Embodiment Construction

[0009] The BIOS setting value switching system of the present invention realizes the function of switching between different BIOS setting values ​​according to actual needs by presetting and storing different BIOS setting values. Storing two sets of BIOS setting values ​​and switching between the two sets of BIOS setting values ​​will be described as an example.

[0010] Please refer to figure 1 , in a preferred embodiment of the present invention, the BIOS setting value switching system includes a south bridge chip 10 , a storage unit 20 , a switch unit 30 and a BIOS chip 50 . The south bridge chip 10 is connected to the storage unit 20 and the switch unit 30 , and is connected to the BIOS chip 50 through a bus. The storage unit 20 includes a first read-only memory 22 and a second read-only memory 24, the first read-only memory 22 and the second read-only memory 24 are respectively used to store the first set of BIOS settings and the second Two sets of BIOS settings. The s...

Abstract

The invention relates to a system for switching BIOS set values, which comprises a South Bridge chip, a storage unit, a switch unit and a BIOS chip, wherein the South Bridge chip is connected with thestorage unit and the switch unit and is connected with the BIOS chip through a bus; the storage unit is used for storing a plurality of sets of preset BIOS set values; the switch unit controls the South Bridge chip to selectively read a set of BIOS set values from the storage unit, and writes the set values in the BIOS chip. The system for switching BIOS set values can switch among different BIOSset values.

Description

technical field [0001] The invention relates to a BIOS (Basic Input Output System, Basic Input Output System) setting value switching system. Background technique [0002] Generally speaking, various setting values ​​of the BIOS, real time clock and system boot settings are stored in the built-in CMOSRAM (Complementary Metal Oxide Semiconductor Random-access Memory, Complementary Metal Oxide Semiconductor Random-access Memory) on the motherboard. Its memory capacity is about 128-256 bytes, and the BIOS settings include: CMOS settings (such as: date, time, floppy disk drive, hardware timing and display mode, etc.), CPU (central processing unit, central processing unit, etc.) Device) speed, frequency and operating voltage settings, temperature protection settings, chipset settings, power management settings, plug and play and peripheral device connection interface configuration settings, system activation sequence Setting, computer hardware password setting, user password set...
