This article was previously published under Q268743 SYMPTOMSHalAssignSlotResources returns STATUS_INVALID_PARAMETER_3 if the DeviceObject parameter is NULL.
CAUSEHalAssignSlotResources is obsolete and is exported only to support existing drivers. Drivers of Plug and Play (PnP) devices are assigned resources by the PnP Manager, which passes resource lists with each IRP_MN_START_DEVICE request.
On a computer running Windows 2000, all the bus-related hardware abstraction layer (HAL) functions are patched to call the actual bus driver. Because the bus driver tracks resources on a PDO basis, the system needs a device object to simulate (fake) a PDO.
RESOLUTION
You must specify a device object when you use HalAssignSlotResources.
STATUS
This behavior is by design.
