Linux fstab file

I have tried to create a mount point in which i can view the files on my Secondary Hard Drive Master. I made the mistake at trying to guess the fs type bad bad bad... anyways now my linux does not boot up but it does give me the option to enter root password and then i can edit my fstab file. Here is my problem. The only Editor I can use is VI and I don't know how to save and exit after I delete the line I need to in the fstab file. So can anyone
a) tell me how to correctly delete the line in VI
b) Save the file after i delete the line in VI
c) by chance know the correct file type for WIN95

I would not ask all these question but I had put my books in storage and do not have any resources on hand.
TIA

The file fstab contains descriptive information about the various file systems.  fstab is only read by programs, and not written;
Each filesystem is described on a separate line; fields on each line areseparated by tabs or spaces.  The order of records in fstab is important because fsck(, mount(, and umount( sequentially iterate through fstab doing their thing.

The first field, (fs_spec), describes the block special device or remote filesystem to be mounted.      For filesystems of type ufs, the special file
    name is the block special file name, and not the character special file name.  If a program needs the character special file name, the program must create it by appending a ``r'' after the last ``/'' in the special file name.

The second field, (fs_file), describes the mount point for the filesys­ tem.  For swap partitions, this field should be specified as ``none''.

The third field, (fs_vfstype), describes the type of the filesystem.  The system can support various filesystem types.  Only the root, /usr, and
    /tmp filesystems need be statically compiled into the kernel; everything
    else will be automatically loaded at mount time.  (Exception: the UFS
    family - FFS, MFS, and LFS cannot currently be demand-loaded.)  Some peo­ple still prefer to statically compile other filesystems as well.

        ufs         a local UNIX filesystem

        mfs         a local memory-based UNIX filesystem

        nfs         a Sun Microsystems compatible ``Network File System''

        swap    a disk partition to be used for swapping

        msdos   a DOS compatible filesystem

        cd9660  a CD-ROM filesystem (as per ISO 9660)

        procfs  a file system for accessing process data

        kernfs  a file system for accessing kernel parameter

    The fourth field, (fs_mntops), describes the mount options associated
    with the filesystem.  It is formatted as a comma separated list of
    options.  It contains at least the type of mount (see fs_type below) plus
    any additional options appropriate to the filesystem type.  See the
    options flag (-o) in the mount( page and the filesystem specific page,
    such as mount_nfs(, for additional options that may be specified.

    If the options ``userquota'' and/or ``groupquota'' are specified, the
    filesystem is automatically processed by the quotacheck( command, and
    user and/or group disk quotas are enabled with quotaon(.  By default,
    filesystem quotas are maintained in files named quota.user and
    quota.group which are located at the root of the associated filesystem.
    These defaults may be overridden by putting an equal sign and an alterna­
    tive absolute pathname following the quota option.  Thus, if the user
    quota file for /tmp is stored in /var/quotas/tmp.user, this location can
    be specified as:

        userquota=/var/quotas/tmp.user

    If the option ``noauto'' is specified, the filesystem will not be auto­
    matically mounted at system startup.

    The type of the mount is extracted from the fs_mntops field and stored
    separately in the fs_type field (it is not deleted from the fs_mntops
    field).  If fs_type is ``rw'' or ``ro'' then the filesystem whose name is
    given in the fs_file field is normally mounted read-write or read-only on
    the specified special file.  If fs_type is ``sw'' then the special file
    is made available as a piece of swap space by the swapon( command at
    the end of the system reboot procedure.  The fields other than fs_spec
    and fs_type are unused.  If fs_type is specified as ``xx'' the entry is ignored.  This is useful to show disk partitions which are currently unused.

    The fifth field, (fs_freq), is used for these filesystems by the dump(
    command to determine which filesystems need to be dumped.      If the fifth
    field is not present, a value of zero is returned and dump will assume
    that the filesystem does not need to be dumped.

    The sixth field, (fs_passno), is used by the fsck( program to determine
    the order in which filesystem checks are done at reboot time.  The root
    filesystem should be specified with a fs_passno of 1, and other filesys­
    tems should have a fs_passno of 2.  Filesystems within a drive will be
    checked sequentially, but filesystems on different drives will be checked
    at the same time to utilize parallelism available in the hardware.  If
    the sixth field is not present or is zero, a value of zero is returned
    and fsck( will assume that the filesystem does not need to be checked.

    #define FSTAB_RW           "rw"    /* read/write device */
    #define FSTAB_RQ           "rq"    /* read/write with quotas */
    #define FSTAB_RO           "ro"    /* read-only device */
    #define FSTAB_SW           "sw"    /* swap device */
    #define FSTAB_XX           "xx"    /* ignore totally */

    struct fstab {
          char    *fs_spec;           /* block special device name */
          char    *fs_file;           /* filesystem path prefix */
          char    *fs_vfstype;    /* File system type, ufs, nfs */
          char    *fs_mntops;     /* Mount options ala -o */
          char    *fs_type;           /* FSTAB_* from fs_mntops */
          int     fs_freq;           /* dump frequency, in days */
          int     fs_passno;      /* pass number on parallel fsck */
    };

    The proper way to read records from fstab is to use the routines
    getfsent(3), getfsspec(3), getfstype(3), and getfsfile(3).

FILES
    /etc/fstab  The file fstab resides in /etc.

Thanks John
   I had actually found My answer last night it was just late iand I did not post my results. After reading your post I realized I had actually stated my question wrong. What I was trying to do is give me a mount point to view my win95 files and I wanted to put that in the /etc/fstab
I have done this now and everything is ok.

Agian Thanks
