* 2.  INSTALLING THE SOFTWARE                                              *
****************************************************************************

NOTE:   This procedure assumes that the software device driver (PIIXIDE.SYS),
        installation file (PIIXIDE.INF) and tag file (DISK1.NT) are located
        in the same directory.  Record the locations of the driver
        installation and Windows NT directories before installing the
        driver.  Although the driver is installed as a SCSI device driver,
        the driver only works for devices connected to the IDE channels.

1.  Check the System Requirements.  Windows NT and Service Pack 3 must be 
    fully installed and running on the system prior to installing the 
    driver.

2.  Close all running applications.

3.  Run SETUP.EXE, located in the same directory as this README.TXT file.

4.  You will be prompted to agree to the licensing agreement.  If you do not
    agree, the Installer will exit prior to extracting the necessary driver
    files.

5.  When prompted, choose the location in which to place the PIIX Bus
    Master IDE files.  The default location is C:\PIIXIDE - modify this
    location if desired.

6.  When prompted, choose whether to view the README.TXT file.

7.  At this point, the automated PIIX Bus Master IDE installer is complete.
    Manual installation is now required to complete driver installation.

8.  Select START/SETTINGS/CONTROL PANEL.

9.  Invoke the "SCSI Adapters" applet.

10.  Click on the folder tab labeled "Drivers."  The currently installed
     SCSI adapter drivers will be listed in the Drivers menu.    

     The display MAY list the default driver, 
     "IDE CD-ROM (Atapi 1.2) / Dual-Channel PCI IDE Controller"
     OR a previous install of the PIIX Bus Master IDE driver, 
     "Intel PIIX PCI Bus Master IDE Controller".

     NOTE:  this text may vary according to the release of Windows* NT 4.0.  

     If NONE of these adapter drivers is listed, go to Step 13 below.

11.  If the "Intel PIIX PCI Bus Master IDE Controller" driver is listed, 
     select it.  Then, select "Remove" to remove the driver.

12.  If the default driver ("IDE CD-ROM (Atapi 1.2) / Dual-Channel PCI IDE") 
     is listed, select it.  Then, select "Remove" to remove the driver.

13.  Select "Add..." to add a new driver.

14.  From the "Install Disk" dialog box, select "Have Disk".
             
15.  The "Windows NT Setup" dialog box will appear prompting for the path of
     the installation files.   Specify the location of the driver 
     installation directory when prompted to do so.  

16.  Click on "Intel PIIX PCI Bus Master IDE Controller" driver and then
     click "Ok".

     NOTE:  If the driver was previously installed on the system, a dialog
            box will appear that states that driver for the "Intel PIIX PCI
            Bus Master IDE Controller" is already on the system.  If this
            occurs, select "New" to install the new driver.

17.  When prompted, reboot the system as directed in order for the changes to 
     take effect.


     NOTE:  After installation, the PIIXIDE.SYS file is stored in the
            <Windows NT directory>\System32\Drivers directory.

****************************************************************************
The "PIIX Bus Master IDE Driver for Microsoft Windows* NT version 4.0"
package contains the following items:

1.  PIIX Bus Master IDE Driver:
        PIIXIDE.SYS

2.  Installation File:

3.  Readme File:
        README.TXT

4.  Driver Tag File:
        DISK1.NT

****************************************************************************
* 7.  DEVICE CONFIGURATION INFORMATION                                     *
****************************************************************************

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 via
Direct Memory Access (DMA modes); 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 via either DMA or PIO accesses,
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 Testing'
section of this document.

* 8.  RELEASE NOTES                                                        *
****************************************************************************
These release notes describe the current, known state of the PIIX Bus Master 
IDE Driver version 2.04.0 for Windows NT* version 4.0.  The release notes
are divided into two sections:

	  8a.  Release-Specific Troubleshooting Information
	  8b.  Changes Included from Previous Release

****************************************************************************
* 8a.  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 discovered via testing
the driver under certain system configuration.  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 section "DE-INSTALLING
THE SOFTWARE".

    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, De-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:   De-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 NT.  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 changer drives.

    Solution:   Do not install the driver in configurations equipped with
                this type of device.


****************************************************************************
* 8b.  CHANGES INCLUDED FROM PREVIOUS RELEASE                              *
****************************************************************************

o Added support for CD-R and CD-RW device classes.

o Added support for UDMA CD-ROM devices

o Implemented a command parser for all ATA/ATAPI commands from ASPI, to
counteract a condition in which the data flow direction was indeterminate.

o Implemented a feature to flush hard disk drive write cache at system
shutdown, to prevent data loss in the case the hard disk drive
experiences power loss before its write cache has been written to disk.

o Configure all ATAPI tape drives for their fastest possible PIO mode;
the Intel PIIX Bus Master IDE driver no longer configures this device
class for DMA transfers.

o With the Windows NT4 crashdump feature enabled, in the case of a system
crash, the driver can now successfully write the dump log to the hard
disk drive.
