Computer, and computer startup management system and method thereof

Abstract

The invention relates to a computer, and a computer startup management system and method thereof. The computer startup management system comprises a control module, a timing circuit, a switching circuit and a complementary metal oxide semiconductor (CMOS) clearing circuit, wherein the control circuit is in a basic input / output system (BIOS) and outputs a first control signal through a general purpose input / output (GPIO) interface, and the first control signal is at a first level in startup and triggered into a second level when the BIOS definitely can normally finish running is determined by the setting of the first control signal; the timing circuit is used for receiving the first control signal, timing and outputting a second control signal when the first control signal is still kept at the first level till the first predetermined time TH; the switching circuit is used for immediately switching off a main board power supply when the second control signal is received; and the CMOS clearing circuit is used for constantly lowering real time clock reset (RTC RST) signals at a third predetermined time TJCC period when the second control signal is received and after a second predetermined time TD is delayed so as to clear CMOS. By implementing the system and the method, the CMOS setting of the last normal startup can be automatically recovered without any manual operation or intervention, and the system is restarted.

Description

technical field [0001] The present invention relates to computers, and more specifically, to a computer boot management system, a computer including the computer boot management system and a method for boot management in the computer. Background technique [0002] Parameter The important resource configuration parameters of the computer are recorded. Incorrect CMOS parameter settings may cause the computer to fail to start normally. At this time, it is necessary to manually clear the CMOS to make the computer start normally. The steps to manually clear the CMOS: ①. Lithium battery powering CMOS or short circuit clearing CMOS jumper, the second step needs to open the case to operate on the computer motherboard. However, customers often do not know that they can manually clear the CMOS to allow the computer to start normally, and often report computer failures by mistake, increasing the customer service costs of computer manufacturers. In addition, industrial computers are n...
