![]() The 1394ohci.sys bus driver also uses the values that are specified in generation and max_rom entries of the node's configuration ROM header to improve the retrieval of the remaining content of the configuration ROM. ![]() ![]() The legacy 1394 bus driver uses asynchronous quadlet reads at S100 speed-or 100 megabits per second (Mbps). The new 1394 bus driver tries to use asynchronous block transactions at faster bus speeds to retrieve the contents of a node's configuration ROM. The status of the completed I/O request is in the IRP. You can provide an I/O completion routine that is called after the request is complete. This behavior differs from that of the legacy 1394 bus driver, in which certain I/O requests complete immediately.Ī client driver must wait until I/O requests sent to the new 1394 bus driver are complete. ![]() This is not a redistributable driver that you can download separately.Īll I/O requests that are sent to the new 1394 bus driver return STATUS_PENDING because the 1394ohci.sys bus driver is implemented by using KMDF instead of WDM. It is automatically loaded when you install a 1394 controller. The 1394ohci.sys driver is a system driver that is included in Windows. ![]()
