Description
|
Many Windows 95 driver models, such as IOS (for disk drivers) and the network, support dynamically loaded device drivers. These VxDs are not loaded by the VMM32 real-mode loader, but are loaded by a device loader that is responsible for loading and initializing the drivers at the correct time and in the correct order.
For example, for SCSI adapter miniport drivers, the device loader is *IOS. The entries for a SCSI adapter are found in this Registry key:
Hkey_Local_Machine\System\CurrentControlSet\Services\Class
Because there is no StaticVxD=xxx line in this Registry entry, the VMM32 real-mode loader does nothing when Windows 95 identifies this device.
Configuration Manager attempts to find any device node that has a DevLoader= entry in the Registry. The device loader (in the previous example, *IOS) examines the Registry, finds the PortDriver= entry, loads the driver and any associated support drivers, and initializes the adapter.
