-.I Bootpd
+.B Bootpd
 implements an Internet Bootstrap Protocol (BOOTP) server as defined in
-RFC951, RFC1532, and RFC1533.
-.I Bootpgw
+RFC951, RFC1532, and RFC1533. This server also provides some extension
+to support the static part of Dynamic Host Configuration Protocol (DHCP)
+as specified in RFC1533. DHCP is used by Windows NT and 95.
+.B Bootpgw
 implements a simple BOOTP gateway which can be used to forward
 requests and responses between clients on one subnet and a
 BOOTP server (i.e.
-.IR bootpd )
+.BR bootpd )
 on another subnet. While either
-.I bootpd
+.B bootpd

 Standalone mode is particularly useful when

 (Automatic start up in standalone mode can be done by invoking

 Both

 They differ in their handling of BOOTREQUEST packets.

+Description: server for the bootp protocol with DHCP support
+ This is a server for the bootp protocol; which allows network administrator
+ to setup networking information for clients via an /etc/bootptab on a server
+ so that the clients can automatically get their networking information.  While
+ this server includes rudimentary DHCP support as well, we suggest using the
+ dhcp package if you need DHCP support, as it is much more complete.
