Abstract
A power-on error detection system and method applicable in an electronic device having a motherboard is proposed, wherein the motherboard is provided with a memory for storing a BIOS program and a signal outputting unit. The power-on error detection system and method are used to indicate an operation state of the electronic device while the electronic device reads the BIOS program at power-on and performs a POST (Power-on self-test) process. A first warning signal output command is set in the a segment of the BIOS program. The first warning signal output command drives the signal outputting unit to output a first warning signal after the electronic device is turned on and executes the POST process according to the BIOS program stored in the memory.
Claims20
A power-on error detection system applicable in an electronic device having a motherboard, wherein the motherboard is provided with a memory for storing a BIOS (Basic Input Output System) program, and wherein the power-on error detection system is for indicating an operation state of the electronic device when the electronic device reads the BIOS program at power-on and performs a POST (Power-on self-test) process, the power-on error detection system comprising:
- a CPU (Central Processing Unit) functioning as a control kernel of the motherboard, and electrically connected with the memory of the motherboard, the CPU being configured for executing the POST process according to the BIOS program stored in the memory at power-on of the electronic device, wherein the BIOS program comprises a first warning signal output command stored in a first segment of the BIOS program;
- and
- a signal outputting unit electrically connected with the CPU, the signal outputting unit being driven to output a first warning signal by the first warning signal output command of the BIOS program when the CPU executes the POST process.
A power-on error detection method applicable in an electronic device having a motherboard, wherein the motherboard is provided with a memory for storing a BIOS program and a signal outputting unit, the power-on error detection method for indicating an operation state of the electronic device when the electronic device reads the BIOS program at power-on and performs a POST (Power-on self-test) process, the method comprising the steps of:
- setting a first warning signal output command in a first segment of the BIOS program;
- and
- driving the signal outputting unit by the first warning signal output command of the BIOS program to output a first warning signal when the electronic device is turned on and performs the POST process.
