Method of switching between normal and time-limited startup of computer based on system bios

Abstract

The invention discloses a method for switching between normal and time-limited computer startup based on the system BIOS, using the startup mode CMOS setting program embedded in the system BIOS to complete the normal and time-limited startup interchange, multi-period startup start time and machine time parameter configuration ;Release the program embedded in the system BIOS to intercept the INT 1CH interrupt when booting within a limited time to complete multi-period machine time timing and control; the remaining space of the CMOS RAM storage body is used for intermediate data storage during limited time booting. The notable feature of the present invention is that there is no need to load the timing switch software on the operating system. When the time-limited power-on prohibition and enable setting items are set to enable, there is another special hotkey to directly enter the system BIOS when starting the computer. Mode CMOS parameter setting program completes multi-period boot start time and machine use time parameter modification or temporarily releases normal boot flag setting, which has the advantages of easy operation and flexible 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.
