Kinda thought it might.  When I first got my MO I was running Windows 
3.11, and discovered that starting Windows without a disk in the drive 
guaranteed a lockup.  I very quickly got into the habit of just leaving a 
disk in there until I want to stick a different one in.  As a result, I've 
never tried booting Win95 or FreeBSD without a disk in the MO, because 
there is ALWAYS one in there.

What's the capacity of the drive supposed to be?
In any case, you may not need to worry about that too much.  Try mounting 
a disk and see if it works.  If it does, be happy.  :)
If it doesn't...  I don't know enough about the internals of FreeBSD to 
take this much further.  Maybe someone else here has some ideas.
