Here is an actual download link for smart start cd

otherwise you will only find pay links
you will have to choose an old old opsys to get a 5.5 link, like windows server 2000
I dunno if you need smartstart 5.5, 6.x or 7.1
You will have to trial and error on that G2
Don't worry about the opsys so much, just download and burn the isos and start to trial and error
