AMD's processors also fall into the same category. http://en.wikipedia.org/wiki/X86-64 Since the 64-bit ( x86-64/amd64) processors are backward compatible, 32-bit kernel and user land can be used on these as well. "Intel Atom is the brand name for a line of ultra-low-voltage x86 and x86-64 CPUs (or microprocessors) from Intel, designed in 45 nm CMOS and used mainly in netbooks, nettops, and Mobile Internet devices (MIDs)" http://en.wikipedia.org/wiki/Intel_Atom Hope that clarifies that part. > > Second if its true from 11.04 there won't be a separate UNR then how > would it affect atom processors > > > > Also the lpia arch that was used for the Netbooks, has also been dropped > for > > a while now. > > LPIA Low Power on Intel Architecture > > what do you mean by dropped, and by who > is it that atoms are no longer low power or is it that Ubuntu has > dropped support for atom processors > lpia has been dropped since 10.04 Lucid The announcement of that decision is here : https://lists.ubuntu.com/archives/ubuntu-devel-announce/2009-November/000643.html > > which then leads me to ask - whats the point of linux (or ubuntu) on > netbooks if they don't support atom processors > > thanks > ram > > The Atom processors are part of the same larger x86 and x86-64 arch, so its not a significant problem.
