#############################################################################
NOTE:
    If you want to boot the system from a hard drive other than Hard 
    Drive C:, please don't install the Bus Master Device Drivers.

2.1 INSTALLATION
    The setup program will copy files to the directory you indicate, and
    make changes to the AUTOEXEC.BAT and CONFIG.SYS to configure the drivers.
    If the fast disk driver is installed, it will also make changes to
    SYSTEM.INI in the Windows directory.

    To run the setup program:
    1.  Change the current directory to a: or b:
    2.  Under DOS command line prompt, run the setup:
            setup <Enter>
    After entering the setup utility, just follow the instructions of the
    setup.

2.2 DE-INSTALLATION
    1.  To de-install the disk driver:
        Edit CONFIG.SYS to remark "DEVICE=C:\BMIDE\TRIDMA.SYS".
    2.  To de-install the CD-ROM driver:
        Edit CONFIG.SYS to remark "DEVICE=C:\BMIDE\TRICD.SYS ..." and also
        Edit AUTOEXEC.BAT to remark "C:\DOS\MSCDEX  /D:MSCD000".
    3.  To de-install the Fast Disk driver:
        Edit SYSTEM.INI and remark "DEVICE=C:\BMIDE\TRIINT13.386" and
        "DEVICE=C:\BMIDE\TRICTR.386",  and also set the values of
        "OverlappedIO" and "32BitDiskAccess" to OFF.  All these entries
        are under the "[386Enh]" section.
    Where the BMIDE is the directory you copied the files to.

2.3 RESTRICTIONS OF DISK DRIVER and FAST DISK DRIVER
    1.  If you want to install both of the DOS disk driver and the CD-ROM
        driver, you should setup the disk driver before the CD-ROM driver
        in the CONFIG.SYS.
    2.  The Fast Disk driver for Windows can only function if the DOS disk
        driver is loaded.

2.4 TROUBLESHOOTING
2.4.1 Overriding Drive Capabilities for the DOS Disk Driver
    If the driver does not work properly after the installation, it could
    be that the device drives report wrong capabilities. The driver provides
    parameters for the user to override the capabilities reported by the
    connected device drives.

    The user can append parameters with the following format
        [/V] [/drive [dma=dmamode|pio=piomode] [!lba] [!ms]]
    to the "device=..." statement in the CONFIG.SYS file.
    Where
    V       indicates to display verbose information, including device
            scanning progress and the chip set timing register values,
            and etc.
    drive   specifies which drive to override on.  It can be:
                PM  primary/master
                PS  primary/slave
                SM  secondary/master
                SS  secondary/slave
    dmamode specifies the overriding DMA mode. It can be:
                SW2 single word DMA mode 2
                MW1 multi-word DMA mode 1
                MW2 multi-word DMA mode 2
                U0  ultra DMA mode 0
                U1  ultra DMA mode 1
                U2  ultra DMA mode 2
                NO  not use DMA operation. The PIO will be used.
    piomode specifies the overriding PIO mode. It can be:
                0   PIO mode 0
                1   PIO mode 1
                2   PIO mode 2
                3   PIO mode 3
                4   PIO mode 4
            If the pio_mode is specified, the driver will only use PIO
            operation on the corresponding drive.
    !lba    indicates not to use LBA mode.
    !ms     indicates not to use multi-sectors commands.

    For example:
        device=c:\bmide\tridma.sys /PS dma=SW2 !lba
    indicates that we will use single word DMA mode 2 and not use LBA mode
    on the slave drive of the primary IDE channel.

2.4.2 Overriding Drive Capabilities for the CD-ROM Driver
    If the driver does not work properly after the installation, it could
    be that the CD-ROM drives report wrong capabilities. The driver provides
    parameters for the user to override the capabilities reported by the
    connected drives.

    The user can append parameters with the following format
        [/drive dma=dmamode|pio=piomode]
    to the "device=..." statement in the CONFIG.SYS file.
    Where
    drive   specifies which drive to override on.  It can be:
                PM  primary/master
                PS  primary/slave
                SM  secondary/master
                SS  secondary/slave
    dmamode specifies the overriding DMA mode. It can be:
                SW2 single word DMA mode 2
                MW1 multi-word DMA mode 1
                MW2 multi-word DMA mode 2
                U0  ultra DMA mode 0
                U1  ultra DMA mode 1
                U2  ultra DMA mode 2
                NO  not use DMA operation. The driver will use PIO on the
                corresponding CD-ROM drive.
    piomode specifies the overriding PIO mode. It can be:
                0   PIO mode 0
                1   PIO mode 1
                2   PIO mode 2
                3   PIO mode 3
                4   PIO mode 4
            If the pio_mode is specified, the driver will only use PIO
            operation on the corresponding drive.

    For example:
        device=c:\bmide\tricd.sys /SM dma=no
    indicates that we will not use DMA and only use PIO operation on the
    master drive of the secondary IDE channel.
