BIOS on line burning writing system

Abstract

The present invention relates to a BIOS on-line chip-reading system, including a chip-reading machine, a BIOS on-line chip-reading card, a plate to be chip-red and a BIOS to be chip-red which is placed on the plate to be chip-red. The described BIOS on-line chip-reading card includes a power supply circuit, a series interface communication circuit, a chip microprocessor, a first buffer, a second buffer, a third buffer, a mother BIOS and a connector. Besides, said invention also provides their connection mode and working principle of said system.

Description

【Technical field】 [0001] The invention relates to a burning system, in particular to a BIOS online burning system capable of burning BIOS online, which is simple to operate, saves burning time and prevents artificial missed burning. 【Background technique】 [0002] BIOS (Basic Input Output System, Basic Input Output System) is a program programmed into the read-only chip of the motherboard, responsible for controlling the basic input and output of the personal computer, system setting information, power-on self-test program, system startup program and system internal The work of each hardware is coordinated, and the role of the BIOS in a personal computer is very important. Therefore, once the BIOS is damaged by a virus such as CIH, or the user accidentally updates the BIOS and causes damage, the personal computer cannot be turned on at all. At this time, the BIOS needs to be reprogrammed. [0003] Existing BIOS programming is to use a burner to burn before the BIOS chip is ...

AI Technical Summary

Problems solved by technology

For example, Chinese patent application No. 02204313.6 discloses a programmable IC burner, which includes a burner unit on which a programmable integrated circuit chip is installed. However, the burner can only burn Record integrated circuit chips that have not been assembled, and cannot burn integrated circuit chips that have been integrated on the motherboard

[0004] It takes a long time to burn the BIOS chip offline, and the cost of the burning module used to burn the BIOS is high, and the situation of artificially missing programming often occurs, thus increasing the test cost

In addition, the BIOS chip needs to be sucked with a special vacuum suction pen, and the burning operation is also quite troublesome

Moreover, when programming the BIOS in TSOP and other packaging forms, its pins are easily damaged, resulting in an increase in the defective rate of the motherboard when the BIOS chip is soldered to the motherboard.
