                    Bus Master EIDE/ATAPI Device Driver
                          for Intel Triton Chipset
                              Version 1.00E
                             (August 7, 1995)


  Overview

    The Triton Bus Master EIDE/ATAPI Device Drivers created by
    TRIONES Technologies, Inc. has the following features:

    1)  Takes advantage of the Triton chipset bus mastering capability and
        support bus mastering IDE on both IDE hard disks and ATAPI CD-ROM
        drives. This greatly reduces the CPU utilization and increases the
        data transfer rate.
    2)  Supports advanced data transfer timing modes. The PIO mode can be up
        to mode 4, and the DMA mode can be up to multiple word mode 2.
    3)  Supports LBA mode and Multiple-Block (or Multiple-Sector) commands.

    This readme will describe the setup procedures for the Triton Bus Master
    Device Driver for each operating system. The Triton Bus Master Device
    Drivers can only be used on motherboards with the Triton chipset and the
    system BIOS must properly initialize the Triton chipset IDE interface
    for the Bus Master IDE operation. Do not use any other add-in IDE (PCI
    or ISA) card in the system.

  INSTALLATION

    1)  Close any running applications.
 
    2)  Remove references to installed real-mode, IDE device drivers in the
        AUTOEXEC.BAT and CONFIG.SYS files, especially any drivers that 
        control ATAPI CD-ROM and special IDE features.

    3)  Remove references to the default installed IDE device drivers.
        A.  Open the Control Panel folder.
    
        B.  Invoke the System applet.
    
        C.  Click on the Device Manager option.
    
        D.  Click on the View Devices by Type button.
            A list of the system devices connected to the system 
            will be displayed.
    
        E.  Click on the Hard disk controllers record. There could be two 
            cases.  
            For case 1, there should be three instances listed:
            * Intel PIIX PCI IDE Controller (Bus Mastering not supported)
            * Primary IDE controller (dual FIFO) 
            * Secondary IDE controller (dual FIFO)
            Goto step F for case 1.
    
            For case 2, there should be two instances listed:
            * Standard ESDI/IDE Controller
            * Standard ESDI/IDE Controller
            Goto G for case 2.
    
        F.  Remove the Intel PIIX PCI IDE Controller's listing (case 1).
            1.  Select the Intel PIIX PCI IDE Controller.
            2.  Click on the Remove option.
            3.  Select OK when prompted to remove this controller.
            4.  Goto step H.
    
        G.  Remove the Standard ESDI/IDE Controller listings (case 2).
            1.  Remove the Secondary Controller's listing.
            a.  Select the Second instance of the Standard ESDI/IDE 
                Controller.
            b.  Click on the Remove option.
            c.  Select Yes when prompted to remove this controller.
    
            2.  Remove the Primary Controller's listing.
            a.  Select the remaining instance of the Standard ESDI/IDE 
                Controller.
            b.  Click on the Remove option.
            c.  Select Yes when prompted to remove this controller.
    
        H.  Select Yes when prompted to re-start Windows 95*.
        I.  Windows 95* will re-start.
     
    4)  Install the Bus Master EIDE/ATAPI driver when prompted to do so.
        A.  Windows 95* will report that an Intel PIIX PCI IDE Controller 
            or a Standard ESDI/IDE Controller has been detected in the 
            system. Select Driver from disk provided by hardware manufacturer.
    
        B.  Insert the floppy disk containing the driver file (IDEATAPI.MPD) 
            and installation file (IDEATAPI.INF) into the system.
    
        C.  Type in \WIN95 and choose OK to load the driver from the A:\WIN95
    
        D.  Windows 95* will display a Select Device window. Choose OK.
            Note:
            *  If Windows 95* reported that an Intel PIIX PCI IDE Controller
            has been detected, the selected device type should be the
            Intel Triton Bus Master IDE Controllers.
            *  If Windows 95* reported that a Standard ESDI/IDE Controller
            has been detected, the selected device type should be the
            Intel Triton Bus Master IDE Controller.
    
        E.  When prompted to re-insert the floppy containing the 
            IDEATAPI.MPD file, choose OK again.
            Note:
            *  Windows 95* may not be able to process the .INF file and .MPD
            file the first time, choose OK again if this happens.
    
        F.  Select Yes when prompted to re-start Windows 95*.
    
        G.  Windows 95* will report that the system settings have changed.
            Select Yes when prompted to re-start Windows 95*.
     
    The IDEATAPI.MPD driver will be installed and used as long as the 
    Triton IDE interface is enabled. After installation, the IDEATAPI.MPD 
    file is stored in the c:\<Windows 95* directory>\System\IOSubSys 
    directory.  
    
    The IDEATAPI.INF information on the install floppy is integrated into 
    the    Windows 95* device database for automatic support of the Intel 
    Triton Bus Master IDE Controller and is stored in the 
    c:\<Windows 95* directory>\INF directory as one of the files named 
    OEM<x>.INF (name varies depending on system.)
        
4.2 DE-INSTALLATION

    This procedure allows one to de-install the use of the Intel
    Triton Bus Master EIDE/ATAPI device driver and restore the default
    Windows 95* device driver for IDE support.

    1)  Close any running applications.

    2)  Un-install the bus master driver.
        A.  Open the Control Panel folder.
    
        B.  Invoke the System applet.
    
        C.  Click on the Device Manager option.
    
        D.  Click on the View Devices by Type option.
            A list of the system devices connected to the system
            will be displayed.
    
        E.  Click on the Hard disk controllers record.
            For case 1, there should be three instances listed.
            *  Intel Triton Bus Master IDE Controllers
            *  Primary IDE controller
            *  Secondary IDE controller
            Goto step F for case 1.
    
            For case 2, there should be two instances listed:
            * Intel Triton Bus Master IDE Controller
            * Intel Triton Bus Master IDE Controller
            Goto step G for case 2.
    
        F.  Remove the Intel Triton Bus Master IDE Controllers
            listings (case 1).
            1.  Select the Intel Triton Bus Master IDE Controllers listing.
            2.  Click on the Remove option.
            3.  Select OK when prompted to remove this controller.
            4.  Goto step H.
    
        G.  Remove the Intel Triton Bus Master IDE Controller 
            listings (case 2).
            1.  Delete the associated .INF file:
            a.  Go to the .INF directory:
                (1) Invoke the MS-DOS* Command prompt
                (2)     cd c:<Windows 95* directory>\INF
            b.  Determine which INF file to delete. The Intel Triton Bus
                Master IDE Controller .INF file is located at one of the 
                files named OEM<x>.INF. There may be one or more of these 
                OEM<x>.INF files loaded on the system. To determine the 
                correct one to delete use file compare to compare each of 
                the OEM<x>.INF files to the    IDEATAPI.INF file on the install
                floppy. Other devices may be stored as an OEM*.INF file, so 
                it is important to select the correct one.
            c.  Delete the correct OEM<x>.INF file. 
    
            2.  Remove the Secondary Controller's listing.
            a.  Select the Second instance of the 
                Intel Triton Bus Master IDE Controller.
            b.  Click on the Remove option.
            c.  Select Yes when prompted to remove this controller.
    
            3.  Remove the Primary Controller's listing.
            a.  Select the remaining instance of the 
                Intel Triton Bus Master IDE Controller
            b.  Click on the Remove option.
            c.  Select Yes when prompted to remove this controller.
    
        H.  Select Yes when prompted to re-start Windows 95*
        
        I.  Windows 95* will restart.
    
    3.  Install the default Windows drivers when prompted to do so.
        A.  Windows 95* will report that the Intel PIIX PCI IDE Controller
            (Bus mastering not supported) has been detected. Select the 
            Windows default driver for installation.
    
        B.  Select Yes when prompted to re-start Windows 95*
