This article describes an issue that occurs when you use a FireWire port-based device in Windows 8.1 or Windows 8. Additional steps of configuration is required to enable this update after the installation.

Symptoms

All equipment facilities installed on HP EliteBook 8470p are listed below. In order to facilitate the search for the necessary driver, choose one of the Search methods: either by Device Name (by clicking on a particular item, i.e. AMD Radeon HD 7500M/7600M Series) or by Device ID (i.e. PCI VEN1002&DEV6841). In order to facilitate the search for the necessary driver, choose one of the Search methods: either by Device Name (by clicking on a particular item, i.e. Intel (R) Active Management Technology - SOL) or by Device ID (i.e. HP EliteBook 2540p laptop features 68 devices.

Assume that you have a computer that equips with an IEEE 1394 FireWire controller card. After you upgrade the computer from Windows 7 to Windows 8.1 or Windows 8, devices that connect to the computer by using a FireWire port do not work.

After you upgrade the computer from Windows 7 to Windows 8.1 or Windows 8, devices that connect to the computer by using a FireWire port do not work. Cause This issue occurs because the legacy 1394 bus drivers (1394bus.sys and Ochi1394.sys) are removed in Windows 8.1 or Windows 8.

Additional package information

• This driver is only intended to work with legacy 1394 host controllers. Therefore, you may experience lower transfer data rates than the 1394b driver.

• The driver is intended to resolve compatibility issues for 1394 peripherals on 1394b systems. If you are not experiencing these issues, you should continue to use inbox drivers that are provided in Windows 8.1 or Windows 8.

• You have to reinstall this stand-alone driver package if you upgrade to a newer operating system version in the future.

For more information about software update terminology, click the following article number to view the article in the Microsoft Knowledge Base:

824684 Description of the standard terminology that is used to describe Microsoft software updates

Microsoft Windows contains three system-supplied storage port drivers:

• Storport Driver (Storport.sys), available in Windows Server 2003 and later versions of the operating system (recommended)

• SCSI Port Driver (Scsiport.sys)

• ATA Port Driver (Ataport.sys), available in Windows Vista and later versions of the operating system

The Storport driver is a more efficient, higher performance driver than SCSI Port. Therefore you should develop miniport drivers that work with the Storport driver whenever possible. It is particularly important to use Storport with high performance devices, such as host-based RAID and fibre channel adapters. Storport cannot be used with adapters or devices that do not support Plug and Play (PnP) or that must use system DMA. For a detailed list of restrictions on the use of the Storport driver, see Requirements for Using Storport with an Adapter.

The ATA port driver shields an ATA miniport driver from the SCSI-based protocol that the port driver uses to communicate with higher-level drivers, such as storage class drivers. For instance, miniport drivers that are attached to either SCSI port or Storport must provide SCSI sense data to the port driver. This is not necessary for an ATA miniport driver. The ATA port driver collects the necessary data from the ATA miniport driver by using ATA commands, organizes the data so that it conforms to a SCSI sense data format, and passes the data on to higher-level drivers as though it were SCSI sense data. The ATA port driver also converts each SCSI_REQUEST_BLOCK that it receives from higher-level drivers into an ATA-based equivalent called an IDE_REQUEST_BLOCK.

Each port driver communicates with a set of vendor-supplied storage miniport drivers and supplies a set of support routines for the miniport drivers to call. Each port driver communicates with its miniport drivers by calling a standard set of routines that every storage miniport driver must implement. The miniport driver routines called by the SCSI port driver, the Storport driver, and the ATA port driver are very similar to one another. Lists of port driver support routines and miniport driver routines can be found in the following sections:

If you want your storage device to be supported on client Windows products, or on server products earlier than Windows Server 2003, you must supply a SCSI Port miniport driver.

Drivers Elite Port Devices Replicator

If you want your storage device to be supported on Windows Server 2003 and later versions of the server product family, you can provide either a Storport miniport driver or a SCSI miniport driver. If you wish to install an ATA storage device in Windows Vista and later versions of the operating system, you must provide an ATA port miniport driver.

The sections that follow describe the Storport, SCSI Port, and ATA port drivers and how they differ.
