Nano linux works great but I wonder how to install it on local harddrive I didn't see an install option in it. Now I dld the Antix.... I will keep you posted guys.

I am writing this on a ancient Gateway laptop with a Celeron processor and 256MB of memory that is running Puppy Linux 6.0 with no problems. Wireless internet, printer, mouse, etc. all work fine.

dear OP, antiX is the distro that is usually recommended most for newbies on ancientware.

...built from? Build on...

I don't $ee why $omeone wouldn't try numerou$ ba$e $y$tem$ (i.e: Slack, RedHat\Fedora, Debian, &c...) to find what variant$ they may like more?

Why are you trying to install or use Kali? If you're not a security professional with some decent Linux knowledge you shouldn't even bother looking at Kali -- it is not designed for you:

Steep learning curv /!

Well, I will not consider myself a security professional (it will be an arogance from my part) but as at last paragraph it said on their page:
Until a 1 year ago I didn't encountered a Linux distribution with so many tools for networking and security, so well organized and working too, with links to documentation if it doesn't included yet, as Kali (then was named Back Track).
I worked on RH, Slackware, Debian, FreeBSD as servers config and few others I even don't remember their name because I didn't last long enough on it if lacked many tools - it just doesn't seems right to search entire Internet for networking or security tools that has to match my specific OS distribution version, kernel version and packaging extensions (let's say, for the sake of argument that is Slackware) and try to build it on my PC/laptop. I don't include here Antix & Nano because if in case of Antix is well enough for a desktop use day-by-day but Nanolinux instead just looks well, after me is very unsatisfactory.

By the way what you would define as sufficient skills for ?

Debian + JWM --- might be a good starting point.

512MB is alright as long as you keep your setup simple. I have a pentium 4 laptop with 512MB of RAM. I use it to watch youtube and read game guides while playing games on a better machine. And when needed as an ethernet to wireless bridge. It struggles a bit with an older intel GPU, but it's a 2.8GHz cpu which keeps it relevant. I really couldn't find much on your i855pm, but I'm assuming somewhere near 1.4GHz single core and 32 bit from 2004-ish. "cat /proc/cpuinfo" if you were currently running linux on it. More ram would be nice, but if you're going to spend more than $50 you might as well get a new-ish chromebook or hp stream. Even lower power, lower heat, and specs that favor todays 3D world for $200 and down.

For the Kali pae issue. You might want to see if they have a non pae version of 32 bit iso.
If they do. Use that one instead. More ram is always better but on my IBMA22M.

2 256MB sticks were the max the mother board could handle. SDRAM is what they took. I got pretty good money selling one to a high school kind that wanted to buy linux cred.

The other I mailed off to a needy user with limited funds.

Use AntiX: that's the sort of computer that it's intended for, so why mess about trying to customise Debian or whatever when the job's already been done? With Antix, you can run the Midori browser in 128 MB -- I've done it -- so 512 will be fine.

They didn't have non-PAE Kali Linux distro, but I found out some ideas on their forum for customize a LIVE Kali Linux to make a non-PAE one... I will announce if will work.
