Debugging
problems
Occasionally,
you
might
have
to
debug
problems
during
the
test
phase
of
your
development
process.
This
chapter
provides
information
about
some
of
the
debugging
tools
provided
by
the
ImageUltra
Builder
program
and
some
best
practices
to
follow
to
avoid
some
problems
that
are
difficult
to
debug.
The
ImageUltra
Builder
image-installation
process
To
debug
a
problem,
you
must
have
some
level
of
understanding
of
the
processes
that
take
place
during
the
image-installation
phase.
All
files
referenced
in
this
section
are
located
either
in
the
service
partition
of
the
target
computer,
or,
in
the
case
of
a
direct-network
installation,
in
the
network-staging
folder.
The
AUTOEXEC.CMD
file
is
the
first
program
launched
at
the
beginning
of
the
image-installation
phase
and
acts
as
the
master
control
program
for
all
activities
during
the
image-installation
phase.
Activities
include
the
following:
1.
Establishing
global
variables
and
PATHs.
2.
Controlling
the
installation
menus.
The
Mapmenu
program
runs
and
processes
the
Before
Menu
Options.
Once
the
Before
Menu
items
are
complete,
all
of
the
menu
items
in
the
basemap
are
displayed.
Once
a
selection
is
made
from
the
basemap,
the
Post
Menu
options
are
processed,
and
the
EXECUTE.CMD
file
is
written
into
the
IUTEMP
directory.
3.
Once
the
menu
processing
is
complete,
the
EXECUTE.CMD
file
runs
to
process
and
queued
utilities
from
the
basemap.
4.
All
of
the
selected
modules
are
written
into
the
AOD.DAT
and
the
process
installs
all
of
the
modules
in
this
file.
5.
Customer-first-boot
module
processing.
Upon
the
successful
completion
of
the
audit
boot,
the
modules
in
the
\IUWORK
folder
are
processed.
Finding
debug
data
in
the
target
computer
user
partition
During
the
image-installation
process,
the
ImageUltra
Builder
program
creates
a
MODULES.LOG
file
in
the
\SWTOOLS
folder
of
the
target
computer
user
partition.
The
MODULES.LOG
provides
a
listing
of
each
module
that
installed
successfully.
If
a
problem
occurs
during
installation,
you
can
use
this
log
to
detect
the
last
module
that
installed
successfully,
and
use
that
as
a
starting
point
for
debugging.
Finding
debug
data
in
the
service
partition
or
network-staging
folder
During
the
image-installation
process,
the
ImageUltra
program
creates
several
logs
in
the
IUTEMP
folder
of
staging
area
(service
partition
or
network-staging
folder).
If
an
error
occurs
during
the
installation
process,
the
installation
process
is
halted,
an
error
message
is
posted,
and
you
can
exit
from
the
installation
process
and
view
the
logs
to
determine
where
the
error
occurred.
The
following
is
a
listing
of
those
logs:
v
The
IUTEMP\STAMP.LOG:
log
contains
time-stamped
entries
for
all
activities
performed
in
the
staging
area
