Framework so that network startup device is difficult to be applicable on the machine of different instruction set and framework, lacks versatility.
It is another to have by the way of explanation perform script is downloaded to support the startup scheme of multiple network system, but the program needs
Additionally to increase a read-only storage (ROM) or EPROM (E PROM) on a client, simultaneously
Need advance burning in memory be used for perform script system or interpretive program, this method be add client computer into
This, while the complexity of client computer startup stage is added, this method, which needs to increase, allows host CPU to go to perform the machine of system in ROM
System, or the system gone using extra CPU in execution ROM, because most of client computer are not dedicated for depositing this
The ROM of system, also go to run the mechanism of the ROM without specially design CPU, cause this method to lack versatility.
The content of the invention
It is an object of the invention to provide a kind of method of network start-up operation system, to adapt to various different instructions
The multiple operating system starting problem of the hardware platform of collection and framework, while support the selection of different operating system to start.
Technical solution of the present invention is as follows：A kind of method of network start-up operation system, comprises the following steps successively：
S1, client computer obtain IP address；
S2, the kernel file from first server the first operating system of download；
S3, the kernel file of the first operating system perform and the file system of the operating system of carry first, client computer pass through
The file system starts the first operating system therein, and first operating system reads the menu text on second server
Part, there is provided the menu for the second operating system for needing to run to client computer selection；
S4, client computer selection need the second operating system run；
S5, the first operating system are downloaded from second server and run the second operating system of client computer selection simultaneously.
Further, first operating system only includes being used to provide automatic or user mutual formula selection startup menu
Application program, support support library file during application program operation and for performing selection system kernel or starting text
The associative operation order of part.
Further, during the acquisition IP address, support PXE BIOS to obtain IP by PXE protocol, do not support PXE's
BIOS sets IP manually.
Further, it is described from first server download the first operating system kernel file when, be supplied to by PXE protocol
The filename of client computer first server IP address and kernel file.
Further, the first server and second server are same server.
Further, the first server and second server are different server.
Further, the client computer selects to be selected by user by the input equipment of client computer during the second operating system
Select.
The advantages of technical scheme provided by the present invention, is：By down operation system kernel and run on a network
The first operating system rather than network startup device the selection of the activation system of user is provided, first operating system is one
Micro operation system, effectively solve network startup device may be brought for the machine of different instruction set and framework it is incompatible
Problem, while increase any extra hardware device also without client computer, it is not required that CPU Initiated Mechanism is changed, as long as
Network is supported to solve the problems, such as network startup and network startup multiple operating system.Other can be eliminated using the inventive method
Extra expense caused by Starting mode and the versatility for increasing network startup system schema, can set not increasing any hardware
Reach unitized multisystem selection in the case of standby to start.
Brief description of the drawings
Fig. 1 is the schematic diagram of network start-up operation systems approach.
Embodiment
With reference to embodiment, the invention will be further described, but not as a limitation of the invention.
Incorporated by reference to shown in Fig. 1, the method for network start-up operation system, comprise the following steps：
S1, for supporting PXE or not supporting PXE BIOS, the former can be by straight by PXE protocol, the latter
The mode for connecing setting sets the IP address of client computer；
PXE agreement is to obtain IP address information by DHCP protocol, and DHCP protocol is client computer by sending DHCP
Discovery information is broadcast in whole LAN, and the Dynamic Host Configuration Protocol server in LAN can be sent after the message is received
