CentOS - Jun 2008 - centos 4.6 - 586 install - how to get that to a 486 level if possible

Is there a method to get a 586 (i586 text) install  to a 486 level?
I am looking for information guidance on this.
I have looked into using debian/386 which stinks in my opinion, 
slackware doesnt quite have it either.

So I am wishing/hoping there is a NOT TO painful way to get a 586 install
to run on a 486 chip.

I have been searching but havent found anything useful. If anyone knows 
what might need
to be done I would appreciate it.

Sorry, I have no clue about your question. However, I have several
AMD K6 chips (pentium-equivalent) lying around should you trip over
a motherboard that'll run them. That would solve your 486 problem, I
think, so let me know if such a chip would help you out.

This would be almost impossible with centos.

The reason is that there are things that glibc will compile in that are 
not i486 compatible

You would be much better off trying to do this with debian I think.

If it were possible, it would be by installing the i386 glibc, i386 
openssl and editing the kernel spec file and the config file.

You can try to change the processor type to i386 or i486 and see if it 
will work ... however I do not think it is possible on other than 
centos-3 to get an i386 compile.

Fred - thanks for the offer - however I do have a specific device I am 
targeting. Ebox2300sx.
I have no options on the hardware. It would be a great solution hardware 
wise but software is
being a bit of a pain at this time.

Johnny - thanks for the info. I actually have debian booted on the 
device but then EVERYTHING
is so much different on debian than centos. I was also trying a redhat 9 
install and put a 2.6 kernel on it.
However, I realize this is not the best solution. BUT - to try it out 
and get something working with
the other programs I need I thought that might be a valid short term 
path to check things out.

Thanks guys,

Jerry

I tried RHEL 3 (I believe) on a Pentium class system, and that did not work
well.

For everything but the kernel, there was a 386 version available (glibc,
ssl, etc), so we recompiled the kernel for the 586.

Unfortunately, glibc, when you compile it for anything below a 686, did not
support NTPL threads, causing nothing but heartache.  Luckily, before we got
too far, we learned we didn't have to target the Pentium based computer
anymore.  I am happy we didn't have to validate everything still worked when
something as major as glibc is rebuilt (since I started looking whether it
was possible to rebuild glibc for 586 and NTPL).  Kernels are less risky,
since people rebuild them more frequently.
