16 MB of RAM detected instead of 90 MB

Hi,
I installed freeBSD on a Compaq proliant 800 with 90MB of ram
but the system only sees 16 MB
I don't have a clue about this OS , but maybe someone could help me ?
Thanks in advance.

        Your BIOS is brain dead.  That's ok, you can work around it.  Add
        this to your kernel config (/usr/src/sys/i386/conf/MYCONFIG):

                options "MAXMEM=(90*1024)"

        If this freaks or locks up when you restart, your BIOS is also
        stealing a bit of RAM that makes the above math invalid.  Not many
        machines have this problem, but a few do (my ThinkPad does). To fix
        it if it happends, use:

                options "MAXMEM=(89*1024)"

        If you're worried about losing that part of a MB, when the machine
        boots take note of the *exact* number of bytes of memory test/found
        and use that instead of the above calculation.

Berkeley or thereabouts.  Similar in many ways to the prescription-only
medication called "System V", but infinitely more useful. (Or, at least,
more fun.)  The full chemical name is "Berkeley Standard Distribution".

        Reset you bios to defaults and dont play around with bios anymore.
        It could be the "memory hole" good old faq.
        If not, your ram modules are not Compaq certifed (read more $$$$$$)
