3.3MB?
Can you re-check the amount of memory in the machine?
Is the memory in this machine known good and working?
16MB is what I'd regard as a bare minimum for FreeBSD these days.

There is a problem of some kind but not enough information to diagnose it.

The suggestions by others on this list to try booting a regular FreeBSD
4.9 CD, or even FreeSBIE, are most helpful here.

Can you post the traceback in full to me off-list? You may need to use
a serial console and null-modem cable to get this info, please see:
