I have not touched my Centos systems for over a year; it is time to get current to do some new, interesting things.
So of course, 6.3, but which install?
I run a local repo that I rsync from a mirror near me. So I believe I can use the Netinstall iso, but which one?
How do I determine if I have a i386 or x86_64 processor?
If x86_64 how do I determine if I use EFI or not?

Almost all systems sold in the last few years are 64 bit, so if in doubt, try installing. If the CPU is 32 bit only, it'll fail to install almost immediately. If you know what CPU you have, you can look it up on the manufacturer's website or on wikipedia to see what features it has.
As for what media, well, that depends entirely on how often you plan to (re)install and what your bandwidth costs. It also depends on what you want to use CentOS for. For me, I usually use the minimal install and just install what I need, but it's not at all user friendly as almost nothing but the bare system is installed (not even man pages!).
Welcome back :)

But what is the difference for the x86_64-netinstall vs x86_84-netinstall-EFI?

the latter is for EFI systems (EFI instead of BIOS), while the latter would be for traditional BIOS.

So I need the liveCD to boot to get to this point? Which one.
Oh, my current systems are running Centos 5.4 (I think) and only have 256Mb and 512Mb memory. To go to 6.n, I need more memory, like 1Gb. So I have a couple systems on the floor that I dropped new drives into so they don't have a running OS yet.

The i386 one should boot on both 32/64bit platforms, but with only 256/512M of RAM I don't think you can install CenOS 6.x.
The CPU flag you're looking for in /proc/cpuinfo is "lm" (Long Mode).

IIRC, 512 s/b enough for a text-mode install.

And then you can't work with your partitions. You are stuck with the defaults. That is only one challenge with text-mode install that I never liked. I accept that I need new systems with 1Gb. The Compaq SSFs I have are around 15 years old and cannot support more memory. Time for somethings a little newer.

I've got a couple of VMs running minimal 6.3 with 256 MB.
They're only good for testing purposes against very low activity stuff but they run quite happily.
Just don't try running '# yum update' though. They crash real good :-)
Cheers,
Phil..

Well I finally got the one system booting. It is showing as a i386 type system. Thanks for the help. Now to do a first install...

As Radu mentioned, check /proc/cpuinfo for "lm".
If x86_64 how do I determine if I use EFI or not?
Check the output of `dmidecode` to see if UEFI is supported.
