try visiting the os manufacturer website.
I have tried them ALL, and Caldera was the easiest to install on my 400 celeron machine.
it did not work on my p2-266 w/ monster fusion video, neither did ANY redhat. I got Redhat 6.1 and mandrake 7.0 running on a dell GX1 500mHz at work, and it(mandrake 7.0) looked awesome. Linux can be a pain, and trying to get it running right is nearly impossible for a newbie. I did get my machine at work(dell GX1 400 mhz) on our network and got samba running, but could not get it on the net....strange because we have a linux dns server, haha(which I hate) the internet "police" set that up. All I can say is you have to do ALOT of reading and pend ALOT of time to get linux running as smoothly as windows(
) Don't give up.
