When discovering an IP address via bootp for an NCD terminal on a token ring
network, the 'sa' tag in the bootptab entry must be used.  The 'sa' tag is
for the TFTP server address.

For example, if an NCD resolves its IP address and downloads its boot image
from host 138.43.214.7, then the 'sa' flag should be as follows:

	sa=192.43.157.7

NOTE: The 'sa' tag must be in each individual node definition and not in
      a global definition.

An example of an entire bootp entry is as follows:

	ncd248tr:\
		ht=token-ring:\
		sa=192.43.157.7:\
		sm=255.255.240.000:\
		gw=138.43.208.1:\
		tc=global.tr:\
		ha=0000e588380E:\
		ip=138.43.208.160:\
		hd=/tftpboot/Xncd.3.1.AK:\
		bf=Xncd19c:

Symptoms of this not being set in the bootptab file is the bootp process
answering all of the NCD BOOTREQUEST's without the NCD picking up any of
the BOOTPREPLY's.
