Is there a unique host id in ROM?

[Samuel C Kendall]

If so, how do I read it?  The systems on which I need to do this are:

	 any VAX running Ultrix  
	 any VAX running 4.3 BSD 
	 any DECS MIPS machine 

In the Ultrix documentation I've found some mention of reading ROMs,
but no map of the ROM's contents.

I need this in order to lock a piece of software (a license server) to
a particular host.  On Suns, gethostid(2) does the trick; but since 4.3
BSD and Ultrix have a sethostid(2) system call, I don't think gethostid
is very secure there!

Please reply by mail.
