(VPD)
code
stored

Management

(MIF)
Management
Information
Format
(MIF)
is
a
file
used
to
maintain
a
list
of
the
system
unit
serial
number
along
with
all
serialized
components
(for
example,
system
board,
riser
card,
memory,
and
processor).
At
the
time
of
computer
manufacture,
the
EPROM
will
be
loaded
with
the
serial
numbers
of
the
system
and
all
major
components.
A
company
called
Retain-a-Group
is
a
central
data
warehouse
offering
serial
number
data
management.
Retain-a-Group
acts
as
a
focal
point
to
law
enforcement.
The
customer
has
the
option
to
purchase
serial
number
information
and
services
from
Retain-a-Group.
It
is
the
customer’s
responsibility
to
maintain
the
MIF
file
and
to
inform
Retain-a-Group
of
any
changes
to
the
file.
Some
customers
may
request
their
servicers
to
assist
them
in
maintaining
the
MIF
file
when
serialized
components
are
replaced
during
hardware
service.
This
assistance
is
between
the
customer
and
the
servicer.
The
servicer
can
use
the
DMI
MIF
Browser
to
update
the
MIF
information
in
the
EPROM.
It
is
anticipated
that
some
servicers
might
charge
for
this
service.
To
update
the
EPROM
using
the
DMI
MIF
Browser,
use
the
following
procedure.
1.
