Format,

The
Intel
OMF286
format
is
a
dynamically
allocatable
file
format.
This
format
has
three
basic
parts:
the
file
header,
data
file
module,
and
a
1-byte
checksum.
The
file
header
is
hexadecimal
number
(A2)
that
identifies
this
file
as
an
Intel
OMF
286
format
file.
See
Figure
D-23.

A
Sample
of
the
Intel
OMF286
Format
The
first
75
bytes
of
the
data
file
module
is
the
data
file
header.
The
header
information
is
generated
and
used
by
the
development
system
and
is
not
used
by
the
programmer,
although
some
characters
must
fill
those
bytes.
The
rest
of
the
data
file
module
consists
of
one
partition.
The
partition
begins
with
a
20
byte
table
of
contents.
The
table
of
contents
specifies
the
locations
of
ABSTXT
(absolute
text),
DEBTXT
(debug
text),
the
last
location
of
this
partition,
and
the
location
of
the
next
partition.
The
OMF286
format
consists
of
only
one
partition
so
this
field
will
be
zeros.
The
rest
of
the
partition
consists
of
sections.
The
actual
data
are
located
in
the
sections.
The
first
3
bytes
in
each
section
specify
the
real
address
of
the
text.
The
next
2
bytes
state
the
length
of
the
text,
and
the
remainder
of
the
section
is
the
text
(or
data).
Following
the
final
section
of
the
final
partition
is
a
1-byte
checksum
representing
the
complement
of
the
sum
of
all
the
bytes
in
the
file,
including
the
header.
The
sum
of
the
checksum
byte
and
the
calculated
checksum
for
the
file
should
equal
zero.
The
programmer
ignores
this
checksum.
