下記コードを、"overview_display.c"の void display_overview(void)
の後半に加えてください。

****************************************************

	printf("<div class=\"system_box\">\n");
	printf("<h4>File Upload Test</h4>\n");
	printf("<div>" );
	printf("<form method=\"post\" enctype=\"multipart/form-data\" action=\"http:/admin/fileup.cgi\">" );
	printf("<input type=\"file\" name=\"file_save_data\" size=\"64\" class=\"file\" tabindex=\"1\" />" );
	printf("<input type=\"submit\" name=\"file_save\" value=\"SUBMIT\" tabindex=\"2\" />" );
