Use 5 for a # VERY small network (max. 2 minutes delay), 7 for a # medium sized network (max. 7.5 minutes delay) or 10 # for a really huge network with many clients, frequent # congestions (max. 1 hour delay).

See above. # Sets the base of RFC2131 sleep interval to n. # This can be used with -DBACKOFF_LIMIT=0 to get a small # and constant (predictable) retry interval for embedded # devices.

This is useful in cases where a DHCP server # is not able to be configured to support conditionals. The way it works # is that the DHCP server is configured with a filename like # "foo.nbi.zpxe" so that when PXE asks for a filename it gets that, and # loads Etherboot from that file. Etherboot then starts up and once # again asks the DHCP server for a filename and once again gets # foo.nbi.zpxe, but with this option turned on loads "foo.nbi" instead. # This allows people to use Etherboot who might not otherwise be able to # because their DHCP servers won't let them. # # -DPOWERSAVE # Halt the processor when waiting for keyboard input # which saves power while waiting for user interaction. # Good for compute clusters and VMware emulation. # But may not work for all CPUs. # -DBUILD_SERIAL # Include an auto-incrementing build number in # the Etherboot welcome message.
