Is possible to install Centos 5 on a 586 CPU? (cpu_type = 5)
Thanks a lot.

No. I think there was some interest in making this happen at some point:

However I'm not sure that it will end up happening:

Pardon me, but you CAN install CentOS 5.1 on any x86 CPU. If your CPU is a valid 64-bit CPU, you can install either the i386 version (32-bit) or the x86_64 version. You may not get full support of specific CPU instructions that are available ONLY on your particular CPU, but the right one will run.
I had 586 CPUs on two different machines at work way back when 5.0 came out, and the x86_64 installation ran just fine on both.

Correct - my mistake (see? I do that...).

Thanks a lot you guys. So, it seems that it's not possible to install Centos 5.x on my i586 CPU right?. I've seen somewhere that there is an vmlzi586 boot option in Centos 4.6.... ¿Do you think that this version could work for me?
Thanks.

Yes ... centos-4.x works fine on i586 and will for its lifetime.

Is this what you are talking about:

If this is what you are talking about, I have to tell you, C5 runs on these better than I could ever get C4 or C3 to run. They have been rock solid and I am using a flash card for the disk mounted noatime. The box is one of those mini-itx things. C4 and C3 would randomly panic. Usually within the first 24 hours.
If this is not what you are talking about, feel free to ignore me.

i586 is the original Pentium and Pentium/MMX (60Mhz to about 233Mhz) as well as the clones you mention above, while i686 is the Pentium Pro, P2, P3, P4, and Core, as well as various clones.
for completeness, there's also i386 (the intel 386 processor) and i486 (the intel 486, as well as early K6 versions).
anything prior to i386 wasn't even 32bit and couldn't possibly run linux (I do somewhere have a version of Microport System V Unix for i286 16bit protected mode)

There is no such thing as a 64bit i586 CPU.
With regards to Intel CPUs, the original Pentiums are i586. Everything after that (PentiumPro, PentiumII, III, and IV) is i686. Earlier PentiumIV are 32bit only, later chips added the 64bit instructions and registers.
The CPUs are backwards compatible with older software.

So, what is a "valid" 64bit CPU? I have a DEC Alpha in the basement that is most certainly 64 bit, but can't install the i386 or x86_64 version on it. How about Sparc or HP-UX boxes? Are they valid 64 bit CPUs?

Grrr - we were discussing x86 CPUs. Alphas, SPARCs, Itaniums and HP PA-RISC are NOT x86.
Can we try to keep our discussions in context?
(heavy sigh, nanoo, nanoo)

I suspect he meant specifically x86_64... sure, there's lots of 64 bit processors that aren't x86 based, including Intel Itanium (ia64), DEC Alpha/AXP, Sun UltraSparc, HP PA-RISC, IBM Power4/5/6 and PowerPC, etc etc.
There /are/ linux builds for most (all?) of these, but not RHEL/CentOS distributions.

Those are completely different arches. None of them are x86.
In the context of this discussion, "valid" 64bit CPUs are newer PentiumIV, Athlon64, and later CPUs.
