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] This method of offline burning BIOS requires a long time for burning, and the cost of burning modules for burning BIOS is high, and the situation of artificially missing burning 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.

Embodiment Construction

[0013] see figure 1 , is a system composition diagram of the BIOS online burning method, a BIOS online burning system, which includes a board 15 to be burned, a single-chip microcomputer main control burning card 30, a PC mainframe 40 and an SFC server 50. This board 15 to be burned is a main board, and a target BIOS 10 to be burned is pasted on it. There is a burning platform on this single-chip microcomputer main control burning card 30, and this board 15 to be burned is placed on it, links to each other with this single-chip microcomputer main control burning card 30 by some probes (not shown). The microcontroller main control flash card 30 is connected to the PC host 40 via a serial port, and the PC host 40 communicates with the SFC server 50 through a network.

[0014] After the target BIOS 10 to be burned is mounted on the board 15 to be burned, data signals, address signals, control signals, and power are transferred to the board 15 to be burned through the single-chip...

Abstract

The on-line read-in method for BIOS includes the following steps: firstly, mouniting a BIOS to be read in on a plate to be read in; then using a chip microprocessor to receive read-in command and automatically switch on power supply; making blank check of BIOS, if said blank check is not successful, erasing said BIOS, making on-line read-in of BIOS, utilizing chip microprocessor to read the data signal and address signal into said BIOS, then checking said BIOS and automatically switching off power supply.

Description

【Technical field】 [0001] The invention relates to a BIOS programming method, in particular to a BIOS online programming method capable of online programming, which is simple to operate, saves programming time and prevents artificial missed programming. 【Background technique】 [0002] In the computer system architecture, BIOS (Basic Input Output System) is the most basic software in the basic operation of the computer system. The BIOS is mainly composed of a series of low-level instruction sets, which are responsible for controlling the basic input and output of the personal computer, system setting information, power-on self-test program, system startup program and the work coordination of the internal hardware of the system. The role of the BIOS in the personal computer is very important. . Generally speaking, the BIOS program is burned in a non-volatile memory that does not need power for a long time, and this type of BIOS memory is built into the motherboard of the compu...
