User is by pressing power knob (or touching mouse or keyboard etc.) input operation system start-up/wake up up
Instruction.Hereafter, process enters step S402.
In step S402, it may be judged whether enable security password.Such as, user can be beforehand through by institute
The security password stating display floater 32 display arranges user interface, is made whether to enable setting of security password
Put.
If obtaining positive result in step S402, enable security password, then processed and enter step
Rapid S403.
In step S403, controller is based on checking user interface idsplay order, display checking user interface.
Such as, the T-con 302 in described display floater 32 calls a few frame pictures prestored in its ROM
(checking user interface), and on described display floater 32, show described checking user interface.Hereafter,
Process enters step S404.
In step s 404, the password to be verified via checking user interface input is obtained.Such as, user
Described checking user interface based on display, inputs password to be verified by described keyboard 34.Hereafter, place
Reason enters step S405.
In step S405, transfer the security password being stored in the first processing unit.Such as, described
EC 31 transfers the security password prestored in its safe flashing 301.Hereafter, process enters step S406.
In step S406, it is judged that whether password to be verified mates described security password.Such as, described
EC 31 will input the peace prestored in password to be verified and its safe flashing 301 via described keyboard 34
Full password performs comparison.
If obtaining positive result in step S406, i.e. input password to be verified via described keyboard 34
Mate with the security password prestored in safe flashing 301, then process and enter step S407.
In step S 407, the first processing unit guides the second processing unit to start.Such as, described EC
Described for guiding CPU 33 is completed os starting/wake up up by 31.
If on the contrary, obtain negative decision in step S406, i.e. treated via the input of described keyboard 34
Checking password does not mates with the security password prestored in safe flashing 301, then process and enter step
S408。
In step S408, the first processing unit controls to close electronic equipment.Such as, described EC 31
Password authentification will be terminated, and control to close described electronic equipment.
Returning step S402, if obtaining negative decision in step S402, the most not enabling safety close
Code, then process and proceed directly to step S407, and described for guiding CPU 33 is completed operation system by described EC 31
System starts/wake up up.
After step S407, i.e. after os starting/wake up up, process can enter step S409.
In step S409, control display security password and user interface is set.Such as, described CPU 33
Described display floater 32 can be controlled and show that security password arranges user interface.User is based on described in display
Security password arranges user interface, by described keyboard 34 other input-output equipment such as (or) mouses,
Described security password is configured and revises.Described EC 31 in response to described security password arrange and
Amendment, arranges and whether enables described security password and/or revise described security password.
