The Research And Development Of VXD In Windows Environment

This dissertation analyzes the building and realization of virtual environment in the Windows9X operating system,and have a in-depth research to the Virtual Device Driver Model VXD in Windows environment. By analysis of different characteristic and development method when VXD access different hardware resources, a driver program and application program based on the data gathering card with ISA interface is discussed, the design of the driver program solves the problem to a certain extent of instability in interrupt and DMA way when VXD access hardware resource, making the data gathering card running well. Thus this dissertation has strong practical significance.Chen GuoHua(Computer Application Technology )Directed by prof. Zheng Ling...
