What Determines When a Driver Is Loaded • • 3 minutes to read • Contributors • • In this article Before exploring when and how file system drivers are loaded during the system boot sequence, it is necessary to understand driver start types and load order groups. Driver Start Types A kernel-mode driver's start type specifies whether the driver is to be loaded during or after system startup. There are five possible start types: SERVICE_BOOT_START (0x00000000) Indicates a driver started by the operating system (OS) loader. File system filter drivers commonly use this start type or SERVICE_DEMAND_START. On Microsoft Windows XP and later systems, filters must use this start type in order to take advantage of the new. SERVICE_SYSTEM_START (0x00000001) Indicates a driver started during OS initialization. This start type is used by the file system recognizer.

Qawwali is a vibrant musical tradition that stretches back more than 700 years. Dholak software. Originally performed mainly at Sufi shrines throughout the subcontinent, it has also gained mainstream popularity.

Except for the file systems listed below under 'SERVICE_DISABLED,' file systems (including network file system components) commonly use this start type or SERVICE_DEMAND_START. This start type is also used by device drivers for PnP devices that are enumerated during system initialization but not required to load the system. SERVICE_AUTO_START (0x00000002) Indicates a driver started by the Service Control Manager during system startup. SERVICE_DEMAND_START (0x00000003) Indicates a driver started on demand, either by the PnP Manager (for device drivers) or by the Service Control Manager (for file systems and file system filter drivers). SERVICE_DISABLED (0x00000004) Indicates a driver that is not started by the OS loader, Service Control Manager, or PnP Manager.

Used by file systems that are loaded by a file system recognizer (except when they are the boot file system) or (in the case of EFS) by another file system. Such file systems include CDFS, EFS, FastFat, NTFS, and UDFS. Also used to temporarily disable a driver during debugging. Specifying Start Type A driver writer can specify the start type for a driver at installation time in either of the following ways: • By specifying the desired start type for the StartType entry in the service-install-section referred to by an directive in the driver's INF file. This method is described in ServiceInstall Section. • By passing the desired start type for the dwStartType parameter when calling CreateService or ChangeServiceConfig from a user-mode installation program. This method is described in the reference entries for CreateService and ChangeServiceConfig in the Microsoft Windows SDK documentation.

Driver Load Order Groups Within the SERVICE_BOOT_START and SERVICE_SYSTEM_START start types, the relative order in which drivers are loaded is specified by each driver's load order group. Drivers whose start type is SERVICE_BOOT_START are called boot (or boot-start) drivers. On Microsoft Windows 2000 and earlier systems, most filters that are boot drivers belong to the 'filter' group.

On Microsoft Windows XP and later systems, filters that are boot drivers generally belong to one of the new FSFilter load order groups. These load order groups are described in detail in. Advanced reinforced concrete design by p.c. varghese free download free.

Driver whose start type is SERVICE_SYSTEM_START are also loaded in the order of the load order groups to which they belong. However, no system-start driver is loaded until after all boot drivers have been loaded. Note Load order groups are ignored for drivers whose start type is SERVICE_AUTO_START, SERVICE_DEMAND_START, or SERVICE_DISABLED. A complete, ordered list of load order groups can be found under the ServiceGroupOrder subkey of the following registry key: HKEY_LOCAL_MACHINE System CurrentControlSet Control The same load group ordering is used for SERVICE_BOOT_START and SERVICE_SYSTEM_START drivers.
