摘　　要：在嵌入式软件系统开发中,为了能够快速正确地引导操作系统,需要有一个功能强大的Bootloader来支持。PMON是一种针对嵌入式系统而开发的操作系统引导程序,其作用在于初始化嵌入式硬件系统的外设以便能够正确引导、启动操作系统。基于PMON开发移植的目的,从研究PMON的架构出发,深入研究PMON的编译环境及其执行流程,在此基础上,通过向PMON中添加网卡驱动代码,并验证了网卡驱动工作的正确性,最终实现了PMON下的网卡驱动移植。To boot the operating system quickly and correctly, a powerful bootloader is needed during the development of the embedded software system. PMON is a bootstrap program designed for embedded system, and it＇s used to initialize the devices on the hardware system, after that, the operating system could boot validly. Based on the purpose of developing and transplanting of the PMON , the compile environment and executing process of PMON are researched deeply from the view of the basic PMON＇s framework. On this basis, add the Network driver to PMON and verify the correctness of the network driver. Ultimately, the transplant of the network device is finished correctly.
