6.1.1 Commonly Implemented Dispatch Routines

In general, most NT drivers must handle some or all of the following requests:

The Dispatch routine entry points that any NT driver must set in its driver object vary according to the type and functionality of the underlying physical device. For device-type-specific information about IRP major function codes that NT device drivers must handle, see the Kernel-Mode Driver Reference. For information about SCSI and video miniport drivers, see Appendix A and the Kernel-Mode Graphics Driver Guide, respectively. For more information about other types of SCSI drivers, see also Appendix A.
