摘　　要：基本输入/输出系统(BIOS)是现代计算机系统的重要组成部分,负责计算机系统的开机自检、板级初始化、加载操作系统内核以及基本I/O功能。以龙芯2F CPU架构为研究背景,在其基础上分析了PMON的系统结构与工作流程,通过添加网络驱动程序,最终实现通过PMON加载Linux和VxWorks操作系统。进行必要的功能完善与性能优化,并经过严格的测试以排除可能存在的深层次缺陷,实现了一个性能稳定、功能完善、高可靠性的能与国产龙芯2F处理器平台紧密搭配的BIOS。Basic input/output system （BIOS） is an important component of current computer systems, which controls computers POST, board-level initialization, loading operating systems and basic I/O functions. Based on the research background of Loongson- 2F CPU, the system structure and working flow of PMON are analyzed. The loading of Linux and Vxworks operating systems was realized by adding a network driver. The necessary function perfection and performance optimization were carried out. The reliable and stable BIOS which can match the Loongson-2F CPU platform made in China was achieved.
