Problems solved by technology

[0004] At present, in the process of booting the OS image by the BIOS through the network, the interface binding function of multiple network cards has not been realized. The loading path is single, and only a certain fixed network port is used, resulting in poor reliability and fault tolerance. If the fixed network port or network path Fault, the whole system cannot start

Embodiment Construction

[0019] figure 1 It is a flowchart of a method for loading an operating system image provided by an embodiment of the present invention. Such as figure 1 As shown, the method provided in this embodiment includes:

[0020] Step 11: The BIOS of the source host obtains the communication address of the host; the host is a host communicating with the source host, and the source host has multiple network ports.

[0021] The source host has multiple network cards, and each network card has a network port. Therefore, the source host with multiple network cards has multiple network ports. In the embodiment of the present invention, the network port is a network card interface. A source host with multiple network cards can be a server with multiple network cards. The communication connection between the source host and the host may specifically be a connection between a network port of the source host and a network port of the host. The BIOS in the embodiment of the present inventio...

Abstract

The invention provides a method for loading operation system images and a basic input and output system. The method comprises steps that an input and output system of a source host obtains a communication address of a host machine; the host machine is in communication connection with the source host machine which is provided with a plurality of internet accesses; the input and output system selects one available internet access from all the internet accesses of the source host machine to serve as a working internet access and enables the available internet accesses except for the working internet access to be in non-working states; and the input and output system loads the operation system images from the host machine according to the working internet access and the communication address of the host machine. The basic input and output system (BIOS) achieves a function of binding interfaces of multiple network cards in the process of loading the operation system (OS) images through networks.

Description

technical field [0001] Embodiments of the present invention relate to communication technology, and in particular to a method for loading an operating system image and a basic input and output system. Background technique [0002] In order to improve the availability, reliability and network throughput of the network connection of the server, the industry is researching a link aggregation (link aggregation or trunking) technology of bonding multiple network card interfaces together. The multi-network card interface bonding technology gathers two or more physical network cards together to form a single pseudo-Ethernet device, also known as a bonding device, and then an IP address is assigned by the system administrator. The system considers these aggregated NICs as one NIC. Therefore, the bonding device can configure its IP like any network card. Moreover, all network card devices in the bonding device have the same hardware (MAC) address, and the client will naturally trea...
