Dear All,

I develop a layered driver in windows 2000. It use IoGetDeviceObjectPointer
£¨£©to get the deviceObject of lower device. And use
IoBuildDeviceIoControlRequest£¨£©to build my own IRP_MJ_DEVICE_CONTROL. And
use IoCallDriver() to send the IRP to the lower device. It works well in win
2000.

But when I install it in win98. I find that the IoCallDriver will return
STATUS_INVALID_PARAMETER and the lower driver don't recieve the IRP build by
higher driver. I am puzzled by this. And could any body show me some light
on that.

Best Regards!
Jing Feng
