When the electronic device is started and hardware is initialized, the electronic device initializes the hardware whether a program can be loaded or not, namely, a driver corresponding to the hardware is operated. Due to more programs, such as Network stack: network management Protocol (MNP), Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), DHCP Protocols, block input/output interface (BlockIO), disk input/output interface (diskoo), file system (Filesystem), and the like. Therefore, if all hardware is initialized, it takes a long boot time. In order to solve the technical problem, in the embodiment of the invention, the hardware meeting the preset condition is not initialized in the starting process of the electronic equipment, that is, the initialization process of some hardware is omitted, so that the starting time is saved. The embodiment of the invention is applied to electronic equipment, and the electronic equipment can comprise desktop computers, notebook computers, servers and other equipment.
Fig. 1 is a flowchart of a first embodiment of a boot method of the present invention, and as shown in fig. 1, the boot method of this embodiment may specifically include the following steps:
and S101, acquiring hardware information during startup.
S102, if the hardware information shows that the hardware does not meet the preset initialization condition, in the initialization stage, ignoring the hardware.
Wherein the hardware information comprises:
whether the hardware has a pre-boot execution environment and iSCSI;
when there is a pre-boot execution environment and iSCSI, the pre-boot execution environment and the state of the interfaces of iSCSI.
The Preboot execution Environment (PXE) is a technology developed by Intel corporation, works in a network mode of Client/Server, supports a workstation to download images from a remote Server through a network, and thus supports starting an operating system through the network, during the starting process, a terminal requires the Server to allocate an IP address, and then downloads a start software package into a local memory for execution by using a simple File Transfer Protocol (TFTP) or a multi-point File Transfer Protocol (MTFTP), and the start software package completes the setting of the basic software of the terminal (Client), thereby guiding the terminal operating system pre-installed in the Server.
The iSCSI technology is a SCSI command set developed by IBM corporation and developed by The Internet Engineering Task Force (IETF) corporation, which is used by hardware devices and can run on The upper layer of The IP protocol, and this command set can implement The SCSI protocol running on The IP network, enabling routing on, for example, a high-speed gigabit ethernet network. iSCSI technology is a new storage technology that combines the existing SCSI interface with Ethernet (Ethernet) technology to allow servers to exchange data with storage devices using IP networks. The iSCSI Interface, Internet Small Computer System Interface (iSCSI), is a TCP/IP-based protocol used to establish and manage the interconnections between IP storage devices, hosts, clients, etc., and to create a Storage Area Network (SAN). SANs enable the SCSI protocol to be applied to high-speed data transfer networks, with such transfers occurring at block-level across multiple data storage networks. The SCSI architecture is based on a client/server model, which typically applies to environments: the devices are in close proximity to each other and the devices are connected by a SCSI bus. The primary function of iSCSI is to perform the encapsulation and reliable transfer of large amounts of data between a host system (i.e., initiator) and a storage device (i.e., target) over a TCP/IP network. In addition, iSCSI provides for encapsulating SCSI commands over an IP network and runs over TCP.
Therefore, when the hardware has a pre-boot execution environment and iSCSI, and the state of the iSCSI interface is a pass-through state, the hardware can connect with a DHCP server through its Firmware (Firmware) and initialize the hardware, in other words, the initialization operation of the hardware is performed through its own Firmware rather than during the process of booting a basic input/Output System (BIOS), and the initialization of the hardware and the initialization process of the BIOS can be performed synchronously, so the time for initializing the whole hardware can be greatly shortened.
As shown in fig. 2, when the electronic device starts up the operating system, the Basic Management Controller (BMC) starts up simultaneously when the BIOS system starts up, and the Controller calls a Management Component Transport Protocol (MCTP) and a Platform Level Data Model (PLDM) to detect a state of the hardware, where the MCTP can control a hardware device, and the PLDM can read information of the hardware or monitor the hardware. After acquiring the hardware information, when the BIOS runs to a Device Selection start (BDS) stage, the BMC may select to initialize the hardware or ignore the hardware according to whether the hardware information satisfies a preset initialization condition; for example, the server may use a Baseboard Management Controller (BMC) to perform this process. Then, a Power On Self Test (POST) stage is carried out.
According to the technical scheme of the embodiment, the hardware state is detected during startup, whether the hardware is initialized or not is determined according to the detection result, and when the detection result shows that the hardware does not meet the preset initialization condition, the hardware is ignored in the initialization stage, so that the startup time is shortened.
Fig. 3 is a flowchart of a second embodiment of the boot-up method of the present invention, which further describes the technical solution of the present invention in more detail based on the first embodiment. As shown in fig. 3, the booting method of this embodiment may specifically include the following steps:
s301, sending a request for obtaining the hardware information.
S302, receiving the hardware information sent by the interface of the hardware.
Wherein the hardware information comprises:
whether the hardware has a pre-boot execution environment and iSCSI;
when there is a pre-boot execution environment and iSCSI, the pre-boot execution environment and the state of the interfaces of iSCSI.
Wherein the firmware of the hardware is in communication with a remote server connection to initialize the hardware.
When the hardware has a pre-boot execution environment and iSCSI, and the state of the iSCSI interface is a pass state, the hardware may connect with a DHCP server through firmware (firmware) of the hardware and initialize the hardware, in other words, the initialization operation of the hardware is performed through firmware of the hardware, rather than during the process of booting a Basic Input/Output System (BIOS), and the initialization of the hardware and the initialization process of the BIOS may be performed synchronously. Thus, the time for starting up is greatly shortened.
When the electronic equipment starts the operating system, the BMC is started at the same time of starting the BIOS system, and the MCTP and the PLDM are called to detect whether the hardware is the hardware connected with the network, wherein the MCTP can control a hardware device, and the PLDM can read the information of the hardware or monitor the hardware. Then, when the BIOS runs to the BDS stage, the hardware is determined to be initialized or ignored according to whether the hardware information meets the preset initialization condition; for a server, a substrate controller may be employed to perform this process.
After the initialization of the hardware is completed, the BIOS system will proceed to the POST phase.
S303, when the hardware information indicates that a pre-boot execution environment exists and the iSCSI interface state is a connected state, ignoring the hardware in an initialization stage of booting the BIOS.
S304, if the hardware information indicates that the hardware does not have a pre-boot execution environment or the iSCSI interface state is a non-connected state, initializing the hardware in an initialization stage of booting a basic input output system.
Specifically, if the hardware information indicates that the hardware has a pre-boot execution environment or the iSCSI interface state is a connected state, it indicates that the current hardware is network hardware and can be connected to a DHCP server, and an initialization operation can be performed through the DHCP server. On the other hand, if the hardware information indicates that the hardware does not have a pre-boot execution environment or the iSCSI interface state is a non-connected state, it indicates that the current hardware is non-network hardware and cannot perform initialization operation through a DHCP server, and therefore, the hardware needs to be initialized during an initialization phase of booting the BIOS system.
Wherein, the states of the interface of the iSCSI and the boot execution environment can be detected by at least one of the following methods:
sending a request based on a device management protocol to the interface and receiving a response;
sending a platform-level data model to the interface, and receiving a response.
Wherein, whether the hardware has the pre-starting execution environment and the iSCSI is detected by the network module, which specifically comprises the following steps:
after the network module sends a request for transmitting a data packet, receiving a response sent by a dynamic host configuration protocol server, and determining whether a pre-boot execution environment and iSCSI exist according to the response;
wherein the data packet is transmitted through a firmware interface provided by a hardware service provider.
Specifically, Firmware may transmit data through the hardware system interface, and when receiving a request from the network module to communicate with the DHCP server through the transmitted data to confirm whether iSCSI, such as Option17, is in a connected state and PXE, such as PXE of code 60, is present.
The technical scheme of the embodiment initializes the hardware by communicating the firmware of the hardware with the DHCP server, and the process is synchronous with the starting process of the BIOS, so that the hardware initialization is finished, and the starting time is shortened.
Fig. 4 is a schematic diagram of a boot device according to a first embodiment of the present invention, as shown in fig. 4, the boot device of this embodiment may specifically include an obtaining module 41 and a determining module 42.
An obtaining module 41 configured to obtain hardware information when the computer is started;
the judging module 42 is configured to ignore the hardware in an initialization stage when the hardware information indicates that the hardware does not meet a preset initialization condition;
wherein the hardware information comprises:
whether the hardware has a pre-boot execution environment and iSCSI;
when the pre-boot execution environment and the iSCSI exist, the states of the interfaces of the pre-boot execution environment and the iSCSI are detected.
Further wherein the firmware of the hardware communicates with a DHCP server connection to initialize the hardware.
According to the technical scheme of the embodiment, the hardware state is detected during startup, whether the hardware is initialized or not is determined according to the detection result, and when the detection result shows that the hardware does not meet the preset initialization condition, the hardware is ignored in the initialization stage, so that the startup time is shortened.
An embodiment of the present invention further provides an electronic device, where the electronic device includes the boot apparatus shown in fig. 3.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
