NOTE:
    This version of driver doesn't support PIIX4 (TX) motherboards!

1   INSTALLATION
    1.  Copy TRIOS2.ADD from the floppy diskette to your hard disk under
        the OS2 directory (i.e., C:\OS2).
    2.  Edit C:\CONFIG.SYS  to  replace
            BASEDEV=IBM1S506.ADD
            with
            BASEDEV=TRIOS2.ADD
    3.  Reboot the system.

2   DE-INSTALLATION
    1.  Edit C:\CONFIG.SYS  and change
            BASEDEV=TRIOS2.ADD
            back to
            BASEDEV=IBM1S506.ADD
    2.  Reboot the system.

3   TROUBLESHOOTING
3.1 Overriding Drive Capabilities
    If the OS/2 system does not work properly after the installation,
    it could be that the device drives report wrong capabilities. The user
    can use parameters 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 "BASEDEV=TRIOS2.ADD"
    Where
    V       indicates to display verbose information.
    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
                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.
