  92. # client Vendor Class ID.
  93. # Requires DHCP support.
  94. # -DALLOW_ONLY_ENCAPSULATED
  95. # Ignore Etherboot-specific options that are not within

  98. # configuration from the bad old days before the use of

  100. # -DDEFAULT_BOOTFILE=\"default_bootfile_name\"
  101. # Define a default bootfile for the case where your DHCP
  102. # server does not provide the information. Example:
  103. # -DDEFAULT_BOOTFILE="tftp:///tftpboot/kernel"
  104. # If you do not specify this option, then DHCP offers that

  112. # Boot tuning parameters:
  113. #
  114. # -DCONGESTED
  115. # Turns on packet retransmission. Use it on a
  116. # congested network, where the normal operation
  117. # can't boot the image.
  118. # -DBACKOFF_LIMIT
  119. # Sets the maximum RFC951 backoff exponent to n.
  120. # Do not set this unreasonably low, because on networks
  121. # with many machines they can saturate the link
  122. # (the delay corresponding to the exponent is a random
  123. # time in the range 0..3.5*2^n seconds). Use 5 for a
  124. # VERY small network (max. 2 minutes delay), 7 for a
  125. # medium sized network (max. 7.5 minutes delay) or 10
  126. # for a really huge network with many clients, frequent
  127. # congestions (max. 1 hour delay). On average the
  128. # delay time will be half the maximum value. If in
  129. # doubt about the consequences, use a larger value.
  130. # Also keep in mind that the number of retransmissions
  131. # is not changed by this setting, so the default of 20
  132. # may no longer be appropriate. You might need to set
  133. # MAX_ARP_RETRIES, MAX_BOOTP_RETRIES, MAX_TFTP_RETRIES
  134. # and MAX_RPC_RETRIES to a larger value.
  135. # -DTIMEOUT=n
  136. # Use with care!! See above.
  137. # Sets the base of RFC2131 sleep interval to n.
  138. # This can be used with -DBACKOFF_LIMIT=0 to get a small
  139. # and constant (predictable) retry interval for embedded
  140. # devices. This is to achieve short boot delays if both
  141. # the DHCP Server and the embedded device will be powered
  142. # on the same time. Otherwise if the DHCP server is ready
  143. # the client could sleep the next exponentially timeout,
  144. # e.g. 70 seconds or more. This is not what you want.
  145. # n should be a multiple of TICKS_PER_SEC (18).
  146. #
  147. # Boot device options:
  148. #
  149. # -DTRY_FLOPPY_FIRST
  150. # If > 0, tries that many times to read the boot
  151. # sector from a floppy drive before booting from
  152. # ROM. If successful, does a local boot.
  153. # It assumes the floppy is bootable.
  154. # -DEXIT_IF_NO_OFFER
  155. # If no IP offer is obtained, exit and
  156. # let the BIOS continue.
  157. # The accessibility of the TFTP server has no effect,
  158. # so configure your DHCP/BOOTP server properly.
  159. # You should probably reduce MAX_BOOTP_RETRIES
  160. # to a small number like 3.

  171. # Support for receiving multicast packets

  173. # Interface export options:
  174. #
  175. # -DPXE_EXPORT
  176. # Export a PXE API interface. This is work in
  177. # progress. Note that you won't be able to load
  178. # PXE NBPs unless you also use -DPXE_IMAGE.
  179. # -DPXE_STRICT
  180. # Strict(er) compliance with the PXE
  181. # specification as published by Intel. This may
  182. # or may not be a good thing depending on your
  183. # view of the spec...
  184. # -DPXE_DHCP_STRICT
  185. # Strict compliance of the DHCP request packets
  186. # with the PXE specification as published by
  187. # Intel. This may or may not be a good thing
  188. # depending on your view of whether requesting
  189. # vendor options which don't actually exist is
  190. # pointless or not. You probably want this
  191. # option if you intend to use Windows RIS or
  192. # similar.
  193. #
  194. # Obscure options you probably don't need to touch:
  195. #
  196. # -DZPXE_SUFFIX_STRIP
  197. # If the last 5 characters of the filename passed to Etherboot is
  198. # ".zpxe" then strip it off. This is useful in cases where a DHCP server
  199. # is not able to be configured to support conditionals. The way it works
  200. # is that the DHCP server is configured with a filename like
  201. # "foo.nbi.zpxe" so that when PXE asks for a filename it gets that, and
  202. # loads Etherboot from that file. Etherboot then starts up and once
  203. # again asks the DHCP server for a filename and once again gets
  204. # foo.nbi.zpxe, but with this option turned on loads "foo.nbi" instead.
  205. # This allows people to use Etherboot who might not otherwise be able to
  206. # because their DHCP servers won't let them.
