Assuming that you have a working %%FreeBSD%% DHCP/NFS server on 192.168.1.10 already configured and that your network is 192.168.1.0/255.255.255.0

I also assume that you can access the serial console of the machine to be netbooted from the host via tip(1), conserver-com, etc.

  * DHCP configuration

<code>
host testbox {
     fixed-address 192.168.1.101;
     hardware ethernet 00:16:3e:00:00:04;
     next-server 192.168.1.10;
     filename "pxeboot.9";
     option root-path "192.168.1.10:/pxeroot/9.0-RELEASE/";
}
</code>

  * PXE/TFTP inetd.conf
    * copy /boot/pxeboot from the ISO to /tftpboot/pxeboot.9

<code>
tftp    dgram   udp     wait    root    /usr/libexec/tftpd      tftpd -l -s /tftpboot
</code>

  * NFS Dir
    * mkdir /pxeroot/9.0-RELEASE
    * mdconfig -f [9.0 DVD ISO]
    * mkdir /tmp/iso
    * mount -t cd9660 /dev/md0 /tmp/iso
    * cp -r /tmp/iso/* /pxeroot/9.0-RELEASE
    * umount /tmp/iso
    * mdconfig -d -u 0
    * cd /pxeroot/9.0-RELEASE
    * Edit for serial console in netboot environment
      * /pxeroot/9.0-RELEASE/boot.config
        * -Dh
      * /pxeroot/9.0-RELEASE/boot/loader.conf
        * console="comconsole"
      * /pxeroot/9.0-RELEASE/etc/ttys
        * change ttyu0 entry to

<code>
ttyu0   "/usr/libexec/getty std.9600"   vt100   on secure
</code>

  * /etc/fstab

<code>
#/dev/iso9660/FREEBSD_INSTALL / cd9660 ro 0 0
192.168.1.10:/pxeroot/9.0-RELEASE/ / nfs ro 0 0
</code>

  * NFS server /etc/exports
    * /pxeroot/9.0-RELEASE -alldirs -maproot=0 -network 192.168.1.0 -mask 255.255.255.0
    * restart nfs server /etc/rc.d/nfsserver restart

  * Access the console of the host to be installed via netboot(tip, conserver, minicom, etc...)
  * Power the host on and verify that the host pxeboot's into the installer and follow the instructions from there.
  * Change the entry in your dhcpd.conf to something like the following:

<code>
host testbox {
     fixed-address 192.168.1.101;
     hardware ethernet 00:16:3e:00:00:04;
     #next-server 192.168.1.10;
     #filename "pxeboot.9";
     #option root-path "192.168.1.10:/pxeroot/9.0-RELEASE/";
}
</code>

  * Before rebooting after the install is complete, you must setup your serial console manually at this time
  * At the last menu, drop to a chroot'd shell on the freshly installed system
    * /etc/ttys
      * change ttyu0 entry to

<code>
ttyu0   "/usr/libexec/getty std.9600"   vt100   on secure
</code>

  * /boot.config
    * -Dh
  * /boot/loader.conf
    * console="comconsole"
