Routine Description:

    This routine is invoked to initialize the floppy boot device before any
    other floppy operations are attempted.  This routine performs the following
    operations to initialize the device:

        o  Clear the reset and DMA gate flags in the DOR
        o  Reset the floppy by writing the s/w reset in the DSR
        o  Set the program data rate in the CCR
        o  Issue a sense interrupt command and read the four statuses back
        o  Issue a configure command
        o  Issue a specify command

Arguments:

    None.

Return Value:
