基于UEFI Shell的Pre-OS Application的开发与研究

UEFI(统一可扩展固件接口)是Intel提出的下一代PC Bios(Basic Input/Output System)架构。由于其除了完成传统Bios硬件启动检测和初始化等功能外,还构建了一个C语言执行环境,可以调用设备驱动,不用依赖操作系统就能在UEFI Shell的环境下进行磁盘管理和启动管理,以PC操作系统的备份为例,重点探讨UEFI Shell下无须操作系统的实现一般Application的方法和原理。

UEFI（Unified Extensible Firmware Interface） is next generation Bios（Basic Input/Output System） Architecture which promoted by Intel.Except implementation legacy Bios function,UEFI setup advanced language excutive environment,can directly recall device driver and acess Disk Boot management without OS supported.With above advantage,try to discuss the UEFI Application development theory,apply UEFI into PC OS back up,do the research on backup without OS supported principle and way
