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
