AI Technical Summary

Problems solved by technology

But no matter using the above-mentioned single or two independent BIOS memories, it is impossible to solve the problem that once the single BIOS bus connected to the computer system is damaged or has a problem, the mechanism of BIOS backup and exchange will not be able to function at all, and in serious cases The computer system will not be able to do the initial boot detection

Embodiment Construction

[0025] figure 1 Illustrated is a schematic diagram of a computer system according to an embodiment of the present invention. Please refer to figure 1 , the computer system 100 includes a CPU 110 , a chipset 120 , a first bus 130 , a second bus 140 , a first memory 150 , a second memory 160 and a logic control circuit 170 .

[0026] The chipset 120 is coupled to the CPU 110 . The first bus 130 and the second bus 140 are coupled to the chipset 120 . The first memory 150 is coupled to the chipset 120 through the first bus 130 for storing a first Basic Input Output System (BIOS for short).

[0027] The second memory 160 is coupled to the chipset 120 through the second bus 140 for storing the second BIOS. The logic control circuit 170 is used to detect and control the chipset 120 according to the state of the first bus 130 to select to access the first memory 150 via the first bus 130 or to select to access the second memory 160 via the second bus 140 .

Abstract

The invention discloses a computer system comprising a CPU, a chip packet, a first bus, a second bus, a first memory, a second memory and a logic control circuit. The chip packet is coupled to the CPU. The first and second buses are individually coupled to the chip packet. The first memory is coupled to the chip packet via the first bus to store a first basic input and output system. The second memory is coupled to the chip packet via the second bus to store a second basic input and output system. The logic control circuit is to detect and control the chip packet to select to access the first or the second memory via the first or second bus according to state of the first bus.

Description

technical field [0001] The present invention relates to a computer system, and in particular to a computer system with dual Basic Input Output System (BIOS) and an operation method thereof. Background technique [0002] Basic Input Output System (BIOS) is the most basic mainboard system stored in flash memory (Flash Memory), which is mainly used to set the hardware settings and some related parameters of the mainboard. As we all know, this kind of data is very important and cannot be destroyed, otherwise it will lead to the situation that the motherboard cannot be turned on normally or some functions cannot be used normally. In view of this, in some traditional technologies, a computer system with an auxiliary BIOS has been proposed to solve the problem that the computer system cannot be started normally when a single BIOS is damaged. [0003] However, in today's computer systems with auxiliary BIOS, the control mechanism of BIOS automatic backup switching is only designed ...
