Description
Technical field
The present invention relates to UEFI System guides to start method and technology field, in particular to a kind of UEFI guidance system open more
Dynamic system and method.
Background technique
One, the meaning of UEFI: UEFI is a kind of standard that style interface is described in detail.This interface is used for operating system certainly
The dynamic operating environment from pretrigger is loaded into a kind of operating system.
Two, the difference of UEFI and BIOS: UEFI is a kind of so-called " firmware ", is responsible for doing hardware-initiated and inspection in booting
The work such as survey, and serve as intermediary role when operating system controls hardware；Compared with BIOS, UEFI coding 99% is all by C
Language is completed；UEFI change before interruption, hardware port operation method, and use Driver/protocol new side
Formula；UEFI will not support X86 real pattern, and directly adopt Flat mode (namely cannot with DOS, some present EFI or
UEFI can be because done compatibility, but actually this part is not belonging to defining for UEFI)；UEFI output is also no longer simple
Binary system code, be changed to Removable Binary Drivers；OS starting is no longer to call Int19, but directly utilize
protocol/device Path；For third-party exploitation, BIOS does not accomplish substantially, except the design of non-participating BIOS, but
It is also to be limited by the size of ROM, and UEFI conveniently benefit.UEFI makes up that BIOS is insufficient to the support of new hardware to be asked
Topic.
Three, dramatically different with BIOS, UEFI is with modularization, the parameter stack transfer mode of C language style, dynamic
The form of link constructs system, it is more easily implemented than BIOS, and fault-tolerant and error correction characteristic is also stronger, so as to shorten system research and development
Time.More importantly it is that it runs on 32 or 64 bit patterns, breaches the addressability of traditional 16 codes, reach
The maximum address of processor, this measure overcome bios code and run slow drawback.
System mode is guided relative to traditional BIOS, UEFI BIOS guides system mode more and more common.UEFI guidance
Process is opening initialization UEFI, then, operating system is directly guided, into system.It is compared with traditional BIOS guidance, UEFI
The process of one of BIOS self-test has been lacked in guidance, so booting will more faster, this also becomes the new lover of computer.For UEFI
BIOS system guidance is also required to a variety of starting methods, increases starting reliability.
Wherein the start-up course of UEFI includes that SEC (protected mode of security setting CPU), PEI (are initialized before EFI
PEI), DXE (execute driving, install Device handle, install protocol), BDS (startup equipment selection), TSL are (temporary
Property system be loaded into), several stages such as RT (runing time).
PXE (preboot execute environment, Pre-boot Execution Environment) is developed most by Intel Company
New technology works in the network mode of Client/Server, and work station is supported to download image from remote server by network,
And thus support that, by network startup operating system, during startup, demanding terminal server distributes IP address, then uses TFTP
(trivial file transfer protocol) or MTFTP (multicast trivial file transfer
Protocol) agreement is downloaded a starting software package and is executed into local memory, completes terminal (client by this starting software package
End) basic software setting, thus the terminal operating system that guidance is pre-installed in server.
To sum up, it is proposed that a kind of more starting methods of UEFI can solve the problems, such as follows: there is computer local bootstrap
With two kinds of system Starting mode of netboot.
Summary of the invention
In order to solve problems in the prior art, the present invention provides a kind of more activation systems of UEFI guidance system and sides
Method can choose local disk and be booted up or network startup method, if local disk starting is timely when something goes wrong
To solution.Increase the method and startup stability of the starting of UEFI system simultaneously.
The technical solution adopted in the present invention is as follows:
A kind of more activation systems of UEFI guidance system, including local disk are booted up module and netboot starting mould
Block, in system starting process, Selection utilization local disk is booted up module starting respectively, or is started using netboot
Module starting, wherein the selection priority that local disk is booted up module is greater than netboot starting module, when the sheet
When local disk is booted up module damage, just selection carries out system starting using netboot starting module.
It includes that local disk BootLoader reading unit and UEFI guide execution unit that local disk, which is booted up module,
The local disk BootLoader reading unit is used to read when Selection utilization local disk is booted up module starting
BootLoader in local disk；The UEFI guidance execution unit is used for, and reads the BootLoader in local disk
Afterwards, guidance UEFI executes system by SEC, PEI, DXE, BDS, TSL, RT each stage and starts.
Netboot starting module includes BootLoader acquiring unit, and PXE and network interface card information acquiring unit, UEFI are virtual
Disk obtains registering unit and UEFI is booted up unit, and the BootLoader acquiring unit is used for, when Selection utilization net
When network is booted up module starting, according to the IP address that DHCP is obtained, client is downloaded by TFTP connection server end
The BootLoader of UEFI；The PXE and network interface card information acquiring unit obtains the PXE of the machine for executing BootLoader
And network interface card information, it is communicated with server end foundation；The UEFI virtual disk obtains registering unit and is used for, and client is from service
UEFI virtual disk is downloaded and is loaded at device end, is registered in UEFI；The UEFI is booted up unit and is used for, and reads this earth magnetism
After BootLoader in disk, guidance UEFI executes system by SEC, PEI, DXE, BDS, TSL, RT each stage and starts.
A kind of more starting methods of UEFI guidance system, comprising the following steps:
A, in system starting process, select the mode of starting: local disk is booted up or netboot starting；
B, according to Starting mode priority, five-star local disk is selected to be booted up first；
If C, local disk is booted up failure, netboot is selected to start.
Step B is specifically included:
BootLoader in B1, reading local disk；
B2, guidance UEFI execute system by SEC, PEI, DXE, BDS, TSL, RT each stage and start.
Step C is specifically included:
C1, the IP address obtained according to DHCP, client download UEFI's by TFTP connection server end
BootLoader；
C2, BootLoader is executed, obtains the PXE and network interface card information of the machine, communicated with server end foundation；
UEFI virtual disk is downloaded from server end and loaded to C3, client, registers in UEFI；
C4, BootLoader continue read execute booting operating system file, guidance UEFI by SEC, PEI, DXE,
BDS, TSL, RT each stage execute system and start.
Technical solution provided by the invention has the benefit that
Using the more activation systems and method of a kind of UEFI guidance system of the invention, UEFI starting method can be realized
When diversity, a kind of Starting mode are obstructed, system Starting mode can be switched, to increase the reliability of system starting.
