	Yeah, me too on all the previous systems I built and manage since
atleast 6 years ago, without MAXMEM, it will not show memory above 64 megs
so I continued to use it until I decided to build new systems for others
and the MAXMEM option gave the problem while without the option, it seems
to be fine and shows all memory.
