There's a much easier way of doing this.  Get the latest 3.1-STABLE
snapshot from: ftp://releng3.freebsd.org/pub/FreeBSD/snapshots/i386/3.1-...
and pull kern.flp and mfsroot.flp out of the floppies/ subdirectory.
Use dd or fdwrite to whap each onto a floppy disk in the usual way and
then mount the kernel floppy as follows:

     mount /dev/fd0 /mnt

Now compile up a 3.1-stable kernel containing your IDA drivers and
be sure to include:

     options MFS
     options MFS_ROOT

In its config file.  Take the resulting kernel, gzip it and then and
copy kernel.gz to /mnt, overwriting the kernel that's there.
``umount /mnt'', pop the floppy out, walk over to your installation
machine and boot from it.  When prompted, insert the mfsroot floppy as
normal and then proceed into the installation.  If everything goes
smoothly, you should see and be able to install onto your drives.  If
you want to do an FTP installation, select the releng3.freebsd.org server
from the FTP servers list and it will also load the appropriate snapshot
that goes with the original boot floppies.

Now that the boot floppies are no longer "magic" (one nice consequence
of going to 2 floppies), you can replace that kern.flp kernel with any
one you like, just so long as the MFS and MFS_ROOT options are
included.  You also have the option of gzipping or not gzipping it,
depending on size - the loader will deal with it either way.
