Sequence” setting and make sure that it is set to
Smart or Conventional. If it is set to Hard Disk,
change the setting to Smart or Conventional to set

following procedure.
If you change the user’s setting, make a note of the
setting before changing it.

charged battery pack.
4. Insert the Flash update diskette in drive A.
