摘　　要：论述了在 Windows9x系统中设计开发出虚拟设备驱动程序 Vx D,其与 Windows9x操作系统一样工作在系统的核心级 ( ring0级 ) ,能与底层硬件 ISA总线进行实时、准实时通信与控制。利用 Vx D读出 ISA总线 I/O口上的数据并存入一个自定义缓冲区内 ,然后通过 ring0与 ring3的通信准实时将采集到的数据送到工作在This paper decribes how the virtual device driver is devised and developed in the Windows 9x system. The virtual device driver functions in the same kernel level as Win9x operation system (ring0 level). Moreover, it can exchange data with rock bottom hardware of computer? ISA bus duly and punctually . One can utilize VxD to read out the data of I/O interface of ISA bus and store them in a self defining buffer, and then deliver the data to the programme processing data of ring3 for punctual displaying spectrum by mutual communication of ring3 and ring0.
