[0006] In the above-mentioned Preboot Execution Environment (PXE), when the operating system of the computer obtains the IP address of the DHCP server, the DHCP server supports IPV4&IPv6 address technology and stores it in the Network File System (Network File System) via TCP / IP network remote access. , NFS), when the computer performs remote boot, after downloading the complete system core and the network card driver (the network DHCP client driver is mainly based on IPv4, and then perform actions according to whether there is IPv6 requirement, if If the IPv4 protocol does not exist, the DHCP client driver will stop), and will execute the action of requesting the DHCP server to obtain the DHCP IP address. Or (IPv4+IPv6) address request, if the DHCP server only supports IPv6 (not including IPv4) address, then the computer cannot obtain the IPv4 IP address from the DHCP server, and cannot download operating system files from the DHCP / TFTP server Executing the remote boot action greatly limits the operating experience of the server and computer that support the pure (Pure) IPv6 address technology to achieve remote boot

Embodiment Construction
[0028] The remote boot method of the present invention supports IPv6 technology with high address capacity to realize remote boot through TCP / IP remote access network file system, solves the problem of lack of network address resources, and improves user experience.
[0029] see figure 1 , is a flow chart of the method for remote booting of the present invention, as shown in the figure, the method includes the following steps:
[0030] Step 11: Burn the standard Preboot Execution Environment (PXE) code into the computer;
[0031] Step 12: The basic input output system (Basic Input Output System, BIOS) of the computer specifies that the computer should be booted by the network card;
[0032] Step 13: execute the basic input output system, judge whether to perform a remote boot in the basic input output system, if so, go to step 14, if not, then go to step 13 and continue to judge whether to perform remote boot;
[0033] Step 14: The computer executes the program of the enviro...

The invention discloses a remote boot method. The method is used for remotely controlling a computer to boot. The remote boot method comprises the steps that standard preboot execution environment programme code is burnt in the computer; a basic input output system of the computer appoints a network card to guide the computer to boot; the basic input output system is executed, and whether to carry out remote boot or not is judged; when it is determined that the remote boot needs to be executed, the computer executes a preboot execution environment programme to drive the network card; the network card sends MAC addresses of the computer and a request for obtaining IP addresses to a server; the computer executes trivial file transfer protocol code and sends a dynamic host configuration protocol request to the server, and the server sends a response and allocates the IP addresses corresponding to the MAC addresses; and the computer receives the IP addresses and downloads and executes a network bootstrap programme on the server, thereby guiding the computer to enter an operating system.
Description
[0001] 【Technical field】 [0002] The present invention relates to a method for remote start-up, in particular to a method for realizing remote start-up only supporting IPV6 technology. [0003] 【Background technique】 [0004] In the management of current computer systems, remote boot has gradually become an indispensable method and device. The current hardware architecture of remote boot can use the Preboot Execution Environment (PXE) standard module on the network card. (Standard Module) to implement remote booting. The action principle of this method is to burn a standard PXE program code into the Boot ROM of the network card of the computer or the BIOS of the motherboard. When the computer is turned on, the computer will be executed by the BIOS. If the computer has been set to be started by PXE, the BIOS will hand over the next execution right to the PXE program code, that is, execute the PXE program. When the PXE program obtains the execution right, it will drive the netw...
