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.


****************************************************************************

****************************************************************************
The release notes describe the current known state of the PIIX Bus Master IDE 
Driver for Windows 95*, Version 3.00 at the time of release.  The release 
notes are divided into the following sections:

    8A.  IDE Devices Supported By the Driver
    8B.  Applications Supported By the Driver
    8C.  Large (>528MB) IDE Fixed Disk Drive Support By the Driver
    8D.  Release-Specific Troubleshooting Information 
    8E.  Revision History
    8F.  Release Testing Information


****************************************************************************
* 8A.  IDE DEVICES SUPPORTED BY THE DRIVER                                 *
****************************************************************************
The Intel PIIX Bus Master IDE driver supports only specific ATA/ATAPI device 
types.  The Intel driver should not be installed if the system is equipped 
with any of the non-supported ATAPI devices.  

The Intel PIIX Bus Master IDE driver supports the following devices connected 
to the PIIX IDE interface:
    - ATA fixed disk 
    - ATAPI CD-ROM  devices

The Intel driver does not support the following types of device in the system:
    - ATAPI Tape Drives
    - ATAPI CD-ROM Changer Drives
    - ATAPI DVD-ROM Drives
    - ATAPI Writeable CD Drives
    - ATA/ATAPI ZIP*, LS-120*, Cartridge, Optical, Removable Media Drives
    - IDE Fixed Disk Drives larger than 8.4GBbytes

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

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

    Ultra DMA Mode 0    
    Ultra DMA Mode 1     
    Ultra 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 'Devices Tested'
section of this document.


****************************************************************************
* 8B.    APPLICATIONS SUPPORTED BY THE DRIVER                              *
****************************************************************************

Advanced CD-ROM applications/features have not been tested with this driver.  
This driver does not support Microsoft SMART IOCTL API and any mobile IDE 
features on portable PCs (notebooks).  If any problem is encountered, 
de-install the driver. 

The driver supports general CD-ROM operations such as: 
    - File transfers
    - Data streaming
    - Audio

The driver does not support the following applications:
    - Enhanced CD Applications such as VideoCD*, CDPlus*
    - Multi-CD changers
    - Applications used Microsoft SMART IOCTL API
    - Ontrack Disk Manager and EZ-Driver* API
    - Mobile IDE features on Notebooks


****************************************************************************
* 8C.    LARGE IDE FIXED DISK DRIVE (>528MB) SUPPORT BY THE DRIVER         *
****************************************************************************
Intel recommends that the "Auto" mode of disk recognition should be used in 
most systems' BIOS setup option when installing new disk drives.  Some older 
systems may not support the large disk drives because of BIOS limitations.  
Users are encouraged to contact their system provider for the system or BIOS 
upgrade before installing the Intel driver for large drive support.   

Intel PIIX Bus Master IDE driver for Windows 95* supports the following fixed 
disk geometry translation mechanisms. Do not install the Intel driver if the 
system does not support them or the drive is not configured to use them.
    - Standard Cylinder-Head-Sector (CHS) translation in BIOS
    - Logical Block Addressing (LBA) mode
    - BIOS Disk Services INT13h, Function 08h to report the drive geometry 
      parameters 

The Intel PIIX Bus Master IDE driver for Windows 95* does not support the 
certain disk geometry translation mechanisms.  The user should use the default 
Microsoft Windows 95* IDE driver if the system uses the following translation 
mechanisms.  
    - All other BIOS translation schemes not supported by 
      the driver.
    - Any software translation mechanisms, such as Ontrack 
      Disk Manager*, EZ-Drive*, or master boot record 
      hooking.

****************************************************************************
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 de-install 
the driver, follow the de-installation instructions outlined above in the
"DE-INSTALLING THE SOFTWARE" section.

In general, if the system fails to operate reliably, the recommendation is
to de-install the PIIX Bus Master driver. 

Q1>  Windows 95* doesn't recognize or see CD-ROM drive on the secondary IDE 
     interface after system is restarted.

A1>  Some ATAPI CD-ROM drives  may need to be placed on the same cable, as a 
     slave, to a Hard Disk drive, which is configured as a Master.  Below is  
     a list of  some CD-ROM drives that meet this requirement.  Generally, 
     with the exception of  the devices listed below,  the recommended 
     configuration for a single ATAPI CD-ROM drive on a cable is as a Master.

            Mitsumi* FX400       NEC* CDR251      Toshiba* XM5302B
            Sony*    CDU55E      NEC* CDR261      Toshiba* XM5602B
            Sony*    CDU76E      NEC* CDR271
            Torisan* CDR-C3G     NEC* CDR272
            Torisan* CDR-S1G     NEC* CDR273

Q2>  There is an Exclamation(!) or Question(?) mark next to the primary or 
     secondary IDE controller instance under Device Manager where devices are 
     connected.   -OR-

     The secondary IDE controller instance is missing under 
     Device Manager and devices are connected to this cable.

A2>  There are several possible causes for this issue: 
       1.  Your CD-ROM drive may need be configurated as a slave drive.  
           Please refer to Item A1 for a detailed description. 
          
       2.  There is a hardware conflict in the system. Only TWO IDE 
           channels are allowed in a system. The driver will not operate on 
           systems that have a non-Intel IDE controller or a sound card with 
           an IDE interface.  The driver should not be de-installed on these 
           systems.

       3.  The system BIOS may not have initialized the 82371xB IDE controller 
           properly.  Again, please contact your system provider for BIOS 
           upgrade.

     If the system fails to operate reliably, de-install the driver.


Q3>  The system does not operate reliably  or fails to boot when the driver 
     is installed.  
     -OR-
     The system fails to boot in  NORMAL (non SAFE-MODE) mode when the driver 
     is installed.     

A3>  Please de-install the driver.  Please make sure that your system meets 
     the system requirements of the driver and you don't have any non-
     supported IDE devices or applications installed on the system.  

     Please refer to the Release Notes section for supported devices and 
     applications.    


Q4>  One or more of the IDE/ATAPI drives on the system fail to perform 
     correctly and/or is not recognized by the driver.

A4>  Ensure devices on the system are connected according to the 
     manufacturers' documentation.  Please make sure that you don't have any 
     non-supported IDE devices or applications installed on the system.  
     Please refer to the release note for supported devices and applications.

     If the system fails to operate reliably, de-install the driver.


Q5>  The CD-ROM drive fails to perform correctly  after the driver has been 
     installed (e.g. audio CD-ROMs or some advanced CD-ROM applications don't 
     operate correctly).

A5>  Please ensure that ONLY supported IDE devices or applications are 
     installed on the system.  Please refer to the release note for supported 
     devices and applications. 
  
     A conflict between the PIIX Bus Master IDE driver and a DOS 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 there is NO real-mode driver for the device is 
     installed, de-install the driver.

     If the system fails to operate reliably, de-install the driver.


Q6>  The driver does not support the following CD-ROM drives.  
        Gallant GCD-R542B
        Mitsumi FX400
        Torisan S1G
        Torisan C3G
        Toshiba XM-5302B
        Wearnes CDD-220
        Wearnes CDD-620
        Wearnes CDD-820
                               
A6>  Do not install the driver on a system equipped with these CD-ROM drives.  
     There are no plans to support these drives with the PIIX Bus Master 
     driver.


Q7>  The driver does not support  the following fixed disk drives:
        Conner CFA850A
        Maxtor 71626A
        Maxtor 71260AT
                
A7>  Do not install the driver on a system equipped with these fixed disk 
     drives.  There are no plans to support these drives with the PIIX Bus 
     Master driver.


Q8>  Windows 95 fails to report the actual size of the drive.
     -OR-
     Data loss or system hang has occurred after installing the PIIX Bus Master 
     driver.

A8>  If your disk drive is > 528MB, you should check and compare the capacity 
     of the drive before and after installing PIIX Bus Master IDE driver. 

     If the system fails to operate reliably, de-install the driver.

     It is recommended to de-install the system in 
     Safe mode:  Press the "F8" function key when you see "Starting Windows 
     95";  Select "Safe mode"; and de-install the Intel driver after the 
     system has re-booted.   


Q9>  How can I play MS-DOS based CD-ROM games?  -OR-
     I could not access my CD-ROM drive in MS-DOS real mode.

A9>  Your CD-ROM drive is not available in MS-DOS mode because CD-ROM 
     real-mode driver is not loaded.  There is a conflict between Intel PIIX 
     Bus Master IDE driver and a DOS real-mode ATAPI CD-ROM device driver. 
     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. 

     To workaround the issue, you can create a custom startup configuration 
     that loads CD-ROM real-mode driver. The game will run in exclusive 
     MS-DOS mode using its own MS-DOS configuration.

     To Create a Exclusive MS-DOS Mode For MS-DOS CD-ROM Games:
     1.  Right-click the game's executable file in My Computer
     2.  Click on Properties
     3.  Click on Advanced...
     4.  In the Advanced dialog box, click on MS-DOS mode
     5.  Select "Specify a new MS-DOS configuration" to edit
         the CONFIG.SYS and AUTOEXEC.BAT files.
     6.  Please refer to your CD-ROM manual for the proper 
         command line settings of CD-ROM real-mode driver and
         MSCDEX.EXE in CONFIG.SYS and AUTOEXEC.BAT files.
     7.  Please refer to game manual for the required system 
         environment settings. 
        
        *** Sample CONFIG.SYS File ***
        DOS=HIGH,UMB
        DEVICE=C:\WINDOWS\HIMEM.SYS
        DEVICE=C:\nec_ide.sys /D:MSCD000


        *** Sample AUTOEXEC.BAT ***
