suggestions as to witch Linux OS I should down load

I am a rookie, I need some suggestions as to witch Linux OS I should down load to program the board?
Slackware?

Slackware would work for running on your desktop or laptop computer and allow you to work with a BeagleBoard. Pretty much any Linux distribution will work but Ubuntu might be a bit less work to get started with compared to Slackware if you're going to be installing it on a desktop or laptop that doesn't already have a Linux distribution installed.

I believe you’re asking which Linux to run on the beagleboard, correct?

Hi, on my beaglebone I have ubuntu Oneiric 11.10
U can go here http://elinux.org/BeagleBoardUbuntu#Demo_Image to get it
and its easy to put on sd card and ready to load on the beagle

Its really nice, a lot of drivers are included
I think much better than the original distribution
