Abstract: When developing Extensible Firmware Interface (EFI) applications, the native file system of EFI can not support various file systems. This paper analyses the structure and the component of EFI file system and puts forward a 3-layer model for EFI NTFS file system scheme according to the features of EFI file system. How to implement EFI file system in the form of EFI dirver is introduced and the basic functions of NTFS are implemented on the EFI .

Key words: Extensible Firmware Interface(EFI), NTFS, EFI driver

摘要： 在可扩展固件接口(EFI)平台的应用开发中，本地文件系统难以支持多种文件系统。该文分析了EFI文件系统的结构和组成，根据其特点，提出3层结构模型的EFI NTFS文件系统设计方案，阐述如何以EFI驱动形式实现EFI文件系统。实现了EFI环境下NTFS文件系统的基本功能。
