1.  Now works with Stealth mode in QEMM.

2.  Can now disable 32 Bit Disk Access using Windows (WIN /D:X) command line
    option.

    future hard disk device drivers.

4.  Changed text in error messages to be more descriptive of the event.

5.  Resolved issues in which segment load failures, general protection
    faults and reduced performance were being seen in some specific
    host environments.

    DMA data transfers will not be enabled in systems that do not properly
    implement DMA.

    sign on message when switch is enabled.

    drive/controller capabilities such as 32 Bit PIO transfers, DMA, etc..
    can be supported.

10. Now supports 32 Bit PIO data transfers if the Phoenix EDD indicates
    host support for this feature.

11. Added an OEM mode which incorporates unique features for specific system
    vendors.
