                    Bus Master EIDE/ATAPI Device Driver
                 for Intel PIIX Bus Master IDE Controller

                              Revision 3.70
                            (October 10, 1997)


1.  Some ATAPI CD-ROM drives need different workarounds. These workarounds
    were added into the drivers. Now more ATAPI CD-ROM models are supported.
    The following CD-ROM drives were fully tested:
        MITSUMI FX400,FX400B,FX400C,FX400D
        SONY CDU55E,CDU76E,CDU77E,CDU78E
        HITACHI CDR-7730
        NEC CDR260R,CDR271,CDR272,CDR273
        TOSHIBA XM-5302B
        WEARNES CDD-120A,CDD-220,
        OAK EVALUATION
        PHILIPS LMS CM207
    (version 3.0)

2.  New workaround about WD Caviar hard disk drives recommended by Western 
    Digital was used.
    (version 3.0)

3.  In Windows 95 system, when entering the DOS mode, the original PIIX 
    configuration and drive configuration will be restored. There will be
    no more error message or garbage characters when exiting into the 
    DOS mode.
    (version 3.0)

4.  The driver for Windows 95 now allows a maximum 64K data transfer size
    for one command. The performance is much better than before.
    (version 3.0)

5.  For the previous versions, if a Windows 95 system was installed 
    without the DOS or Windows 3.1 pre-installed, for the following 
    device combination:
            0x1F0:  a DMA supported disk drive
            0x170:  a PIO only CD-ROM drive
    accesssing the CD-ROM sometimes would result in an "Exception 0E ..."
    error message.
    This issue now is fixed.
    (version 3.0)

6.  The bus master IDE is a new technology. With so many IDE/ATAPI devices
    already in the market, there are a lot of compatability issues. Our bus 
    master IDE/ATAPI device drivers are the first ones in the market. We 
    have been keeping in touch with the IDE hard disk and ATAPI CD-ROM device
    manfacturers. Since the last release (version 3.0), we have gotten some 
    new feedbacks from them. We adjusted the default mode settings for some 
    hard disks into the drivers.
    (version 3.1)

7.  The following new CD-ROM models were tested:
        WEARNES CDD-620
        SANYO CRD-254P

8.  We provided a new method to change back to the Windows 95 default
    driver, please refer to the readme file.
    (version 3.1)

    wrong PIO mode. This problem was fixed in this release.
