    controller instance (the instance that does not have Primary or Secondary 
    in the text).

    If only one of the Primary or Secondary instances is present, there 
    should be no yellow warning symbol next to it.

    If both Primary and Secondary instances are present, there should be no 
    yellow marks next to the controller instances where devices are connected.

    NOTE:   It is NORMAL for a yellow warning symbol to be displayed next to
            either the Primary or Secondary interface when there is no device
            connected to it.

    If a yellow warning symbol appears in error, the driver may not have been
    installed and/or may not be working properly.

7.  Verify proper controller operation when the driver is installed (CASE 3). 

    If only one instance is present, there should be no yellow warning symbol 
    next to it.

    If both instances are present, there should be no yellow marks next to
    the instances where devices are connected.

    NOTE:   It is NORMAL for a yellow warning symbol to be displayed next to
            a controller instance when there is no device connected to it.

    If a yellow warning symbol appears in error, the driver may not be
    installed and/or working properly.

****************************************************************************
*       UN-INSTALLING THE SOFTWARE - MANUAL METHOD                         *
****************************************************************************
This procedure allows one to un-install the PIIX Bus Master IDE driver, and
restore the default Windows 95 driver for IDE support.

This un-install procedure is specific only to the version of the driver
and installation file included with this package.  Depending on the
configuration of the system, subsequent re-installations of the driver may
require an entirely new installation of the Windows 95 operating system.

NOTE:      Record the locations of the driver installation and Windows 95 
        directories before un-installing the driver.

1.  Close any running applications.

2.  Un-install the PIIX Bus Master IDE driver.

    A.  Delete the associated .INF file.

        1.) Go to the INF directory.
            a.  Invoke the MS-DOS* Prompt applet.
            b.  Type: 
                    cd <Windows 95 directory>\INF

        2.) Determine which .INF file to delete.  The *.INF file for
            the PIIX Bus Master IDE driver is located in one of the
            files named either:
            IDEATAPI.INF (if the auto-install method was followed) 
            -OR-
            OEM<x>.INF (if the manual method was followed).  

            In the OEM<x>.INF case, There may be one or more of these 
            OEM<x>.INF files loaded on the system.  To determine the correct 
            one to delete, perform a file compare between each of the 
            OEM<x>.INF files and the IDEATAPI.INF file located in the driver 
            install directory.  Other devices may have an OEM<x>.INF file 
            associated with them, so it is important to select the correct 
            one.
            Another way to determine the correct OEM<x>.INF file to delete is 
            to use the FIND command.  Change to the INF directory and locate 
            all OEM<x>.INF (oem0.inf, oem1.inf, etc.) files. PIIX_HDC is a 
            unique pattern contained in the drivers inf file.

            For example,to determine if OEM0.INF is the correct INF file, 
            type:

                find /I "PIIX_HDC" oem0.inf
            
            If oem0.inf is the correct file then this message will be printed:

                "-------OEM<x>.INF
                %INTEL%=PIIX_HDC
                [PIIX_HDC]"
            
            If this is not the case, repeat for each OEM<x>.INF file in the
            INF directory.

        3.) Delete the correct driver INF file.

    B.  Delete the associated driver file.

        1.) Go to the IOSUBSYS directory.
            a.  Invoke the MS-DOS Prompt applet.
            b.  Type:
                    cd <Windows 95 directory>\SYSTEM\IOSUBSYS

        2.) Delete the driver binary file:
                del IDEATAPI.MPD

    C.  Open the Control Panel folder.

    D.  Invoke the System applet.

    E.  Click on the Device Manager tab.

    F.  Select the View Devices by Type option.  A list of the devices
        connected to the system will be displayed.

    G.  Click on the Hard Disk Controllers record.  There could be three
        cases.

        For CASE 1, there could be up to three instances listed:
        Intel 82371SB PCI Bus Master IDE Controllers
        Primary Bus Master IDE Controller
        Secondary Bus Master IDE Controller
        Go to step H for CASE 1.

        For CASE 2, there could be up to three instances listed:
        Intel 82371FB PCI Bus Master IDE Controllers
        Primary Bus Master IDE Controller
        Secondary Bus Master IDE Controller
        Go to step H for CASE 2.

        For CASE 3, there could be up to two instances listed:
        Intel PIIX PCI Bus Master IDE Controller
        Intel PIIX PCI Bus Master IDE Controller
        Go to step I for CASE 3.

        NOTE FOR ALL CASES:
        a.  The content of the text strings is dependent on the driver's INF 
            file (named IDEATAPI.INF in the driver's install directory).  
            As a result, the individual controller descriptions may vary
            slightly from what is listed above.  In this case, select
            the closest match.

        NOTES FOR CASES 1 and 2:  
        b.  Depending on the current system configuration, only one of the 
            instances displayed for the Primary or Secondary IDE controllers 
            may be displayed.
        c.  The order in which the individual hard disk controller instances 
            are listed may vary.

        NOTE FOR CASE 3:

*       TROUBLESHOOTING                                                    *
****************************************************************************
The following procedure assumes that the hardware/software requirements from
above have been satisfied.  The following procedure also assumes that the
installation of the driver was performed as described in the 'Verifying 
Installation of the Driver' section.  Refer to the 'Release Notes' section
of the document for additional information.

COMMON PROBLEMS:
****************

1.  The device is incompatible with PCI Bus Master IDE operation.
    This is due to the fact that the device does not work properly when
    accessed in a PCI Bus Master IDE fashion.  Contact the device
    manufacturer for more information.

2.  Verify the length of the cables that are being used to connect the IDE or
    ATAPI devices to the primary and secondary PIIX IDE interfaces.  The
    length of these cables from END-TO-END should not exceed 18 inches
    (0.46 m).  Furthermore, the capacitance of the cable should not exceed
    35 pF.

3.  A conflict between the PIIX Bus Master IDE driver and a real-mode ATAPI
    CD-ROM or IDE device driver may occur if the real-mode driver references
    have not been properly removed from the AUTOEXEC.BAT and/or CONFIG.SYS
    files.  This conflict occurs when the PIIX Bus Master IDE driver attempts
    to access the legacy ISA IDE resources to control the PIIX.  
    ALL REFERENCES TO REAL-MODE DRIVERS (IDE or ATAPI) IN THE AUTOEXEC.BAT 
    AND CONFIG.SYS MUST BE REMOVED.


****************************************************************************
*       IDENTIFYING THE SOFTWARE VERSION NUMBER                            *
****************************************************************************
The driver's version can be determined by using one or more of the following
procedures.

PROCEDURE 1:  Reading Windows* properties embedded in the driver file while 
the driver is installed.  
When the driver is installed, the driver version  can be obtained through
the Control Panel->System applet.  This procedure is described in the 
'Verifying Installation of the Driver' section.
 
PROCEDURE 2:  Reading Windows* properties embedded in the driver file when 
the driver is not installed.
When the driver is not installed, the driver version can be obtained by
querying the driver file's properties under My Computer.

    1.  Invoke the My Computer applet.

    2.  Select the path containing the driver file.

    3.  Select the driver file, IDEATAPI.MPD.

    4.  Open the File menu.

    5.  Click on the Properties item.

    6.  Click on the Version tab.

    7.  The driver's version should be listed in the 'Product Version' 
        portion of the dialog.

PROCEDURE 3:  Using the SEEVER.EXE utility when Windows* properties are not 
embedded in the driver file.
If procedures 1 or 2 failed to describe the version of the driver, the 
SEEVER.EXE utility may be used to determine the current driver version.

The following procedure uses the SEEVER.EXE utility to identify the version
number and build date of the PIIX Bus Master IDE driver.  This procedure
assumes that the SEEVER.EXE utility and the driver file (IDEATAPI.MPD) are 
in the same working directory.

    1.  Open an MS-DOS command window.

    2.  Go to the directory where the driver is installed:
        Type
            cd <Windows 95 directory>\System\IOSubSys

    3.  Run the version identification utility (SEEVER.EXE):
        Type 
            <driver installation drive & directory>\SEEVER IDEATAPI.MPD

            Assumes that SEEVER.EXE is located in the driver's 
            installation directory.

****************************************************************************
*       STORAGE DEVICES SUPPORTED BY THE DRIVER                            *
****************************************************************************
The driver supports only ATA fixed disk and ATAPI CD-ROM devices connected 
to the PIIX IDE interface.  The driver does not support ATAPI tape drives.

During initialization, the driver will auto-identify all the devices 
connected to the PIIX IDE interface.  Depending on the capabilities of the 
devices connected to the system, the driver will initialize the PIIX IDE 
interface for bus mastering operation.

Only ATA fixed disk and ATAPI CD-ROM devices identified as bus master 
capable will be accessed as a bus master;  all other ATA fixed disk and 
ATAPI CD-ROM devices will be accessed in a PIO-only fashion.  In general, 
bus mastering is possible for ATA fixed disk and ATAPI CD-ROM devices that 
support the following DMA timing modes:

    Single Word DMA Mode 2
    Multi-Word DMA Mode 1
    Multi-Word DMA Mode 2

These devices will be accessed by the driver in either a bus mastering or a
PIO-fashion, depending on the specific transfer conditions.

Devices that do not support the DMA timing modes listed above, or whose PIO 
timings are faster than their DMA timings, will be accessed in a PIO-fashion 
ONLY.

For more information and a list of tested devices, see the RELEASE NOTES
section of this document.

*       RELEASE NOTE OVERVIEW                                              *
****************************************************************************
The release notes describe the current, known state of the PIIX Bus Master 
IDE Driver for Windows 95.  The release notes are divided into 
three sections:

        General Release Information
        Release-Specific Troubleshooting Information
        Release Testing Information

****************************************************************************
*       GENERAL RELEASE INFORMATION                                        *
****************************************************************************

The driver supports general CD-ROM operations such as: file transfers, data
streaming and audio.  Advanced CD-ROM applications/features (VideoCD*, CDPlus*, 
multi-CD changers, etc), especially those outside of the scope of the
current Windows 95 CD-ROM support, have not been tested with this driver.  
If a problem is encountered, un-install the driver.

Since the driver does not support ATAPI tape drives, this release of the 
driver should not be installed on systems with ATAPI tape drives.  If the 
driver has been installed on a system with an ATAPI tape drive and problems 
are experienced, un-install the driver.


****************************************************************************
*       RELEASE-SPECIFIC TROUBLESHOOTING INFORMATION                       *
****************************************************************************
Verifying the installation of the driver and other generic troubleshooting 
is discussed in the "TROUBLESHOOTING" section above.  This section describes
release-specific troubleshooting.

This section contains a list of known problems with certain system
configurations discovered during testing of the driver.  A list of all
storage devices tested with the driver is given below in the "RELEASE
TESTING INFORMATION" section of this document.
 
If the solution given to any of the problems listed below is to un-install 
the driver, follow the un-installation instructions outlined above in the
section "UN-INSTALLING THE SOFTWARE".

    Issue:      The system does not operate reliably or fails to boot when 
                the driver is installed. 
 
    Solution:   Un-install the driver.
                                

    Issue:      The system fails to boot in NORMAL (non-SAFE-MODE) mode when
                the driver is installed.

    Solution:   Un-install the driver.


    Issue:      One or more of the IDE/ATAPI drives on the system fail to
                perform correctly and/or is not recognized by the driver.

    Solution:   Ensure that devices on the system are connected according to 
                the manufacturers' documentation.  
                
                If the system still fails to operate reliably, Un-install 
                the driver.


    Issue:      The CD-ROM drive fails to perform correctly after the driver
                has been installed (e.g. audio CD-ROMs or advanced CD-ROM
                applications fail to perform correctly).

    Solution:   A conflict between the PIIX Bus Master IDE driver and a 
                real-mode ATAPI CD-ROM device driver may have occurred.  This 
                conflict occurs when both the real-mode driver and the PIIX 
                Bus Master IDE driver attempt to access the resources of the 
                PIIX controller.  

                If the drive fails to operate in the case that NO real-mode
                driver for the device is installed, Un-install the driver.


    Issue:      The driver is not compatible with EZ-Drive* floppy boot
                protection option. 
 
    Solution:   If EZ-Drive is installed on the boot drive, the floppy boot
                protection option must be disabled prior to installing the
                PIIX Bus Master IDE Driver for Windows 95.  If, for any 
                reason, the floppy boot protection cannot be disabled, the 
                driver should not be installed.                              


    Issue:      The driver does not support CD-ROM audio playback with the
                following CD-ROM drives:

                    Gallant GCD-R542B
                    Mitsumi FX400
                    Torisan S1G
                    Torisan C3G
                    Toshiba XM-5302B
                    Wearnes CDD-220

    Solution:   Do not install the driver in configurations equipped with
                these CD-ROM drives.


    Issue:      The driver does not support the following fixed disk drives:

                    Conner CFA850A
                    Maxtor 71626A
                    Maxtor 71260AT
                
    Solution:   Do not install the driver in configurations equipped with
                these fixed disk drives.
