摘　　要：针对xPC双机型实时系统中目标机启动过程中需要软驱的问题,研究了的无软驱启动方法。首先研究了xPC双机型实时系统的工作原理和目标机的启动过程,分析各种启动模式的特点,然后采用虚拟软驱技术并结合USB总线启动、硬盘启动以及网络启动三种方法研究了实现无软驱启动解决方案,阐述了这几种方法的特点。最后试验表明三种方法都能够实现无软驱启动目标机,证明所研究方案的有效性,从而提高了xPC目标机启动的可靠性和速度。In the xPC real-time environment with host and target computers, floppy disk is generally required to boot the target computer. To overcome this trouble, alternative methods without the floppy disk were studied. Firstly, the working principle of real-time xPC with host/target computer and the boot process of the target computer were studied, and different target boot modes were examined. Secondly, virtual floppy drive was used to study the solutions of achieving booting the target computer without floppy disk in combination with three substitutes, i. e. USB bus, hard disk and LAN, and the characters of these methods were explicated. Finally, through the tests it showed that the target computer could be booted with any one of the three methods, which indicated the effectiveness of the proposed schemes, so the reliability and the speed of the booting process of xPC target computer has been improved.
