  1. Hi all. I am installing Funtoo on a Lenovo C200. It has an Atom D525 processor, and the motherboard supports a maximum of 2 GB of memory, so I want to use Funtoo in 32 Bits, but in the Funtoo database, this processor appears inside the "atom 64" subarch which contains these Flags: mmx sse sse2 sse3. When analyzing my CPU with the command "lscpu" I see that it does not have sse3. And if I go to the subarch "atom 32" there is also the Flag sse3. How can I perform an installation in which Funtoo perfectly matches the processor and get the most out of it? I have been researching and an option would be to install the generic32 subarch and then recompile everything by modifying make.conf ? But if I set the autodetection (march = native) will it change everything from 32 bits to 64 bits since the processor is 64 bits? I clarify that although the processor is 64 bits, I want to use it in 32 bits only, because the motherboard supports a maximum of 2 GB of memory. Could someone give me a hand with this please?

  2. I have a desktop with an Intel 5820K in it. I am well versed with CPU architectures, so I know it is a Haswell-E, i7 processor. However, what subarch should I use for the installation? I would guess intel64-haswell, but the 5820K is a 5th generation i7 CPU and the Haswell subarch only mentions 4th generation. Will a native Haswell-E subarch be introduced soon?
