I was able to return from the get_partition_info function without
problem by using your partition table.  Stephen, if time permits could
you find out why the condition:

if ((pt->sys_ind != 0) && (part_num == which_part) && 
	(is_extended(pt->sys_ind) == 0))

was not true (I assumed this since this is the only place where it will
return a valid value).

Anyone who also had problems with this before?  Wolfgang?  Thanks in
advance.
