Yes i know that made almost no sense, but i hope you understand what i'm asking. Or is it all UTSL? thanks, -Alfred > > -- > John Birrell - jb@cimlogic.com.au; jb@freebsd.org http://www.cimlogic.com.au/ > CIMlogic Pty Ltd, GPO Box 117A, Melbourne Vic 3001, Australia +61 418 353 137 > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-sparc" in the body of the messagehelp
