ok right but it is harder for an average kernel compiler to find the SSE3=20
feature instead of the cpu's revision

but certainly it would be easy to suggest to consult sort of

grep -i feat /var/run/dmesg.boot

to see if or not in `man make.conf` or somewhere, what then makes it ok as =
far=20
as it is well explained=20

because all of them are 64bit but some older ones are not SSE3 capable, < 2=
50=20
I guess now but 252 is but not 100% sure


=2D-=20
