, a method for starting the information processing apparatus 100 according to the present embodiment will be described.
FIG. 3 is a flowchart illustrating a method for starting the information processing apparatus 100.
First, the CPU 120 of the information processing apparatus 100 reads the BIOS from the nonvolatile memory 110, allocates bus resources, and performs link connection with the expansion card 150, thereby starting up the BIOS (step S1). Note that the processing of this step is executed on the order of milliseconds, so the effect on the startup time due to the number of expansion cards 150 mounted is negligible.

  When the CPU 120 starts up the BIOS, the I / O unit 121 of the CPU 120 reads the automatic activation information from the nonvolatile memory 110 (step S2). Next, the automatic activation determination unit 122 determines whether the automatic activation information read by the I / O unit 121 indicates a valid value (step S3).

  When the automatic activation determination unit 122 determines that the automatic activation information indicates a valid value, that is, when the automatic activation information indicates information of an OS that performs automatic activation (step S3: YES), the I / O unit 121 The boot path associated with the OS indicated by the automatic startup information is read from the nonvolatile memory 110 (step S4).

  Next, the boot path analysis unit 123 analyzes the boot path read by the I / O unit 121, and specifies the expansion card 150 used for starting the OS (step S5). Specifically, the boot path acquired by the I / O unit 121 is described in the following format.

  AcpiEx (PNP0A08, PNP0A03, 0x0) / Pci (0x1,0x0) / Pci (0x0,0x0) / SAS (0x5000C5003AB04F4D, 0x0,0x1, NoTopology, 0,0,0,94,0PT0,57PT) 27A6-11E1-8000-D6217B60E588, 0x40, 0xF9FC0)

  Here, ApiEx (PNP0A08, PNP0A03, 0x0) indicates the root port 140 (PNP0A08) having a UID of 0 (0x0). PCI (0x1, 0x0) indicates a PCI card 34n (expansion card 150) corresponding to device number 1 (0x1) and function number 0 (0x0).

  The boot path analysis unit 123 is connected to the root port 140 of the UID indicated by this boot path, and the expansion card 150 mounted at the position where the device number and the function number match is used as the expansion card 150 used for starting the OS. Identify.

  When the boot path analysis unit 123 specifies the expansion card 150 used for OS startup, the link register setting unit 124 stores the expansion card 150 other than the expansion card 150 specified by the boot path analysis unit 123 and stored in the link register of the root port 140. All connection information is rewritten to Disable. That is, the link register setting unit 124 logically disconnects the expansion cards 150 other than the expansion card 150 specified by the boot path analysis unit 123 (step S6). The logical disconnection of the expansion card 150 by the link register setting unit 124 can be made by performing a process such as PCI Hot Delete when the expansion card 150 is a PCI card, for example. Thereby, the initialization process of the expansion card 150 by the option ROM 151 of the expansion card 150 that does not correspond to the boot path used for starting the OS is not performed.

  Next, the POST execution unit 125 reads the option ROM 151 from the expansion card 150 whose connection information stored in the link register of the root port 140 indicates “Enable” (logically connected), and stores the initial value stored in the option ROM 151. The program is sequentially executed (step S7). At this time, the POST execution unit 125 scans the external storage medium connected to the expansion card 150 to be initialized. Note that the processing of this step is executed on the order of several seconds to several tens of seconds, and therefore the effect on the startup time due to the number of expansion cards 150 mounted is large.

  When the POST execution unit 125 completes initialization of all the expansion cards 150 whose connection information stored in the link register of the root port 140 indicates “Enable”, the link register setting unit 124 rewrites the connection information to “Disable” in step S6. The connection information of the expansion card 150 is rewritten to Enable. That is, the link register setting unit 124 logically connects the expansion cards 150 other than the expansion card 150 specified by the boot path analysis unit 123 (step S8). Note that the logical connection of the expansion card 150 by the link register setting unit 124 can be made by performing a process such as PCI Hot Add when the expansion card 150 is a PCI card, for example. As a result, the expansion card 150 can be used during the operation of the information processing apparatus 100. Then, the CPU 120 reads out the OS from the external storage medium connected to the expansion card 150, and activates the OS (step S9).

  On the other hand, when the automatic activation determination unit 122 determines in step S3 that the automatic activation information indicates an invalid value (for example, a NULL value or a predetermined value indicating that automatic activation is not performed) (step S3: NO), The POST execution unit 125 reads the option ROM 151 from the expansion card 150 whose connection information stored in the link register of the root port 140 indicates “Enable” (logically connected), and stores the initialization program stored in the option ROM 151. Sequentially executed (step S10). Then, the CPU 120 reads out the OS from the external storage medium connected to the expansion card 150, and activates the OS (step S9).

FIG. 4 is a schematic block diagram showing a software configuration of the CPU 120 when the OS is executed.
When the OS is activated, the CPU 120 includes a boot path registration unit 126 and an automatic activation setting unit 127 in addition to the BIOS configuration.
The boot path registration unit 126 registers a boot path indicating the location of the expansion card 150 used for starting the OS in the nonvolatile memory 110 via the I / O unit 121.
When the OS is automatically started, the automatic start setting unit 127 rewrites the automatic start information stored in the nonvolatile memory 110 with the information of the OS.
That is, the automatic start information stored in the nonvolatile memory 110 is registered by the function of the OS after the CPU 120 starts the OS.

  As described above, according to the present embodiment, the information processing apparatus 100 acquires the boot path of the OS that performs automatic startup from the nonvolatile memory 110 and initializes the expansion card 150 indicated by the boot path. That is, the information processing apparatus 100 starts up the minimum expansion card 150 required for starting up the OS. Specifically, as the preprocessing for initializing the expansion card 150, the information processing apparatus 100 logically disconnects the expansion cards 150 other than the expansion card 150 used for starting the OS that performs automatic startup. To do. Thereby, regardless of the configuration of the information processing apparatus 100, startup can be speeded up.

  Further, according to the present embodiment, the information processing apparatus 100 logically connects the expansion card 150 that has been logically disconnected in the pre-initialization process of the expansion card 150 after the initialization. As a result, the information processing apparatus 100 can use the expansion card 150 during and after the activation of the OS.

As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to
For example, in the present embodiment, the configuration in which the information processing apparatus 100 includes one root port 140 has been described. However, the present invention is not limited to this, and the information processing apparatus 100 may include a plurality of root ports 140.

  In the present embodiment, the case where the POST execution unit 125 sequentially executes the initialization program of the expansion card 150 in which the connection information stored in the link register indicates “Enable” has been described, but the present invention is not limited thereto. For example, when the POST execution unit 125 initializes a certain expansion card 150, it is the same expansion card 150 that stores the initialization program, and the connection information stored in the link register indicates Enable. If there is another expansion card 150, the other expansion card 150 may be initialized using the same initialization program. Thereby, it is possible to prevent the same type of initialization program from being started many times.

  Moreover, although this embodiment demonstrated the case where BIOS was memorize | stored in the non-volatile memory 110, BIOS was delivered to the information processing apparatus 100 via a communication line, and the information processing apparatus 100 which received this delivery performs the said BIOS. You may do it.

  Moreover, although this embodiment demonstrated the case where BIOS was a program for implement | achieving the function mentioned above, it is not restricted to this. For example, the nonvolatile memory 110 stores a program and a general BIOS for realizing some of the functions described above (for example, the automatic activation determination unit 122, the boot path analysis unit 123, and the link register setting unit 124). The information processing apparatus 100 may realize the above-described functions by combining these. That is, the nonvolatile memory 110 may store a part of the functions described above as a so-called difference file (difference program).
