Filters
Filters
automate
a
decision
during
the
installation
process.
You
typically
use
filters
to
obtain
hardware-related
information
from
a
target
computer
to
determine
if
a
specific
module
or
set
of
modules
should
be
installed.
The
ImageUltra
Builder
program
provides
filters
that
check
the
machine
type,
machine
type
and
model
number,
hardware
platform
(mobile
or
desktop),
and
whether
or
not
a
computer
is
an
Lenovo
branded
computer.
You
can
also
develop
your
own
filters
if
needed.
Filters
are
Win32-based
programs
that
run
during
the
installation
process.
In
most
cases
filters
query
the
BIOS
of
the
target
computer,
but
they
can
query
other
devices
that
store
identification
information
in
a
ROM
or
EEPROM
module.
For
example,
you
might
want
to
check
for
the
presence
of
a
PCI
modem
before
installing
a
modem-related
application
program
or
you
might
want
to
check
for
a
specific
machine
type
to
determine
which
device
drivers
should
be
installed.
You
can
implement
filters
two
different
ways:
v
Assign
a
filter
to
a
menu
item
in
either
a
base
map
or
driver
map
by
using
the
Filter
tab
attributes
for
the
menu
item.
v
Assign
a
filter
directly
to
an
application
or
device-driver
module
by
using
the
Filter-tab
attributes
for
that
specific
module.
Using
filters
enables
you
to
develop
one
map
that
works
across
many
computer
types.
For
information
about
creating
your
own
filters
or
information
about
using
the
filters
provided
with
the
ImageUltra
Builder
program,
refer
to
the
ImageUltra
Builder
help
system.
Utilities
Utilities
are
Win32-based
EXE,
BAT,
or
COM
files
that
run
during
the
installation
process.
For
example,
an
installer
might
want
to
run
CHKDSK
to
determine
the
size
and
condition
of
a
hard
disk
before
any
files
get
installed.
Utilities
are
copied
to
the
service
partition
of
the
target
computer
during
deployment,
run
during
the
installation
process,
but
never
get
copied
to
the
active
partition
of
the
target
computer.
You
can
incorporate
utilities
in
a
map
to
run
immediately
before
the
installation
menus,
immediately
after
the
installation
menus,
or
as
a
result
of
a
selection
in
the
installation
menus.
You
determine
how
the
utilities
run
and
the
order
in
which
they
run.
The
ImageUltra
Builder
program
does
not
provide
any
utilities.
If
you
want
to
include
utilities,
you
will
have
to
build
your
own
utility
modules.
To
use
a
utility,
you
either
assign
a
utility
module
to
a
base-map
menu
item
or
use
the
Before/After
Menu
tab
in
the
Map
Settings
window
for
base
maps.
