Currently the table contains two diskette types:* .iP "" 4* A <type> of 0 indicates the first entry in the table (3.5" 2HD, 1.44MB);* .iP* A <type> of 1 indicates the second entry in the table (5.25" 2HD, 1.2MB).* .LP** The <fileName> parameter is the mount point, e.g., `/fd0/'.** NOTE* Do not attempt to unmount a volume that was mounted with usrFdConfig() using * dosFsVolUnmount(). usrFdConfig() does not return the DOS_VOL_CONFIG structure * required by dosFsVolUnmount(). Instead use ioctl() with FIOUNMOUNT which* accesses the volume information via the file descriptor.** RETURNS: OK or ERROR.** SEE ALSO:* .pG "I/O System, Local File Systems, Intel i386/i486 Appendix"*/STATUS usrFdConfig    (    int     drive,	/* drive number of floppy disk (0 - 3) */    int     type,	/* type of floppy disk */    char *  fileName	/* mount point */    )    {    BLK_DEV *pBootDev;    char bootDir [BOOT_FILE_LEN];    if ((UINT)drive >= FD_MAX_DRIVES)	{	printErr ("drive is out of range (0-%d).\n", FD_MAX_DRIVES - 1);	return (ERROR);	}    /* create a block device spanning entire disk (non-distructive!) */    if ((pBootDev = fdDevCreate (drive, type, 0, 0)) == NULL)	{        printErr ("fdDevCreate failed.\n");        return (ERROR);	}    /* split off boot device from boot file */    devSplit (fileName, bootDir);    /* initialize the boot block device as a dosFs device named <bootDir> */    if (dosFsDevInit (bootDir, pBootDev, NULL) == NULL)	{        printErr ("dosFsDevInit failed.\n");        return (ERROR);	}    return (OK);    }#endif /* __INCusrFd */
