I'd like to build Ubuntu LTS 12.04 from source (kernel+daemons) on very old hardware. The hardware I'm on is i486 cpu on a pc104 single board computer. Most live cd's have trouble getting further than just booting on the computer , it has 512mb ram but less than 512mb hardrive space and very slow cpu. I can't get the ubuntu minimal cd to get past just booting, so I'm trying out this cd next http://www.ubuntu-mini-remix.org/. If I can't get a really small and stable ubuntu to run on this, then I'm going to try Gentoo next. I want to install a tiny ubuntu on this old harware ,I've done lots of googling but havn't found much. Tinycore linux works good on this hardware though(microcore to be exact). I just want a very tiny ubuntu(without xorg+DE) to work on extremely this old hardware . Is there some way I can install Ubuntu from another Linux's Live cd? I know you can do this on gentoo. What are your recommendations for installing a tiny very basic ubuntu/linux based server distro on very old hardware?
the best recomondation I can give you is to use the Ubuntu Server 12.04.2 LTS select the 32 bit version. You will not have anything as far as Xorg the only thing you will have is just the kernal and the demons that is needed along with whatever you whant to install. you might whant to take a look at this guide it will give you step by set instructions on installing and setting up Ubuntu server.
