There is no system interface for PC's that allows you to determine
an amount of memory over 64M. In general, this limit is 32M (for
the sign bit) and 16M on Compaq and Dell systems, which use the
CMOS bits for other things.
There are compilation options that allow you to override the
probe reported amount (freefall.cdrom.com was 196M or so at
one time; maybe it still is).
For FreeBSD, you should look at /sys/i386/conf/LINT, which documents
the option (assuming you are running a recent release).
