Hi,

I'm trying to write an appropriate CPUTYPE entry for
/etc/make.conf for the following machine:

CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (2799.95-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0xf41  Stepping = 1
  Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,
                      SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,
                      DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Features2=0x441d<SSE3,RSVD2,MON,DS_CPL,CNTX-ID,<b14>>
  Logical CPUs per core: 2

I've read the appropriate sections in the make.conf(5)
manpage, /usr/share/examples/etc/make.conf and even
/usr/share/mk/bsd.cpu.mk, but they don't really help.

So far I've been using "CPUTYPE=pentium4", but I wonder
if "nocona" would be better, however I'm not sure if my
CPU above qualifies as a nocona one.  I think the main
difference is that nocona supports SSE3, and SSE3 is
indeed listed in the CPU features above, so ...

Does anybody know for sure?  Thank you very much in advance!

Best regards
   Oliver
