Page 336 highlights

DHCP Reference Option #6: Domain Name Server (DNS). Option #12: Computer host name. This value is used by Neoware Image Manager as the TCP/IP host name and also as the NetBIOS computer name (Windows computer name). Option #44: WINS Server. Option #132: Used by mPXELdr to get a list of server IP addresses (optionally followed by a colon (:) and a port number. If no colon and port number is specified, standard NVD port UDP 2184 is used) that can respond to NVDD requests. mPXELdr will try each of the IP addresses listed in this option, in the order in which they appear, until it finds a server that answers and that actually serves at least one bootable virtual drive to the client. This IP address (and optionally this port) is used afterwards as the IP address for the Neoware Image Manager server for this client. If this DHCP option is not specified or is empty, or if none of the server IP addresses sent by this option answers to mPXELdr requests, mPXELdr then tries to use the IP address of the TFTP server that sent mPXELdr to the client, as the NVDD server, unless the list ends with an exclamation mark (!) character (in which case it will then loop to the first server in the list). The actual list of server IP addresses that mPXELdr tries to contact is in the following order: , nextserver (DHCP Option #66) If you do not end the list in DHCP option #132 with an exclamation mark (!), remember that mPXELdr will try to mount virtual drives hosted on the server that provided TFTP service. By default, the BDRUPD.sys driver reads the DHCP options and tries to identify them. If the option is a known one, it is processed (i.e. the 320 Native DHCP Options

DHCP Reference

Native DHCP Options
Option #6
:
Domain Name Server (DNS).
Option #12
:
Computer host name. This value is used by Neoware
Image Manager as the TCP/IP host name and also as
the NetBIOS computer name (Windows computer
name).
Option #44
:
WINS Server.
Option #132
:
Used by mPXELdr to get a list of server IP addresses
(optionally followed by a colon (:) and a port number.
If no colon and port number is specified, standard
NVD port UDP 2184 is used) that can respond to
NVDD requests. mPXELdr will try each of the IP
addresses listed in this option, in the order in which
they appear, until it finds a server that answers and
that actually serves at least one bootable virtual drive
to the client. This IP address (and optionally this port)
is used afterwards as the IP address for the Neoware
Image Manager server for this client. If this DHCP
option is not specified or is empty, or if none of the
server IP addresses sent by this option answers to
mPXELdr
requests, mPXELdr then tries to use the IP
address of the TFTP server that sent mPXELdr to the
client, as the NVDD server, unless the list ends with
an exclamation mark (!) character (in which case it
will then loop to the first server in the list). The actual
list of server IP addresses that mPXELdr tries to con-
tact is in the following order:
<IP addresses in DHCP Option#132>, next-
server (DHCP Option #66)
If you do not end the list in DHCP option #132 with
an exclamation mark (!), remember that mPXELdr
will try to mount virtual drives hosted on the server
that provided TFTP service.
By default, the
BDRUPD.sys
driver reads the DHCP options and tries
to identify them. If the option is a known one, it is processed (i.e. the
