You need a RARP daemon (since this is what the Sun firmware uses to
find out about its own IP address), a DHCP server (that's what FreeBSD
uses to find about its boot parameters -- Solaris would use
rpc.bootparamd instead), and a TFTP server to supply the bootstrap.
Finally (and obviously), you need an NFS server supplying the

Configuring the RARP daemon is simple: setup /etc/ethers, and enable
it in your /etc/inetd.conf.  If you've got an ethernet interface with
more than one IP address, you might want to obtain FreeBSD's latest
version of rarpd.

Here's a snippet of dhcpd.conf (ISC DHCP) I've been using to netboot
one of my machines:

        hardware ethernet 08:00:20:XX:XX:XX;
        fixed-address HOSTNAME;
        option host-name "HOSTNAME";
        always-reply-rfc1048 on;
        filename "kernel";
        option root-path "SERVERIPADDRESS:/cdrom";

HOSTNAME is the intented name of your host (should be in DNS in order
to be used for `fixed-address', too).  Note the use of an IP address
for SERVERIPADDRESS -- this avoids the requirement of DNS lookups when
mounting the root FS.  In the above case, the boot server was serving
the image of the installation CD-ROM for a machine that was unwilling
to boot directly off that CD.  (You can read about it in the archives
of this list.)

The TFTP server must be the same machine that runs rarpd, and the boot
image must have the hexadecimal client's IP address as its name (using
the TFTP daemon's default directory, typically /tftpboot).  The actual
file to supply is /boot/loader (right from the CD-ROM in my case).
This is normally done using a symlink from /tftpboot/loader to
/tftpboot/C0A80301 (example:

That's about all, type "boot net" then on your client.

I think so, since the SCSI controller isn't supported at all (as
I understand the docs).

I've got an E450 as my machine to play with FreeBSD/sparc64... but
even if I could give it away, shipping it overseas alone would
probably exceed the current value of that machine.  It's large and
