NAME

       disktab - disk description file

SYNOPSIS

       #include <disktab.h>

DESCRIPTION

       Disktab	is a simple date base which describes disk geometries and disk partition characteristics.  The format is patterned after the term-
       cap(5) terminal data base.  Entries in disktab consist of a number of `:' separated fields.  The first entry for each disk gives the  names
       which are known for the disk, separated by `|' characters.  The last name given should be a long name fully identifying the disk.

       The following list indicates the normal values stored for each disk entry.

       Name  Type  Description
       ns    num   Number of sectors per track
       nt    num   Number of tracks per cylinder
       nc    num   Total number of cylinders on the disk
       b0    str   Filename of block zero primary bootstrap for device
       ba    num   Block size for partition `a' (bytes)
       bd    num   Block size for partition `d' (bytes)
       be    num   Block size for partition `e' (bytes)
       bf    num   Block size for partition `f' (bytes)
       bg    num   Block size for partition `g' (bytes)
       bh    num   Block size for partition `h' (bytes)
       fa    num   Fragment size for partition `a' (bytes)
