+.Sh NAME
+.Nm callbootd
+.Nd Contact boot parameter server for boot parameters
+.Sh SYNOPSIS
+.\" callbootd server procnum (IP-addr | host fileid)
+.\" "usage: callbootd (all | server) [ip_addr | hostname]"
+.Nm
+.Ar server
+.Op ip_addr | hostname
+.Sh DESCRIPTION
+The
+.Nm
+utility is a client application that provides information to
+.Xr diskless 8
+clients necessary for booting.
+.Nm
+runs after the kernel initializes networking
+but before mounting the root filesystem.
+It retrieves hostname, domain, router, and
+NFS boot file information from
+.Xr bootparamd 8 .
+This information is used to configure networking
+and determine the NFS root filesystem.
+.Sh OPTIONS
+.Bl -tag -width Fl
+.It Ar server
+Contact server to request boot parameters.
+If server is "all", then a broadcast message is sent
+to all hosts on the local network.
+Otherwise, if no client IP address or hostname is specified,
+.Nm
+sends a whoami request and prints the client hostname,
+domain_name, and router (default gateway) for each response received.
+.It Op ip_addr | hostname
+Contact 
+.Ar server
+to request the boot server name, boot server address,
+and NFS path associated with the client IP address (ip_addr) or hostname.
+.El
+.Sh EXAMPLES
+To broadcast a request for whoami information:
+.Pp
+.Ql "callbootd all"
+.Pp
+To contact a server at 192.168.0.3 for whoami information:
+.Pp
+.Ql "callbootd 192.168.0.3"
