hi, mobilevil
    how can you tell two button?
    I use the DRIVER_GLOBALS space to record which button was pressed. But
when my driver read this memory space(after boot.bin),the GWES.EXE will get
an error.This memory space is in Driver Globals Area.
So I want to know how can you know which button was pressed?
And what is the trouble with my driver?

Thanks .
Fred
