Thanks to Henryk Mickalec for all the help. His response pointed me to
the error in a matter of few hours after I had spent several days
on the problem.
The original problem was getting a sparc1 to boot from
a server running sunos 4.1.3_U1. I had several problems
that had to be corrected but was finally able to get
the system up and running.
The summary is as follows: ( the complete question and response is below)
1.) the tftp deamon was commented out of the inetd.conf file.
2.) the tftpboot directory did not contian the file boot.sun4c.sunos.4.1.3_u1
but rather the boot.sun4m....
3.) After putting the correct file in the tftpboot dir a syymbolic link to
the ip address of the sparc1 (in hex) was created to the boot.sun4c.... file.
That was it.

I assume, you haven't got S630 configured as a server for diskless clients.

In normal way server require several additional features:
1. Additional partitions for "root" and "swap" directories, usually
/export/root and /export/swap. "/export/root" contain "root" filesystem
for diskless, e.g. if if diskless hostname is "pluto", the root filesystem
begins form /export/root/pluto . "/export/swap" contain "swap-files", e.g.
/export/swap/pluto. It is not necessary to have separate partitions for
/export and /export/swap, but this is the simple way (system installation
2. Server must support ARP and TFTP services. You must put into /etc/ethers
file entry for diskless machine, e.g.:
where pluto is in your /etc/hosts, e.g.
In /tftpboot directory you must have boot file for proper architecture:
lrwxrwxrwx 1 root 25 Sep 1 11:39 C0950303 -> boot.sun4c.sunos.4.1.3_U1
lrwxrwxrwx 1 root 25 Sep 1 11:39 C0950303.SUN4C -> boot.sun4c.sunos.4.1.3_U1
-rwxr-xr-x 1 root 110352 Sep 1 11:39 boot.sun4c.sunos.4.1.3_U1
-rwxr-xr-x 1 root 103512 Sep 1 11:34 boot.sun4m.sunos.4.1.3_U1
lrwxrwxrwx 1 root 1 Sep 1 11:07 tftpboot -> .
For TFTP service configuration check /etc/inetd.conf file for uncommented entry:
tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -s /tftpboot
3. In /etc must be /etc/bootparams file:
(The server name is "srv")
I hope, this can help you. Most proper advices I will send if I will have
messages form diskless.
