Abstract

The present invention provides a computer turn-on system. It includes local computer, remote computer and communication link positioned between local computer and remote computer. It is characterized by that the described remote computer has a transmit unit, in the described transmit unit a starting program file capable of making the described local computer be come into normal working state is stored. The described local computer has a prestarting unit, after the local computer is powered on, said prestarting unit can initialize internal memory and initialize the described communication link so as to make local computer can download starting program file from remote computer interior. Correspondently, the invented computer turn-on method includes the following steps: powering on the local computer; initializing internal memory of local computer; creating communication link between local computer and remote computer; local computer can utilize the described communication link to download starting program file from remote computer and execute the described starting program file.

Description

technical field [0001] The invention relates to a computer system, in particular to a computer opening system and opening method. Background technique [0002] In a computer startup system, the Basic Input / Output System (BIOS), which is used to enable the computer to be used normally, is essential. BIOS is a set of programs in the ROM chip on the computer motherboard, which provides the lowest-level and most direct hardware control for the computer. BIOS is mainly used to store: self-diagnosis test program, system self-test loading program, system setup program, I / O driver program and interrupt service program of major I / O devices. When turning on or restarting every time, BIOS will run automatically to complete the turning on of the computer. For example, when the computer is powered on, because the computer has a BIOS, the system can check the various internal devices, that is, the power-on self-test (POST) process, and finally ensure that the computer is turned on norma...
