Now , I am thinking that dropping i386 is not so much useful because - 64 bit CPU will consume more power than only 32 bit CPU . If a job can be processed by a 32 bit CPU , it is not necessary to use a 64 bit CPU . This will reduce size of CPU , and for small devices means less power . - FreeBSD is a "basic" operating system , in the sense that it is used in many diverse areas . To support very small and power efficient 32 bit processors , FreeBSD has primary importance . - Distributions based on FreeBSD , may decide to drop i386 , and I support their decisions because they are targeting a special area such as Intel like processor using desktops . In that case , trying to support i386 is only a waste of resources . Even a distribution may only support i386 or only another 32 bit CPU when its target does not include 64 bit . In that case also trying generate a 64 bit distribution obviously will be useless for them . For reasons such as above supporting i386 ( or 32 bit ) distributions by FreeBSD will be useful up to disappearing of i386 like processors from the market . Thank you very much . Mehmet Erol Sanliturk
