Format,
Code
98
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.
Figure

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.

The
six
record
types
are
described
below.
This
record
begins
with
the
colon
start
character,
which
is
followed
by
the
byte
count
(in
hex
notation),
the
address
of
the
first
data
byte,
and
the
record
type
(equal
to
00).
Following
these
are
the
data
bytes.
The
checksum
follows
the
data
bytes
and
is
the
two's
complement
(in
binary)
of
the
preceding
bytes
in
the
record,
including
the
byte
count,
address,
record
type,
and
data
bytes.
This
end-of-file
record
also
begins
with
the
colon
start
character
and
is
followed
by
the
byte
count
(equal
to
00),
the
address
(equal
to
0000),
the
record
type
(equal
to
01),
and
the
checksum,
FF.
This
is
added
to
the
offset
to
determine
the
absolute
destination
address.
The
address
field
for
this
record
must
contain
ASCII
zeros
(Hex
30s).
This
record
type
defines
bits
4
to
19
of
the
segment
base
address.
It
can
appear
randomly
anywhere
within
the
object
file
and
affects
the
absolute
memory
address
of
subsequent
data
records
in
the
file.
The
following
example
illustrates
how
the
extended
segment
address
is
used
to
determine
a
byte
address.
