Compile kernel for older processors (i586)

[lifeboy]

Is it possible to compile an Ubuntu Kernel for sources for an i586 processor after Maverick (10.10)? I found this note [3] here (https://help.ubuntu.com/11.04/installation-guide/i386/hardware-supported.html#ftn.id2768768), that indicates that it is possible.

Which option(s) in the .config file should one then enable to compile a newer Ubuntu kernel without cmov (and cx8?) support? Would selection a 486 type processor be all that's needed?

I'm currently running 10.04 on a Vortex processor for thin clients, so if there is a way to use a newer version I'd like to explore it.

That is for the Ubuntu built and patched kernels... I'm wondering if that is aN Ubuntu thng or a Linux Kernel thing? I don't know. Because when I test kernels and/or have kernel bugs, launchpad has me test it against the mainline PPA, which is from the Upstream source code, without any Ubuntu thrown in yet. Having said that- Is your "condition" true for the generic mainline kernels without the Ubuntu added patches and extras? Have you tried one?

Here you go.

Download the "x86" image and header file, with a matching "-all" header file. Put them into their own directory, go to that directory from a terminal and


sudo dpkg -i *.deb

I don't have the time at the moment to investigate this, but I will in future. In a sense this is a scouting question of sorts, to see what I can learn from the experience of others. Thanks for your comments.
