Thank you guys, that seems easy to do...but I don't have access to
/etc/boot.conf : all I have is a disk image generated by bximage,
which I can't mount !!

The pb is that with my new install the SDL window doesn't work any
more : qemu says "Could not initialize SDL - exit". I did "xhost +"
but didn't change any thing ?!  Anyway I am not spending any more time
to get the SDL window which I don't really need :-)

So basically what I want to do now is mount the freeBSD image in a
loopback and modify the boot.conf file directly. Anyone knows how to
do this under linux (2.6 if relevant) ? BSD seems to have a "weird"
way of organizing the disk. Which file system shoud I support ?

Thanks,
Aziz
