Command:   fdisk - partition a hard disk [IBM]
Syntax:    fdisk [-hm] [-sn] [file]
Flags:     -h  Number of disk heads is m
           -s  Number of sectors per track is n
Examples:  fdisk /dev/hd0           # Examine disk partitions
           fdisk -h9 /dev/hd0       # Examine disk with 9 heads

     When fdisk starts up, it reads in the partition table and  displays
it.   It  then  presents  a menu to allow the user to modify partitions,
store the partition table on a file, or load it from a file.  Partitions
can  be  marked as MINIX, DOS or other, as well as active or not.  Using
fdisk is self-explanatory. However, be aware that repartitioning a  disk
will   cause  information  on  it  to  be  lost.  Rebooting  the  system
immediately is mandatory after changing partition sizes and  parameters.
MINIX,  XENIX,  PC-IX, and MS-DOS all have different partition numbering
schemes.  Thus when using multiple systems on the same disk, be careful.

     Note that MINIX, unlike MS-DOS, cannot access the last sector in  a
partition  with an odd number of sectors.  The reason that odd partition
sizes do not cause a problem with MS-DOS is that MS-DOS  allocates  disk
space in units of 512-byte sectors, whereas MINIX uses 1K blocks.  Fdisk
has a variety of other features that can be seen by typing h.

     Fdisk normally knows the geometry  of  the  device  by  asking  the
driver.   You  can  use  the  -h  and -s options to override the numbers
found.
