Mod chip is the best way to boot PS2 games.
Go for a Messiah/Clone if you can get one, as this will save you a lot of hassle.
All you need to boot games with this chip is to put it in and play.
Info on different chips can be found all other the net.

This has burning guides for Nero Burning Rom CDRwin and Clonecd.
And also has boot guides.
To copy a DVD-ROM game using your CDRW you need a DVD Rip guide. This basically cuts bits out of the game to make it small enough to fit on a CD.
In my experience a copied game is not as good as original, my backups sometimes have problems on movies or sound.
This could have something to do with my laser in my ps2 or the quality of my blank media.

Still got time for the newbies!
