I want to get a look at Cents-6 The computer is a portable Thinkpad T-42 The base OS is Windows XP Professionnal
I tried to use both Microsoft Virtual PC and Oracle Virtual Box with the same result I boot from the CD (wich have been burned from an ISO downloaded from a Centos -6 repo). The version is CentOS-6.0-i386-bin-DVD.iso
With each virtual machine I get this result at the beginning of the installation: "This kernel requires the following features not present on the cpu pae" "Unable to boot - please use a kernel appropriate for your CPU"
I undeerstand that perhaps the computer processor is too old. But is there a patch to overpass this problem?

In one word: No.

Thinkpad T-42
http://en.wikipedia.org/wiki/ThinkPad
ThinkPad T40-series Includes the T40, T41, T42, T43, and associated p series (for performance; e.g., T43p). A typical 14.1-inch (360 mm) T4x weighs 4.9 lb (2.2 kg), slightly less than the 600-series, and features an Intel Pentium M Processor (ranging from the Intel Pentium M at 1.73 GHz to the Intel Pentium M 770 at 2.13 GHz),
Hope that helps.

You need to have a cpu that has a hardware visor. Otherwise, the only other option will be qemu which is slow.

In virtualbox click the option under cpu that it has PAE.

Oops, taking that back, virtualbox is not like kvm or xen. It looks like that it does not need a hardware hypervisor.

Hrrm, seems as if the ISO may be using a PAE kernel by default. PAE is a kernel that will be able to make use of more than 4GB of RAM with i686.
Ah, I see it's apparently a decision by RH. I assume there's some logic in it, though I don't know what it is.

See if it's possible to add PAE to the machine settings in VirtualBox. Settings=>System=>Processor
There's a checkbox for PAE. Try checking that off and seeing if it helps.

The box is already checked but the CPU doesn't have PAE capability so it's useless.
It won't be a bad thing thatthe install may do a choice of a cpu with or not the capability of PAE as it was in the past.

Red Hat decided that this newer version of RHEL(CentOS) *must* have PAE support by CPU to be installed. I think they would even prefer to loose i386 branch all together. Indication was when they supported (or just forced, cant remember witch) Virtualization only on x86_64 on RHEL/CentOS 5.x.

They only support KVM as a host technology for virtualization now. KVM requires the CPU virtualization extensions to function. The functions are only available on the CPU when in 64bit (long) mode.
There are sound technical reasons for this and it wasn't just them being stubborn to drop an architecture.

I had (and still do) rpm packages (kvm-84-1.i386) for KVM on 32-bit platform, made by L. Farkas. I used it successfully up to 5.4 (I think) when I reinstalled my server and used x86_64 version. Maybe those requirements are of the newer date?

I might have messed up the quoting here, not sure if Michael was the OP, but at any rate, there is this post on SL forums about installing a non-PAE kernel which might be useful.

Or ... keep an eye on this ELRepo bug tracker:
http://elrepo.org/bugs/view.php?id=153
kernel-ml for EL6 will have a non-PAE flavo(u)r. It is now cooking.
