Problem determination tips Because there is a large variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. v Verify any recent hardware changes. See "Hardware considerations" on page 108. v Verify any recent software changes. See "Software considerations" on page 107. v Verify that the BIOS is at the latest level. See "BIOS" on page 107. v Verify that the drivers are at the latest levels. See "Drivers" on page 107. v Verify that the Configuration matches the hardware. See "System resource conflicts" on page 109. v Verify that the Diagnostics diskette is at the latest level. See "File updates." As you go through problem determination, consider these questions. v Do diagnostics fail? v What, when, where, single, or multiple systems? v Is the failure repeatable? v Has this configuration ever worked? v If it has been working, what changes were made prior to it failing? v Is this the original reported failure? Important To eliminate confusion, systems are considered identical only if the following are exactly identical for each system: 1. Machine type and model 2. BIOS level 3. Adapters/attachments (in same locations) 4. Address jumpers/terminators/cabling 5. Software versions and levels 6. Reference/Diagnostics Diskette 7. Configuration options set in the system 8. Setup for operation system control files Comparing the configuration and software setup between "working" and "non-working" systems will often resolve problems. File updates Use the IBM support area on the World Wide Web (WWW) to download Diagnostic, BIOS Flash, and Device Driver files. http://www.ibm.com/support Adding adapters to the system When adapters are added to the system, an area in memory has to be allocated to run its programs. This can be done with either hardware switches or software mapping. If there is a conflict in software mapping, then the following may be true. v The first device to attach to an IRQ, DMA, I/O Address, or RAM location will probably function. The second device will not be found. 106 Hardware Maintenance Manual

Problem
determination
tips
Because
there
is
a
large
variety
of
hardware
and
software
combinations
that
can
be
encountered,
use
the
following
information
to
assist
you
in
problem
determination.
v
Verify
any
recent
hardware
changes.
See
“Hardware
considerations”
on
page
108.
v
Verify
any
recent
software
changes.
See
“Software
considerations”
on
page
107.
v
Verify
that
the
BIOS
is
at
the
latest
level.
See
“BIOS”
on
page
107.
v
Verify
that
the
drivers
are
at
the
latest
levels.
See
“Drivers”
on
page
107.
v
Verify
that
the
Configuration
matches
the
hardware.
See
“System
resource
conflicts”
on
page
109.
v
Verify
that
the
Diagnostics
diskette
is
at
the
latest
level.
See
“File
updates.”
As
you
go
through
problem
determination,
consider
these
questions.
v
Do
diagnostics
fail?
v
What,
when,
where,
single,
or
multiple
systems?
v
Is
the
failure
repeatable?
v
Has
this
configuration
ever
worked?
v
If
it
has
been
working,
what
changes
were
made
prior
to
it
failing?
v
Is
this
the
original
reported
failure?
Important
To
eliminate
confusion,
systems
are
considered
identical
only
if
the
following
are
exactly
identical
for
each
system:
1.
Machine
type
and
model
2.
BIOS
level
3.
Adapters/attachments
(in
same
locations)
4.
Address
jumpers/terminators/cabling
5.
Software
versions
and
levels
6.
Reference/Diagnostics
Diskette
7.
Configuration
options
set
in
the
system
8.
Setup
for
operation
system
control
files
Comparing
the
configuration
and
software
setup
between
“working”
and
“non-working”
systems
will
often
resolve
problems.
File
updates
Use
the
IBM
support
area
on
the
World
Wide
Web
(WWW)
to
download
Diagnostic,
BIOS
Flash,
and
Device
Driver
files.
Adding
adapters
to
the
system
When
adapters
are
added
to
the
system,
an
area
in
memory
has
to
be
allocated
to
run
its
programs.
This
can
be
done
with
either
hardware
switches
or
software
mapping
.
If
there
is
a
conflict
in
software
mapping,
then
the
following
may
be
true.
v
The
first
device
to
attach
to
an
IRQ,
DMA,
I/O
Address,
or
RAM
location
will
probably
function.
The
second
device
will
not
be
found.
