programs
with
either
no
mouse
or
a
mouse
attached
to
the
BladeCenter
unit
that
is
not
controlled
by
the
blade
server,
you
will
not
be

of
the

If
the
diagnostic
programs
do
not
detect
any

remains
during
normal
server
operations,
a
software
error
might
be
the
cause.
If
you
suspect
a
software
problem,
see
the
information
that
comes
with
the
software
package.

does
not
work
with
preformatted
