[CentOS] Minimal installation How-to?

What about a PIII 550 Pentium...is it 586 or 686...sorry...dont know
that ;-) Would the minimum CD support that?

Also, Karan said something about it installing server components...I
have a query here...What server components? suppose I want to install
only the base OS, selinux & INN...would I get more than what I
want?...do I need to do anything specific with anaconda?

Please ./configure the reply for a complete dumbo ;-)

Regards to all.
Sanjay.
