Problems solved by technology

[0007] In the traditional computer system 100, when the CPU 102 is down, the computer system 100 cannot perform a software reset action, but can only perform a hardware reset action to complete a cold boot
However, when the computer system 100 completes the cold boot, the data stored in the SDRAM 104 and the settings of the computer system 100 by the user before the computer system shuts down will completely disappear.
For the user, the user must reset the computer system 100, which is a waste of time, and important data is likely to be lost, causing serious damage to the user.

Embodiment Construction

[0022] In order to make the above-mentioned purposes, features, and advantages of the present invention more obvious and understandable, a preferred embodiment is specifically cited below, and in conjunction with the accompanying drawings, the detailed description is as follows:

[0023]The main spirit of the method for warm booting or cold booting applied to a computer system of the present invention when the central processing unit is down is that when the CPU is in a down state, the computer system detects that a user wants to execute Hardware reset function or software reset function. Then, restart the CPU by performing a hardware reset operation. Then, when the user chooses to execute the hardware reset function, the data and setting values ​​of the SDRAM are cleared, so that the computer system returns to the default state. And when the user chooses to execute the software reset function, the hardware reset action is regarded as an action to replace a software reset act...

Abstract

It is a cool or warm computer starting method when the CPU doesn't work, which is used in computer system with a CPU and a memory. The method comprises the following steps: first to check the user executes hardware reset function or software reset function; then to restart the CPU by use of a hardware reset operation; when user chooses hardware reset function, it clears the data and set in the memory and makes the computer restore to the pre-set status; when user chooses software reset function, the computer stores the data and set in the memory to store the computer to the pre-set state before the system dies.

Description

technical field [0001] The present invention relates to a booting method and its computer system, and in particular to a booting method capable of warm booting or cold booting when a central processing unit is down and its computer system. Background technique [0002] Generally speaking, a computer system provides a hardware reset function and a software reset function to enable the computer system to perform a cold boot and a warm boot respectively. When the computer system crashes, the user can select a hardware reset function and a software reset function to restore the computer system to normal. [0003] Wherein, the software reset function is to perform a system reset action in a software manner. However, when the computer system crashes even the central processing unit (CPU) of the computer system and cannot execute software instructions, the software reset function cannot be used. The hardware reset function refers to performing an action of resetting the computer ...
