how to recover host-id in solaris 8.0

Hello to everybody,

In sun ultra-10 workstation the NVRAM has failed
that is while switching on the machine there is no
display, no beep and i have confirmed the problem
in NVRAM by installing an other working NVRAM, in that case the machine is booting properly. Now i
have the ” C compiler installed and the liscence
is dependent on the host-id. Is there anyway i can
get back the original host-id that is if it is stored in any log file?. In case iam not able to get back the host-id howto make the ” C compiler
work?. Please help me.

Regards
