在oallib/intr/intr.c里使能了外部中断：

OALIntrStaticTranslate(SYSINTR_ETH, IRQ_EINT15);  value = IRQ_EINT15; OALIntrEnableIrqs(1, &value);

注册网卡能成功，注册中断也能成功，代码如下：
    NdisZeroMemory (&Characteristics, sizeof (Characteristics));     Characteristics.MajorNdisVersion = (UCHAR)SMSC9118_NDIS_MAJOR_VERSION;     Characteristics.MinorNdisVersion = (UCHAR)SMSC9118_NDIS_MINOR_VERSION;     Characteristics.CheckForHangHandler = Smsc9118CheckForHang;     Characteristics.DisableInterruptHandler = smscDisableIntr;     Characteristics.EnableInterruptHandler = smscEnableIntr;     Characteristics.HaltHandler = Smsc9118Halt;     Characteristics.HandleInterruptHandler = Smsc9118HandleInterrupt;     Characteristics.InitializeHandler = Smsc9118Initialize;     Characteristics.ISRHandler = Smsc9118Isr;     Characteristics.QueryInformationHandler = Smsc9118QueryInformation;     Characteristics.ReconfigureHandler = NULL;     Characteristics.ResetHandler = Smsc9118Reset;     Characteristics.SendHandler = NULL;     Characteristics.SetInformationHandler = Smsc9118SetInformation;     Characteristics.TransferDataHandler = NULL;     Characteristics.ReturnPacketHandler = Smsc9118GetReturnedPackets;     Characteristics.SendPacketsHandler = Smsc9118SendPackets;     Characteristics.AllocateCompleteHandler = NULL;       Status = NdisMRegisterMiniport (gSmsc9118MiniportBlock.NdisWrapperHandle,                                      &Characteristics,                                      sizeof (Characteristics));     if (Status == NDIS_STATUS_SUCCESS)     {         SMSC_TRACE0(DBG_INIT, "NdisMRegisterMiniport OK.\r\n");     } －－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－     status = NdisMRegisterInterrupt (&(pAdapter->Interrupt),                                      pAdapter->hMiniportAdapterHandle,                                       (UINT)pAdapter->ucInterruptNumber,                                       (UINT)0xf,                                       (BOOLEAN)TRUE,                                      (BOOLEAN)TRUE,                                                                           NdisInterruptLatched);       if (status == NDIS_STATUS_SUCCESS)     {         SMSC_TRACE0(DBG_INIT,"  Interrupt Connected\r\n");         }

当有中断来时，在common/intr/intr.c里能打印出中断号，但是始终进不了我的中断服务程序，而且，中断一来就被屏蔽了。

请问：可能是什么地方出了问题？

，问题不在代码，在注册表，在注册表里网卡的相应位置增加一个对应的中断号就可以了：

    "SysIntr"=dword:23
