Abstract

The invention discloses a computer device, a program writing method and a program reading method, and belongs to the technical field of computers. The computer device comprises a central processing unit (CPU), a basic input / output system (BIOS) chip, a storage chip and a programmable logic device (PLD), wherein the CPU is connected with the BIOS chip through the PLD, and the storage chip is connected with the PLD; the PLD is used for receiving a BIOS program sent by the CPU; a character string stored in the storage chip is read; the BIOS program is converted according to the character string so as to obtain a converted BIOS program, the converted BIOS program is stored into the BIOS chip, and the converted BIOS program is different from the BIOS program before conversion. The problem thatthe original BIOS program is stored in the BIOS chip, and accordingly the safety of the original BIOS program is low is solved, and the effect of improving the safety of the BIOS program in the BIOS chip is achieved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a computer device, a program writing method and a program reading method. Background technique [0002] A computer device usually includes components such as a central processing unit (Central Processing Unit, CPU), an internal memory, an external memory, and a network interface. Various components are installed in specific positions on the motherboard and communicate with each other through the bus. The motherboard is usually a rectangular circuit board, on which are installed the main circuit systems that make up the computer equipment, such as Basic Input Output System (Basic Input Output System, BIOS) chip, I / O (Input / Output) control chip, indicator light connector , expansion slots, DC power supply connectors and other components. The BIOS chip has the characteristic that stored data will not be lost after power failure, and may be a read-only memory (Read-Only...
