The following registry entries allow you to configure the behavior of the port driver/SCSI miniport driver pair. For information about the PnpInterface registry entry required for all Plug and Play (PnP) devices, see Registry Entries for Plug and Play SCSI Miniport Drivers.

  • TimeoutValue

    • Location: HKLMSystemCurrentControlSetServicesDiskTimeoutValue

    • Motorola others driver download for windows 10. Values: 1 - 255 seconds

    • Meaning: Time in units of seconds before an SRB request initiated by the disk class driver will time out. If this registry value is not set, a default value of 10 seconds is used. Time-out values for requests that are initiated by class drivers vary according to the class driver.

      Note If the miniport sets a value, that timeout will be honored preferentially. The timeout selection logic is as follows:

      • Starting in Windows 8, if the miniport sets a timeout value (in HKLM … Services<miniport>ParametersIoTimeoutValue), this value is honored by the storage class driver.
      • Otherwise, if the disk global timeout registry (this key) is set, this value is honored by the storage class driver.
      • Otherwise, a default value of 10 seconds is used by the storage class driver.

    • Operating system version: This feature is available in all versions of the Windows operating systems.

The software will install the USB device driver for the I/Q OUT port and the ExtIO DLL file for the HDSDR. Thoroughly read the instruction guide before installing or updating the software. The IC-R8600 needs firmware version 1.30 or later to utilize the I/Q OUT port. All devices attached to your computer via USB need drivers to tell the computer what the device is and what can be done with it. The TH-D74 is no different. There are not electronics in the cable; however, there are electronics in the radio that allow it to connect to the computer.

  • TotalSenseDataBytes
    • Location: HKLMSystemCurrentControlSetEnum<Bus>< DeviceID><Device>DeviceParametersScsiPortTotalSenseDataBytes
    • Values: Between 18 and 255 for SCSI Port. Storport always uses 255.
    • Meaning: If set, this value designates the size in bytes of the buffer that the SCSI Port driver allocates for request sense data. If the value is not set, SCSI port uses a default size of 18. The Storport driver always allows 255. Warning: filter drivers that insert between the class driver and the port driver must respect this value and not attempt to manage the size of the sense data buffer.
    • Operating system version: This feature is available in Windows 2000 Server and later operating systems.
  • MaximumSGList
    • Location: HKLMSystemCurrentControlSetServices<ServiceName>ParametersDeviceMaximumSGList, where <ServiceName> = the miniport driver name specified with the AddServices directive in the INF file.
    • Values: Between 16 and 255.
    • Meaning: Indicates the number of scatter/gather list elements supported by the adapter.
    • Operating system version: This feature is available in Windows NT 4.0 SP4 and later operating systems.
  • BusType
    • Location: HKLMSystemCurrentControlSetServices<ServiceName>ParametersBusType, where <ServiceName> = the miniport driver name specified with the AddServices directive in the INF file.
    • Values: The same as STORAGE_BUS_TYPE enumerator:
    • Meaning: Indicates the type of bus that the adapter is connected to.
    • Operating system version: This feature is available in Windows 2000 and later operating systems.
  • CreateInitiatorLU
    • Location: <ServiceName>ParametersDeviceCreateInitiatorLU, where <ServiceName> = the miniport driver name specified with the AddServices directive in the INF file.
    • Values: Either 0 or 1.
    • Meaning: A value of 1 indicates that the port driver will create an 'initiator logical unit,' so that higher-level drivers can send certain requests to the port driver even though there is no actual hardware device connected to the adapter or the connected device is not visible to the system. Sometimes it is necessary to configure a device's operating parameters or update its firmware before it will be visible to the system. Prior to Windows Server 2003, it was not possible to instruct the port driver to update firmware for a device unless the port driver had at least one logical unit in its device stack. Some vendors attempted to remedy this deficiency by adding so-called 'pseudo-LUNs' to the adapter's stack, but this created problems for setup and disk management, and occasionally such solutions would cause the configuration manager to prompt the user for a driver for a non-existent device. With the new 'initiator logical unit' feature, it is no longer necessary to use these work-around techniques. By setting CreateInitiatorLU to 1 in the registry, you can send IOCTLs and WMI requests to the port driver whether it has devices attached that are visible to the operating system. Another use of the 'initiator logical unit' feature is to allow communication with fibre channel adapters that have a purely administrative function and no attached devices.
    • Operating system version: This feature is available in Windows Server 2003 and later operating systems. The value of this registry value only affects the functionality of the SCSI Port miniport drivers. Storport miniport driver always permit access to adapter objects, even when no device is attached to the adapter.

This topic describes the features of I8042prt, the Microsoft Windows 2000 and later system function driver for PS/2-style keyboard and mouse devices.

I8042prt implements the I8042prt service and its executable image is i8042prt.sys.

The features of I8042prt include:

Devices

Rt Systems Driver

  • Hardware-dependent, simultaneous operation of a PS/2-style keyboard and mouse device.

    The keyboard and mouse share I/O ports, but use different interrupts, interrupt service routines (ISR), and ISR dispatch completion routines.

  • Plug and Play, power management, and WMI

  • Operation of legacy devices.

  • Connection of a keyboard class service callback routine and a mouse class service callback routine.

    I8042prt uses the class service callback to transfer data from the input data buffer of I8042prt to the data buffer of the class driver.

  • Addition of a vendor-supplied PI8042_KEYBOARD_INITIALIZATION_ROUTINE callback routines for a keyboard device.

    An optional upper-level device filter driver provides the callback routines.

  • Addition of a vendor-supplied PI8042_KEYBOARD_ISR callback routine and a custom PI8042_MOUSE_ISR callback routine.

    Optional upper-level device filter drivers provide these callbacks routines.

  • Keyboard write buffer request and mouse write buffer request.

    An upper-level device filter driver can use write buffer requests to synchronize its writes to a device with the ISR of the device and other reads and writes on the device.

  • Keyboard start information request and mouse start information request.

    The start information request passes a pointer to an interrupt object of a device to an upper-level filter driver. The filter driver can use the interrupt object to synchronize its operation with the ISR of the device.

  • I8042prt callback routines.

    An upper-level device filter driver can use the callback routines in the context of the ISR of a device to write to a device, and to queue data packets from the device.

Registry settings associated with the PS/2 driver

The following is a list of registry keys associated with the PS/2 port driver.

  • EnableWheelDetection [REG_DWORD] – Determines whether the driver attempts to detect and enable the wheel on the mouse device. Some devices are equipped with a mouse wheel to provide rapid scrolling and other control features if supported by an application.
  • ResendIterations [REG_DWORD] – Specifies the maximum number of times a hardware operation is attempted. If the number of trials exceeds the value of this entry, Windows considers the operation to have failed.
  • NumberOfButtons [REG_DWORD] – Specifies the number of buttons on the mouse-port mouse at startup. If the number of buttons detected at startup is incorrect, you can override it by changing the value of this entry.
  • KeyboardDataQueueSize [REG_DWORD] – Specifies the number of keyboard events that the keyboard driver buffers. This entry is also used in calculating the size of the keyboard driver's internal buffer in nonpaged memory pool. To determine the number of bytes to allocate for the buffer, the system multiplies the size of the KEYBOARD_INPUT_DATA structure by the value of KeyboardDataQueueSize.
  • PollStatusIterations [REG_DWORD] – Specifies the maximum number of times the system verifies interrupts on the i8042 controller status register. If the interrupt cannot be verified in the number of trials specified in the value of this entry, the interrupt is ignored.
  • PollingIterations [REG_DWORD] - Specifies the maximum number of times Windows 2000 polls the hardware. If the number of trials specified in this entry is exceeded, Windows 2000 stops polling.
  • SampleRate [REG_DWORD] – Specifies how often the PS/2 driver measures the characteristics and activities of the PS/2 mouse. The driver uses the information gathered through sampling to optimize the operation of the mouse device.
  • PollingIterationsMaximum [REG_DWORD] – Specifies the maximum number of times Windows 2000 polls the hardware on older-style AT keyboards. If the number of trials specified in this entry is exceeded, Windows stops polling.
  • MouseResendStallTime [REG_DWORD] – Determines how long the mouse driver waits for an acknowledgement (ACK) of a reset if a RESEND message is returned without an ACK. This entry is used when the mouse driver interrupt service routine includes a reset.
  • OverrideKeyboardType [REG_DWORD] – Specifies the keyboard type. You can add this entry to the registry to correct an error in the keyboard type detected at startup.
  • OverrideKeyboardSubtype [REG_DWORD] – Specifies the OEM-dependent keyboard subtype. You can add this entry to the registry to correct an error in the keyboard subtype detected at startup.
