This function copies new software from an external medium to the Flash
ROM on the machine's FCE. The external medium for new software can be
an FCE or an EPROM board.
1. Turn off the machine, remove the NCU cover, the left cover, and the front
cover, then remove the IC page memory card from the FCE.
Do this only if

block. See the note at
the end of this
procedure.
2. Insert the Flash/SRAM Copy Tool [A] into the IC card slot [B], then con-
nect the FCE or EPROM board with new software [C] to the opposite side
of the tool.
