Just a curiosity... I know that knoppix is based upon Debian Woody distribution that use a i386 processor architecture. Why have I seen at Distrowatch.com (Knoppix page) that knoppix use a i486 processor architecture ???

Linux distros are based on x86 architecture (among others). Some distros are made in such a way that they are optimized for 386, 486, 686 or K7 etc. This is not to say that a distro that is optimized for 686 will not work on a 486.

this means that all Linux Distro for PC support all x86 processor but someone have no particular optimization, other are optimized for a particular processor i.e.: Debian:386, Mandrake: 586, Yoper:686, and so on ? Is right ???
And Knoppix ??? i486 or i386 like Debian ???
Thanks!

Correct

Some distros offer optimized versions for 386, 486, etc. Some only offer x86. I have used standard x86 as well as K7 optimized distros and really didn't notice any difference. Certainly those distros serve a purpose and on a problem machine it would be wise to use something specifically designed for its architecture.
And Knoppix ??? i486 or i386 like Debian ???
Since Knoppix is a combination of packages from stable, testing, unstable that were selected because of their compatibility with each other, Knoppix bootable cd requirements, etc. I don't think it is optimized for any particular platform. In fact it is an attempt at being compatible with as many pc's as possible.

Not necessary. IIRC, the pentiums added some new instructions which aren't available on a 486. Can't remember exactly what it is. I took that class on Computer Architecture too long ago.
