Driver\services start type directive
The driver\services start type directive is a service installation setting requirement for all display drivers. Windows Display Driver Model (WDDM) drivers are Plug and Play (PnP) and therefore must be demand started, where StartType =3.
For example:
; Service Installation Section
;
[R200_Service_Inst]
ServiceType = 1 ; SERVICE_KERNEL_DRIVER
StartType = 3 ; SERVICE_DEMAND_START
ErrorControl = 0 ; SERVICE_ERROR_IGNORE
LoadOrderGroup = Video
ServiceBinary = %12%\r200.sys
