为什么，IRQ8也不能触发呢？我上辈子做错了什么！

    代码如下：
   在这段代码里，俺除了钩挂IRQ8以外可什么都没干，你们可都看到的。可为不行，\VtoolsD\example\cpp\hwint 却可以,Why?


//IRQ8.h-----
#define DEVICE_CLASS IRQ8Device
#define IRQ8_DeviceID UNDEFINED_DEVICE_ID
#define IRQ8_Init_Order UNDEFINED_INIT_ORDER
#define IRQ8_Major 1
#define IRQ8_Minor 0
#define MY_IRQ     8

class MyHwInt : public VHardwareInt
{
public:
MyHwInt():VHardwareInt(MY_IRQ,0,0,0){};
virtual VOID OnHardwareInt(VMHANDLE);
};

class IRQ8Device : public VDevice
{
public:
virtual BOOL OnSysDynamicDeviceInit();
virtual BOOL OnSysDynamicDeviceExit();
MyHwInt* pMyIRQ;
};

class IRQ8VM : public VVirtualMachine
{
public:
IRQ8VM(VMHANDLE hVM);
};

class IRQ8Thread : public VThread
{
public:
IRQ8Thread(THREADHANDLE hThread);
};




// IRQ8.cpp - main module for VxD IRQ8

#define DEVICE_MAIN
#include "IRQ8.h"
Declare_Virtual_Device(IRQ8)
#undef DEVICE_MAIN



IRQ8VM::IRQ8VM(VMHANDLE hVM) : VVirtualMachine(hVM) {}

IRQ8Thread::IRQ8Thread(THREADHANDLE hThread) : VThread(hThread) {}

BOOL IRQ8Device::OnSysDynamicDeviceInit()
{
pMyIRQ = new MyHwInt();
if(pMyIRQ&&pMyIRQ->hook())
{
pMyIRQ->physicalUnmask();
return TRUE;
}
else return FALSE;

}

BOOL IRQ8Device::OnSysDynamicDeviceExit()
{
if(pMyIRQ) delete pMyIRQ;
return TRUE;
}


VOID MyHwInt::OnHardwareInt(VMHANDLE hVM)
{
dprintf("I am waiting for you…………");
sendPhysicalEOI();
}
