Alternatively, methods described also includes：The hard disk bound is cancelled and bound.
Hard disk secure provided in an embodiment of the present invention start the detailed process of method and hard disk binding method as shown in figure 3,
Mainly include the following steps that：
Step S31：Receive start-up command.System electrification, carry out normal hardware initialization action.
Step S32：Judge whether to enter hard disk binding configuration interface.Whether detection user has the binding of configuration hard disk or configuration
Hard disk cancels the requirement of binding, in this way into step S33, judges whether to set licencing key, otherwise into step S47, sentences
Whether disconnected hard disk set binding.
Step S33：Judge whether to set licencing key.For hard disk is tied on the mainboard of industrial computer, herein
Licencing key is the access password of industrial control computer mainboard, only knows the user of licencing key and could carry out the binding of hard disk and mainboard
Set or cancel binding and set.Enter step S34 if licencing key was set, licencing key is inputted, otherwise into step
S35, licencing key is set and preserved.
Step S34：Input licencing key.User's input licencing key is bound or cancelled to hard disk binding and sets
Put.
Step S35：Licencing key is set and preserved.
Step S36：Configuration mode selects.User's selection is into hard disk binding pattern or enters cancellation binding pattern.
Step S37：Into cancellation binding pattern.
Step S38：Cancel binding to set.After having carried out cancelling binding setting, into step S45, bound cancelling
Instruction be sent to the firmware of hard disk.
Step S39：Into binding pattern.
Step S40：Manual configuration password is judged whether to, input password is set manually into step S41, user in this way
Initial value, password initial value is otherwise automatically generated at random into step S42, BIOS.
Step S41：User sets input password initial value manually.
Step S42：BIOS automatically generates password initial value at random.
Step S43：Store in the flash memory that password initial value is reserved to BIOS.User is set manually the password of input initial
The password initial value that value or BIOS are automatically generated at random is saved in the reserved flash memories of BIOS.
Step S44：BIOS generates clear crytpographic key.It is close by the generation decryption of certain algorithm according to above-mentioned password initial value
Code.Above-mentioned password initial value is that user is inputted to obtain by button, and by algorithm obtain clear crytpographic key, therein one
A little codes can not be inputted by button, i.e., some codes are not present on button, can not be tasted on button by different
Examination carrys out strength decryption, so that the system is difficult the decryption that is cracked.
Step S45：Send an instruction to hard disk firmware.The instruction for being bound hard disk based on clear crytpographic key is sent to hard disk
Firmware.
Step S46：System reboot.The weight of system is carried out after the binding for having carried out hard disk sets or cancelled binding to set
Open, jumped to after restarting and start step operation.
Step S47：Whether hard disk, which carried out binding, is set.Hard disk is first determined whether in the normal boot process for carrying out hard disk
Set, set if carrying out binding, it is encryption hard disk to illustrate the hard disk, then carries out following with whether mainboard carried out binding
Automatic decrypting process, initially enter step S48, obtain the password initial value in BIOS flash memory.Bound if not done by crossing
Set, it is non-encrypted hard disk to illustrate hard disk, then can directly carry out the startup of hard disk, i.e., normally be opened into step S51, system
It is dynamic.
Step S48：Obtain the password initial value in BIOS flash memory.Obtain and be stored in BIOS in hard disk binds setting up procedure
Password initial value in flash memory.
Step S49：Clear crytpographic key is generated according to password initial value.The password initial value obtained according to upper step passes through certain
Algorithm generates clear crytpographic key, and the algorithm is consistent with generating the algorithm of clear crytpographic key in hard disk binding procedure.
Step S50：Clear crytpographic key and instruction are sent to hard disk firmware.
Step S51：System normally starts.
