The
CD-ROM
drive,
SCSI
cable,
SCSI
adapter,
graphics
adapter,
or
the
primary
I/O
planar
is
most
likely
defective.
A
TTY
terminal
attached
to
the
serial
port
also
can
be
used
to
determine
if
the
graphics
adapter
is
causing
the
problem.
This
is
done
by
removing
the
graphics
adapter,
attaching
a
TTY
to
the
serial
port,
and
retrying
standalone
diagnostics.
If
the
standalone
diagnostics
load,
replace
the
graphics
adapter.
1.
Replace
the
CD-ROM
drive.
2.
Replace
the
SCSI
cable.
3.
If
the
CD-ROM
drive
is
attached
to
a
SCSI
adapter
rather
than
the
integrated
SCSI
on
the
system
board,
replace
the
SCSI
adapter.
4.
Replace
the
primary
I/O
planar.
5.
If
you
replaced
the
indicated
FRUs
and
the
problem
is
still
not
corrected,
or
the
above
descriptions
did
not
address
your
particular
situation,
