Powermac G5 - unable to boot from Cd

Hi, all!

I oicked a Powermac G5 (2003) which had the hard disk removed. So I bought a 160 GB SATA hard drive and put it in. Then I bought the original MAC OS X v 10.2 install Cd's. So far it seemed that this was all I needed to make it run. Unfortunately I can not get it to boot from The CD. All I get is the gray screen with the folder-shape smiley face alternating with the question sign. I tried holding down the C key, also the Cmd+Opt+Shift+Del key combination but, the result was the same. I could load the Open Firmware and I tried to boot the cd using command: Boot cd:, \\:tbxi. This was the response: load-size=258b2 adler32=878490d1

Parsing <CHRP-BOOT>

Bootinfo is not compatible

I also proceded the NVRAM and PRAM reset, but didn't help.

I will apreciate any help or advice. Thanks in advance.
