This is correct IMNSHO - architecturally speaking, Pentium = i586, Pentium
II = i686. I'm not sure how "pentium2" and "pentiumii" managed to be i786,
but it's incorrect. AFAIK, the Pentium III is also "i686" (don't quote me
on that!) - certainly my PIII system is classed as 'i686'. There was some
recent talk on the LKML of what the designation for the PIV should be, and
the concensus seemed to be 'i786' IIRC.
So..after that minor ramble, yes - I think the pentium2 and pentiumii
aliases should map to i686 ;-)
How about simply calling pentium2 "pentium2"? We could also call
pentium3 "pentium3", and pentiumpro "pentiumpro". Do you get the
Seriously, inventing "more logical" names is a silly exercise.
Some packages might want to make a distinction between exact CPU
types. GMP is one such package, where there has a very significant
