Read this for the details:

The older BIOS ABI only had enough bits to report 64 MB as a maximum
amount of ram installed.  At the time the programmers certainly said
to themselves, "Who would ever have that much ram installed?"  :-)

You will probably need to supply the correct amount of memory as an
option to the kernel at boot time.  I will assume you are using lilo
as that is the default.  Put this in your /etc/lilo.conf file and then
run lilo.

  append="mem=128M"
  lilo
