Problem determination tips Due to the variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. If possible, have this information available when requesting assistance from Service Support and Engineering functions. v Machine type and model v Processor or hard disk upgrades v Failure symptom - Do diagnostics fail? - What, when, where, single, or multiple systems? - Is the failure repeatable? - Has this configuration ever worked? - If it has been working, what changes were made prior to it failing? - Is this the original reported failure? v Reference/Diagnostics version - Type and version level v Hardware configuration - Print (print screen) configuration currently in use - BIOS level v Operating system software - Type and version level Note: To eliminate confusion, identical systems are considered identical only if they: 1. Are the exact machine type and models 2. Have the same BIOS level 3. Have the same adapters/attachments in the same locations 4. Have the same address jumpers/terminators/cabling 5. Have the same software versions and levels 6. Have the same Reference/Diagnostics Diskette (version) 7. Have the same configuration options set in the system 8. Have the same setup for the operation system control files Comparing the configuration and software set-up between ″working and non-working″ systems will often lead to problem resolution.

of
hardware
and
software
combinations
that
can
be
encountered,
use
the
following
information
to
assist
you
in
problem

If
possible,
have

available
when
requesting
assistance
from

v
Failure
symptom
Do
diagnostics
fail?
What,
when,
where,
single,
or
multiple
systems?
Is
the
failure
repeatable?
Has
this
configuration
ever
worked?
If
it
has
been
working,
what
changes
were
made
prior
to
it
failing?
Is
this
the
original

Note:
To
eliminate
confusion,
identical
systems
are
considered
identical
only
if
they:
1.
Are
the
exact
machine
type
and
models
2.
Have
the
same
BIOS
level
3.
Have
the
same
adapters/attachments
in
the
same
locations
4.
Have
the
same

5.
Have
the
same

versions
and

6.
Have

Have
the
same

options
set
in
the
system
8.
Have
the
same
setup
for
the

Comparing
the
configuration
and
software
set-up
between
working
and
non-working
systems
will
often
lead
to
problem
resolution.
