![]() The 1394ohci.sys bus driver is fully backward compatible with the legacy 1394 bus drivers. In Windows 7 and later versions, the legacy port/miniport bus drivers are replaced by 1394ohci.sys, a monolithic IEEE 1394 bus driver that is implemented by using the kernel-mode driver framework (KMDF). Before Windows 7, the bus driver was a combination of a port driver (1394bus.sys) and a primary miniport driver for the motherboard's host controller (ochi1394.sys). The device driver communicates with the device by sending IRPs, which are processed by the IEEE 1394 bus driver. ![]() ![]() The bus driver provides a hardware-independent interface to the IEEE 1394 bus. The following diagram illustrates the IEEE 1394 driver stack with the new 1394 bus driver and the Microsoft-supported 1394 client drivers.Ī client driver for a device that connects to the IEEE 1394 bus driver sits on top of the IEEE 1394 driver stack.
