Switching method for realizing normal and time limited startup of computers based on system BIOS

Abstract

The invention discloses a switching method for realizing normal and time limited startup of computers based on a system BIOS. A startup mode CMOS setting program in an embedded system BIOS is utilized to complete parameter configuration of switching of normal and time limited startup as well as multi-period startup starting time and use time; the program intercepting INT lCH interruption in the embedded system BIOS is released to complete multi-period use time timing and control when in time limited startup, and the residual space of a CMOS RAM memory stack is used for storing intermediate data of time limited startup. The switching method has the obvious characteristics that timing startup and shutdown software does not need loading on an operating system; when time limited startup is forbidden and an enabling set item is set as enabling, another special hotkey exists for directly entering the startup mode CMOS parameter setting program of the system BIOS to complete parameter modification of multi-period startup starting time and use time or temporarily release normal startup marking setting when computers are started. The switching method is easy to operate and flexible to use.

Description

technical field [0001] The invention belongs to the technical field of computer control, and relates to a time-limited working method of a computer, in particular to a switching method based on a system BIOS to realize a normal start-up of a computer and a time-limited start-up. Background technique [0002] At present, personal computers have been popularized in families and have become an important tool for the majority of young people to study and entertain. However, teenagers are prone to lack of self-control. Teenagers are addicted to computer games and the Internet for a long time, which will seriously affect their learning and healthy growth. Therefore, it is necessary to control the time teenagers use computers. Although some existing timing switch software plays a time-limiting effect, because it is built on the software on the operating system, it is easy to turn it off, and it is difficult to achieve the purpose of effectively controlling teenagers' use of compute...

However, teenagers are prone to lack of self-control. Teenagers are addicted to computer games and the Internet for a long time, which will seriously affect their learning and healthy growth. Therefore, it is necessary to control the time teenagers use computers

Although some existing timing switch software plays a time-limiting role, it is easy to turn off because it is a software built on the operating system, and it is difficult to effectively control the use of computers by teenagers.

There are also many control methods through external hardware, but the cost is high.

The other is through the CMOS setting method of the motherboard BIOS, but this method can only set a certain time to turn on or off, and does not have a time-limited function, nor can it play a time-limited role.
