Not automatically, but you can manually boot. Assuming your FreeBSD root file system is on the second SCSI disk (sd1), insert the installation floppy, then say at the Boot: prompt: 4:sd(1,a)/kernel (The `4' means `5th BIOS disk'.) Yesterday I decided that that couldnt work, but now that you say it explicitly, I tried, and it doesnt work. (Yields an infinite string of Error C:0 H:0 S:0 error messages.) My BIOS only knows about disks 0 and 1, so anything booted directly must come from there, or from floppy. So, my Linux kernels live on disk 1 and get a boot parameter to tell them which partition on which disk is to be mounted as root directory. I am searching for the way to communicate to a FreeBSD kernel what device contains the root file system. Booting from the install floppy I can choose the fixit item in the menu and get a shell prompt, but it is really a very meagre system one gets, hardly the way to run FreeBSD. Being an absolute beginner with FreeBSD (although with 20+ years of Unix experience) I also experience a lack of information. For example: what is the naming scheme for disks and partitions and slices? The Handbook doesnt tell me. Is there a man page? I made some plausible guesses and sometimes mount accepted them, sometimes not. I have not been able to mount any non-ufs file system. Attempts like `mount -t msdos dev dir' fail because mount tries to execute /sbin/mount_msdos which doesn't exist. But running /mnt/sbin/mount_msdos by hand also fails, I don't know why. Andries
